Background and Purpose: The effects of B-vitamin combinations on the prevention of cardiovascular diseases, such as myocardial infarction (MI) and stroke, remain controversial. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) over three decades to evaluate the association between B-vitamin combinations and mortality and arterial thrombotic outcomes. Methods: PubMed, Embase, Web of Science, and the Cochrane Library were systematically searched for RCTs with minimal duration over 24 months published between January 1996 and November 2025. Two reviewers independently screened studies, extracted data, and assessed risk of bias using the Cochrane Risk of Bias 2.0 tool. Random-effects models were used in this meta-analysis to calculate pooled risk ratios (RRs) and 95% confidence intervals (CIs). Results: Thirteen randomized trials enrolling 68,363 participants across both primary and secondary prevention populations were included. B-vitamin combinations were associated with a nonsignificant reduction in stroke and 3-point major adverse cardiovascular events (MACE) (stroke: RR 0.91, 95% CI 0.81-1.04; MACE: RR 0.93, 95% CI 0.86-1.01). No significant effects were observed for all-cause mortality (RR 1.01, 95% CI 0.96-1.06), cardiovascular mortality (RR 0.97, 95% CI 0.88-1.07), or MI (RR 0.97, 95% CI 0.91-1.03). In primary prevention populations, B-vitamin combinations were associated with significant reductions in stroke (RR 0.79, 95% CI 0.68-0.93) and MACE (RR 0.80, 95% CI 0.69-0.92). A modest reduction in MACE was also observed in secondary prevention populations (RR 0.91, 95% CI 0.83-0.99). Between-study heterogeneity was minimal to low for ischemic outcomes, supporting the robustness of these estimates, whereas substantial heterogeneity was observed for mortality outcomes in secondary prevention populations. Conclusions: The evidence is limited by heterogeneity in trial populations, vitamin formulations and doses, and outcome definitions, with substantial between-study inconsistency for mortality outcomes and imprecision in subgroup estimates derived from a small number of contributing trials. Overall, B-vitamin combinations do not confer consistent benefit for major cardiovascular outcomes but may reduce stroke and MACE in selected primary prevention populations, suggesting that baseline cardiovascular risk and regional folic acid fortification modify treatment effects and should guide future trial design and clinical use.

OBJECTIVE: Hyperhomocysteinemia (Hcy) independently predicts coronary heart disease (CHD) and adverse cardiovascular events. Although folic acid plays a key role in Hcy metabolism, the effect of combined B-vitamin supplementation (folic acid, VB6, and VB12) on clinical outcomes in CHD remains uncertain. METHODS: A systematic search of PubMed, Embase, and the Cochrane Library was conducted from inception through April 2025 using MeSH terms including "folic acid," "vitamin B6," "vitamin B12," "coronary heart disease," and "homocysteine." A random-effects model was used for meta-analysis. RESULTS: Thirteen studies involving 14,539 participants were included in the meta-analysis (7,338 patients treated with folic acid combined with vitamin B complex and 7,301 controls). Combined B-vitamin supplementation significantly reduced serum Hcy levels [mean difference: -2.36; 95% confidence interval (CI): (-3.09 to -1.62); p < 0.01] compared with any single-nutrient regimen. The incidence of vascular restenosis was lower in the intervention group than in the control group (risk ratio: 0.65; 95% CI: 0.44-0.95; p < 0.05). However, no significant differences were observed in the incidence of major cardiovascular events (p = 0.78) or cardiovascular-related mortality (risk ratio: 0.96; 95% CI: 0.85-1.07; p = 0.44). CONCLUSION: Combined B-vitamin supplementation effectively lowers serum Hcy levels and the incidence of vascular restenosis in patients with CHD. However, its impact on cardiovascular events and mortality remains inconclusive. Plain Language Summary: Meta-analysis of 13 RCTs (n = 14,539): combined B vitamins lower serum HcyCombined B-vitamin supplementation lowers vascular restenosis in CHD patientsExerts no significant impact on major CV events or mortalityHcy-lowering appears CHD-specific; broader CV benefits remain unproven.

BACKGROUND AND AIMS: We have evaluated the efficacy and tolerability of two food supplements (FS) containing flavonoids (naringin and hesperidin); same doses of B3, B6, B9 and B12 vitamins, and two different doses of a blend of Mentha spicata leaf extract and Amaranthus caudatus seed flour, in subjects with borderline high total (TC) and low-density lipoprotein cholesterol (LDL-C) levels. METHODS AND RESULTS: 114 Participants (18-70 years) with TC levels 200-239 mg/dL, (5.18-6.19 mmol/L) and LDL-C (<159 mg/dL) were randomised into three groups to receive for 90 days the lowest (n = 38, Treatment A), the highest dose of the FS (n = 38 - Treatment B), or placebo (n = 38). Treatment B was associated with a significant reduction in LDL-C (∼31.5 mg/dL;-22%) and TC (∼19.5 mg/dL; -9%), along with an increase in high-density lipoprotein cholesterol (HDL-C). The greater efficacy of Treatment B containing the highest dose of vegetable extracts is likely attributable to its higher M. spicata extract content, as judged by high-resolution mass spectrometry analysis of the preparation. CONCLUSION: The combination of different FS ingredients with different mechanisms of action can be a valuable strategy for improving lipid profiles in subjects with borderline high TC and LDL-C levels.

This study was conducted to evaluate the effects of bromelain supplementation on disease activity and quality of life (QoL) in patients with ulcerative colitis (UC). Seventy individuals with mild-to-moderate UC participated in a randomized, triple-blind clinical trial. Participants were randomly assigned to receive either maltodextrin as a placebo or 400 mg of bromelain daily for eight weeks. QoL and Simple Clinical Colitis Activity Index (SCCAI) scores were assessed. All results were analyzed using both intention-to-treat (ITT) and per-protocol (PP) approaches. The only demographic factor that differed between the two groups statistically significantly was gender (p = 0.01). Additionally, the mean difference in vitamin B6 consumption variations between the bromelain and placebo groups was significant (0.39 ± 0.86 vs. -0.44 ± 1.43; p < 0.001). There was no considerable difference detected for the other nutrients. The bromelain group had considerably higher changes in their SCCAI score in comparison with the placebo group (-3.29 ± 2.17 vs. -1.11 ± 1.71; p < 0.001). There was no considerable difference in changes in QoL questionnaire scores between the intervention and control groups (3.76 ± 6.18 vs. 3.91 ± 4.30; p = 0.90). After correcting for baseline, the findings remained significant for the SCCAI variable but not for the QoL variable (p < 0.001 and p = 0.99). In UC patients, the severity of the disease is reduced by bromelain supplementation, which is an alternative therapy.Trial registration: The study protocol received approval from the Ethics Committee at Iran University of Medical Sciences "IR.IUMS.REC.1402.125" and was registered with the Iranian Clinical Trials Registry "IRCT20191105045340N2" on 09/07/2023. © 2025.

(#)Contributed equally BACKGROUND: Glaucoma is a leading cause of irreversible blindness, characterized by progressive degeneration of retinal ganglion cells. Current treatments primarily lower intraocular pressure but do not directly provide neuroprotection. Preclinical studies from our group have identified dysfunction in one-carbon metabolism as a contributor to glaucomatous neurodegeneration in rodent models. The Interventional Vitamin Mix Glaucoma Study will evaluate whether 12 months of supplementation with key one-carbon metabolism cofactors and precursors (vitamins B6, B9, B12, and choline) can improve inner retinal function and provide neuroprotection compared with standard care alone. METHODS: The Interventional Vitamin Mix Glaucoma Study is a Phase 2a, open-label, randomized, two-arm clinical trial. Participants will be assigned in a one-to-one ratio to receive either daily one-carbon metabolism supplementation plus standard care or standard care alone. The study will enroll 80 patients with primary open-angle glaucoma, normal tension glaucoma, or pseudoexfoliation glaucoma, each with mild-to-moderate visual field loss in at least one eye. Recruitment will take place from March 2025 to March 2026 at St. Erik Eye Hospital, Karolinska Institutet, Stockholm, Sweden. The primary outcome is change in the photopic negative response measured by full-field electroretinography. Secondary outcomes include changes in visual field parameters, retinal nerve fiber layer thickness, and ganglion cell-inner plexiform layer thickness. Exploratory outcomes will include changes in blood-based metabolomic and DNA methylation profiles. DISCUSSION: One-carbon metabolism-based supplementation has been shown to reduce retinal ganglion cell loss in rodent models of glaucoma. This trial will investigate whether such supplementation improves retinal function and confers neuroprotection in patients with glaucoma. The use of full-field electroretinography as the primary outcome aims to detect early functional improvements in the retina. If successful, this approach could support a low-cost, widely available neuroprotective strategy to be used alongside existing intraocular pressure-lowering therapies.

IMPORTANCE: Treatments for men seeking fertility care are limited. Antioxidant supplements have been widely studied as a new treatment option, but these studies have had conflicting results. OBJECTIVE: To assess whether treatment of men seeking fertility care with an antioxidant supplement can improve semen quality and pregnancy rates compared with a placebo. DESIGN, SETTING, AND PARTICIPANTS: The SUMMER trial was a multicenter, double-blind, placebo-controlled randomized clinical trial conducted in 21 hospitals and private fertility clinics in the Netherlands. Male patients in these centers were enrolled between May 2018 and February 2024, and follow-up of the primary outcome was completed in December 2024. Eligible participants were men aged 18 to 50 years with female partners aged 18 to 43 years, who sought fertility care and were advised to undergo expectant management, treatment with intrauterine insemination, in vitro fertilization (IVF), or intracytoplasmic sperm injection (ICSI). Couples treated with ovulation induction only or IVF for bilateral tubal pathology were excluded. The men were randomly assigned to receive an antioxidant supplement or a placebo. Intention-to-treat analysis was performed for all outcomes. INTERVENTIONS: The antioxidant supplement (Impryl) was a tablet to be taken daily for 6 months. It contained betaine (200 mg), L-cystine (200 mg), niacin (16 mg), zinc (10 mg), vitamin B6 (1.4 mg), vitamin B2 (1.4 mg), folic acid (400 µg), and vitamin B12 (2.5 µg). The placebo tablet and its packaging were identical to those of the antioxidant supplement. All participating couples received standard infertility care. MAIN OUTCOMES AND MEASURES: The primary outcome was ongoing pregnancy conceived within 6 months after randomization. Secondary outcomes included semen parameters, sperm DNA fragmentation, fertilization and embryo utilization rates after IVF or ICSI, biochemical and clinical pregnancy rates, first-trimester pregnancy loss, ectopic pregnancy rate, cumulative number of pregnancies, time to pregnancy, and adverse events. RESULTS: A total of 1171 men (median [IQR] age, 34 [31-38] years; female partners' median [IQR] age, 32 [30-35] years) were included in the data analysis, of whom 591 were in the antioxidant supplement group and 580 were in the placebo group. Ongoing pregnancy rate within 6 months was not significantly different between the 2 groups (193 of 571 [33.8%] vs 208 of 555 [37.5%]; adjusted odds ratio [AOR], 0.85 [95% CI, 0.66-1.09]; P = .20). Within the window of optimal treatment effect between 4 and 6 months (considering a spermatogenesis cycle of 72 days), ongoing pregnancy rate was significantly lower in the antioxidant supplement group compared with the placebo group (69 of 446 [15.5%] vs 95 of 442 [21.5%]; AOR, 0.66 [95% CI, 0.47-0.94]; P = .02). There were no significant between-group differences for the secondary outcomes. CONCLUSIONS AND RELEVANCE: This randomized clinical trial found that ongoing pregnancy rates did not improve with the antioxidant supplement compared with a placebo. Therefore, the investigators do not support its use in men seeking fertility care. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03337360.

CONTEXT: Elevated homocysteine levels are associated with brain atrophy and dementia, with B vitamin supplementation a possible low-cost intervention to help mitigate the deleterious impacts on brain health. However, prior meta-analyses have produced inconsistent results, with unexplained heterogeneity, while the quality of evidence has not been assessed. OBJECTIVE: This systematic review, meta-analysis, and meta-regression sought to quantify the effect of B vitamin supplementation on global cognitive function in older adults. DATA SOURCES: PubMed, Embase, PsychInfo, Scopus, and the Cochrane Library databases were searched for randomized controlled trials (RCTs) from inception to June 20, 2024. DATA EXTRACTION: Eligible RCTs were derived from populations aged ≥60 years, with interventions of 26 weeks or longer comprising vitamin(s) B6, B9, or B12 of any dose or administration route, compared with placebo or usual dementia care. Studies must also have quantified global cognitive function at baseline and at end of treatment. DATA ANALYSIS: Seventeen RCTs, including 5275 participants, were identified. A small to moderate improvement (Hedges' g = 0.423; 95% CI: 0.188 to 0.657) in global cognitive function after supplementation was observed with considerable heterogeneity (I2 = 92.71; Grading of Recommendations, Assessment, Development, and Evaluations [GRADE] = very low certainty). A meta-regression identified that statistical outliers and single-blinded studies contributed to the pooled g and heterogeneity. Omitting these studies resulted in a small effect (g = 0.110; 95% CI: 0.034 to 0.186), with negligible heterogeneity (I2 = 15.39; GRADE = high certainty). The effect size did not differ between classifications of cognitive impairment (ie, intact cognition, mild cognitive impairment, and dementia) in subgroup analysis (P = .729). CONCLUSION: The pooled findings indicated there is high-certainty evidence that vitamin B6, B9, or B12 supplementation has a very small benefit on global cognitive function in older adults.

Electronic address: piradee@pedpmk.org. BACKGROUND: Levetiracetam commonly causes neuropsychiatric adverse events (NPAEs) in pediatric patients, including irritability and aggression. This study evaluated pyridoxine supplementation for reducing levetiracetam-related NPAEs in children and adolescents with epilepsy. METHODS: We conducted a prospective, double-blind, randomized, placebo-controlled trial at Phramongkutklao Hospital, Thailand (January-June 2024). Participants aged 1-18 years with levetiracetam-related NPAEs were randomly assigned in a 1:1 ratio to receive either pyridoxine (10 mg/kg/day, maximum 200 mg) or placebo for 8 weeks. The primary outcome was change in behavioral symptoms using a validated 30-item questionnaire (score range 30-90). Secondary outcomes included treatment adherence, time to behavioral improvement, and adverse events. Sample size (n = 102) was calculated to detect a 20 % difference in behavioral improvement with 80 % power. RESULTS: 102 patients were randomized (pyridoxine n = 51, placebo n = 51). Baseline characteristics-including age, sex, seizure type, and number of concomitant ASMs-were comparable between groups. The mean age was 9.2 vs 8.3 years (p = 0.363), and 52.9 % vs 51.0 % were female in the pyridoxine and placebo groups, respectively. Most participants (56.9 %) were on dual therapy, with a median of two ASMs in both groups (p = 0.94). Both groups showed significant behavioral improvement over 8 weeks: the pyridoxine group from 14.79 ± 6.87 to 11.54 ± 6.22 (p < 0.001); placebo group from 15.65 ± 8.26 to 10.47 ± 8.22 (p < 0.001). No significant between-group difference existed at week 8 (p = 0.468). However, multivariate analysis of behavioral change scores from baseline to week 8 revealed significantly greater improvement in the pyridoxine group (adjusted OR = 2.31, 95 % CI: 1.15-4.63, p = 0.020). No serious adverse events occurred in either group. CONCLUSION: While pyridoxine did not significantly reduce behavioral scores compared to placebo at the study endpoint, the greater improvement in change scores over time suggests potential benefit in mitigating levetiracetam-associated NPAEs. Pyridoxine may serve as safe adjunctive therapy for patients who have behavioral side effects while maintaining seizure control. Further investigation in larger multicenter trials with extended follow-up is required before recommending pyridoxine for routine clinical use. Copyright © 2025 Elsevier Inc. All rights reserved.

Electronic address: barbara.cardoso@monash.edu. Poststroke cognitive decline is a major form of disability in stroke survivors. Although dietary interventions have shown potential in improving cognitive outcomes in stroke-free populations, their effects on stroke survivors remain unclear. This review aimed to evaluate associations between diet and cognitive function in stroke survivors. MEDLINE, Embase, Scopus, and CINHAL were searched for studies from inception to 16 December, 2024. Eligible articles were observational and interventional studies on adult stroke survivors that evaluated the association/effect of any nutritional exposure/intervention on cognitive performance and dementia risk. Studies were excluded when an intervention was combined with nonnutritional treatment. Random-effects meta-analysis was used for similar randomized clinical trials. This review included 20 clinical trials and 14 observational studies assessing the intake of energy and proteins and a variety of single nutrients, as well as dietary patterns, single foods, and phytochemicals. Meta-analyses revealed a positive effect of energy-protein supplementation on global cognition [standardized mean difference (SMD): 0.62; 95% confidence interval (CI): 0.15, 1.08; P = 0.009], and a negative effect of B-vitamins (folic acid, vitamin B6, and vitamin B12) (SMD: -0.40; 95% CI: -0.72, -0.08; P = 0.02). Adherence to the Mediterranean-Dietary Approaches to Stop Hypertension (DASH) Intervention for Neurodegenerative Delay and plant-based diets, as well as higher consumption of fruits, milk, coffee, vitamin E, and selenium, were related to better cognitive outcomes; no significant association was observed for adherence to DASH and Mediterranean diets and consumption of vitamins D and C. Butter and sugar intake and calcium supplementation were associated with negative cognitive outcomes. Mixed results were seen for omega (ω)-3, tea, and plant extracts. The available evidence indicates that energy-protein supplementation may benefit cognition after stroke, whereas B-vitamin supplementation has no effect. The substantial heterogeneity among studies hinders conclusions about other dietary strategies. This review was registered with PROSPERO as CRD42024541785. Copyright © 2025 The Authors.

Background: A nutritional supplement based on medicinal plants (saffron and ashwagandha), tryptophan, and vitamin B6 could contribute to alleviating/improving mood and associated disorders. The aim of this study was to evaluate the potential benefits of this combination supplement. During the study period, participants underwent a period of forced home confinement due to the COVID-19 pandemic, which represented an unexpected impact factor. Methods: This open-label prospective trial enrolled a cohort of female employees who reported mild to moderate anxiety. The primary objective was to evaluate changes in the level of anxiety using the adapted Hamilton Anxiety Rating Scale (HARS) after 12 weeks of regular supplementation with Safromotive (two tablets daily, for 12 weeks). The secondary objectives were to evaluate health-related quality of life (HRQoL) and tolerability. Results: In total, 46 women with a mean age of 45.0 (6.5) years were included. A statistically significant improvement in HARS was observed, with a 7.5-unit decrease from baseline to 12 weeks (p < 0.0001) and from 4 to 12 weeks of supplement intake (p=0.0058). However, no significant changes were found during the lockdown period (between weeks 8 and 12 of the study). No relationship was found between women's sociodemographic characteristics and the HARS total score. A significant reduction in the HRQoL questionnaire score of 1.2 units was observed between baselines and 12 weeks of treatment (p=0.0273). At the end of the study, 78.6% of the women reported consistency the supplement intake during the study course. Conclusion: This nutritional supplement composed of saffron, ashwagandha, tryptophan, and vitamin B6 appears to improve anxiety and HRQoL, but confinement could have impacted the evolution of the outcome.

Homocysteine is an amino acid derived from methionine which is metabolized via vitamin B6 (pyridoxine)- and vitamin B12 (cobalamin)-dependent pathways. Supplementation of B vitamins has been shown to effectively reduce plasma homocysteine levels. Previous research has also demonstrated an association between lower plasma homocysteine levels and decreased risk of myocardial infarction, stroke, and venous thromboembolism. However, whether supplementation of B vitamins is associated with risk reduction in thromboembolic events and confers clinical benefits remains inconclusive. This review examines clinical trials published over the past 29 years to assess the effects of B vitamin supplementation on thrombotic risk reduction and homocysteine metabolism. The findings from these studies are inconsistent, and the impact of B vitamins on thrombosis prevention remains uncertain. Given the conflicting evidence, further clinical and translational research is necessary to clarify the role of B vitamin supplementation in thrombosis risk reduction.

(3)Department of Nutrition, Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran. BACKGROUND: Drug resistance poses a formidable challenge in managing acute manic episodes in bipolar I disorder, leading to suboptimal treatment outcomes. This study investigates the efficacy of folate and vitamin B6 supplementation as an adjunct to sodium valproate in improving treatment responses for patients experiencing acute mania. METHODS: In a randomized, double-blind, placebo-controlled trial, 43 patients diagnosed with bipolar I disorder presenting with acute manic episodes were enrolled. Participants were randomly assigned to three groups: one receiving folate (5 mg/day) plus vitamin B6 (80 mg/day), a second group receiving folate alone (5 mg/day), and a third group receiving placebo. Evaluations were conducted at baseline and after 3 and 6 weeks using the Mini-Mental State Examination (MMSE) and the Young Mania Rating Scale (YMRS). RESULTS: All groups demonstrated significant clinical improvements after the treatment period; however, the trends in MMSE scores showed no significant differences (p = 0.068). Notably, the reduction in YMRS scores significantly varied across groups (p < 0.001, effect size = 0.342), with the folate group demonstrating a significantly greater decrease compared to both the folate/B6 (p = 0.003) and placebo groups (p < 0.001). Recovery rates revealed that 80% of patients receiving folate showed over a 50% decrease in YMRS scores after 3 weeks, markedly higher than the other groups (p = 0.001). CONCLUSIONS: Our findings support the short-term use of folate as a beneficial adjunct in treating acute manic episodes in bipolar I disorder. However, the addition of vitamin B6 did not yield additional advantages. These results may inform future treatment guidelines targeting acute mania in bipolar disorder, advocating for folate supplementation as a potential strategy to enhance therapeutic outcomes. © 2025 The Author(s).

BACKGROUND AND AIMS: Recently Diabetes Mellitus (DM) has been associated with heightened susceptibility to malnutrition, suggesting that augmenting nutritional intake stands out as a potent therapeutic strategy for addressing malnutrition in individuals with DM. The aim of this clinical investigation was to evaluate the effect of DiabetEaze powder, a polyherbal nutritional formulation developed by us for nutritional management and glycaemic control, on patients with diabetic and prediabetic conditions. METHODS: A total of 143 type II diabetic (T2D) patients who were managing their diabetic condition through modern medicine, AYUSH medicine, lifestyle modification and 68 pre-diabetic patients, aged between 40 and 65 years, were randomly assigned into six groups: control, modern, AYUSH, lifestyle, prediabetic control and prediabetic trial. The treatment groups were administered 5 g of DiabetEaze powder two times a day after food for 6 months. Microminerals, vitamins, glycaemic parameters, Quality of Life (QoL), hematology, lipid profiles, Renal Function Test (RFT) and Liver Function Test (LFL) parameters, and electrolytes were evaluated at Day 0, Day 90, and Day 180. RESULTS: Out of 211 enrolled patients, 189 individuals successfully completed the entire 180-day duration of the study, indicating a retention rate of approximately 89.6 %. In our study, we observed a statistically significant elevation in the levels of vitamin D, B2, and B6 across all treatment groups. Besides, the treatment groups displayed a notable increase in zinc and manganese levels compared to the other minerals tested. Notably, the treatment groups demonstrated distinct mineral and vitamin profiles. In terms of metabolic markers, significant reductions in Fasting Blood Sugar (FBS)/Post Prandial Blood Sugar (PPBS) were observed across the modern, AYUSH, and lifestyle groups, while the modern group also showed a marked decrease in glycated haemoglobin (HbA1c) levels. Furthermore, overall QoL among the tested groups was also statistically significant. The consistent maintenance of normal LFT and RFT parameters and electrolyte levels across trial groups throughout the study duration indicates that the supplement does not induce liver toxicity or negatively impact hepatic function. CONCLUSION: In conclusion, the nutrients present in the DiabetEaze powder contribute to the effective management of nutritional status in diabetic people and thus effectively reduce sugar spikes by regulating PPBS and HbA1c levels, which is a critical aspect of its role in diabetes management. These properties benefit in managing diabetes-related outcomes and overall quality of life.

(#)Contributed equally PURPOSE: In the current study we evaluated a blend of ingredients containing mulberry leaf extract (to lower postprandial glucose of the evening meal), tryptophan (facilitator of the sleep initiation) to benefit sleep initiation and quality in adults with self-reported difficulties with sleep initiation. METHODS: Forty-three adults aged between 25 and 50 years enrolled in a randomized, crossover, double-blind, controlled trial. Participants received standardized meals with a glycemic load of 55 ± 10% and were assigned to receive treatment comprising a combination of mulberry leaf extract (750 mg), whey protein containing 120 mg tryptophan, zinc (1.35 mg), magnesium (12.6 mg), vitamin B3 (1.93 mg) and B6 (0.135 mg) and control (4 g wheat protein hydrolysate). Each intervention phase lasted 14 days separated by a washout period of 28 days. The primary outcomes were actigraphy-measured sleep onset latency and sleep efficiency. Secondary outcomes included continuous glycemic responses, mood, and cognition. RESULTS: A linear mixed model intention-to-treat analysis conducted on 42 participants found that the treatment reduced sleep onset latency (actigraphy: -3.82 mins, p = 0.026; self-report: -3.09 mins, p = 0.048). Treatment significantly reduced evening meal's postprandial glucose response (incremental area under the curve, mmol/L*min) at 1 hour by 21% (p < 0.001), incremental maximum concentration by 16% (p = < 0.001) and nocturnal glucose variation over the 14-day period. Participants on treatment reported improved sleep quality (Karolinska Sleepiness Scale, -0.17, p = 0.041) and feeling more relaxed (Brief Mood Introspection Scale, -0.4, p = 0.003) the next morning compared to when taking the control. Additionally, the treatment improved the vigor dimension on the Profile of Mood Scale (0.8, p = 0.038). No effects were observed on the cognitive performance. Lowering postprandial glucose significantly mediated the treatment effect of lowering sleep onset latency and lower nocturnal glucose variation was also associated with improved sleep quality and next-day positive mood. CONCLUSION: The evening meal supplement benefited sleep initiation and quality, and also improved post wake mood in adults.

Effect of Nutritional Supplements for Reducing Homocysteine Levels in Healthy Adults: A Systematic Review and Network Meta-Analysis of Randomized Trials. Liu C(1), Yao H(1), Wang F(1). Author information: (1)Department of Reproductive Medicine, The Second Hospital of Lanzhou University, Lanzhou City, Gansu Province, China. CONTEXT: There are various therapeutic approaches available to reduce homocysteine (Hcy) levels. However, it remains unclear which intervention is more effective for healthy adults. OBJECTIVES: A systematic review and network meta-analysis (NMA) were conducted to comprehensively investigate the efficacy of different nutritional supplements in reducing Hcy levels in healthy adults. DATA SOURCES: The PubMed, Embase, Cochrane Library, and Web of Science databases were searched from inception to July 2023. DATA EXTRACTION: The lead author, year of publication, sample size, population characteristics, intervention measures, duration, and mean difference of Hcy levels from baseline to endline were extracted. DATA ANALYSIS: Data were pooled using a random-effects model. Network meta-analysis was conducted by integrating direct and indirect evidence. A total of 16 studies were included in this analysis. The nutritional supplement combination that achieved the highest ranking (surface under the cumulative ranking curve [SUCRA] = 75.8) was superior compared with a single supplement. Among similar or closely dosed folic acid (FA) supplements, 800 μg FA (SUCRA = 93.7) was the most effective option. When comparing various doses of different supplements, 1 mg of FA plus 7.2 mg of vitamin B6 (B6) plus 20 μg of vitamin B12 (B12; SUCRA = 83.9) ranked first and 800 μg of FA (SUCRA = 78.3) ranked second. In comparison with placebo or no-treatment control groups, interventions such as 1 mg of FA plus 7.2 mg of B6 plus 20 μg of B12 (mean difference [MD] = -1.03; 95% CI -1.71 to -0.36), 400 μg of FA plus 400 μg of B12 (MD = -0.87; 95% CI -1.46 to -0.27), and 800 μg of FA (MD = -0.84; 95% CI -1.12 to -0.56) were more effective in reducing Hcy levels. The random-effects summary MD for all interventions compared with placebo was -0.59 (95% CI -0.71 to -0.48; P < .0001). CONCLUSIONS: The NMA demonstrated that the combination of FA with other vitamins is more effective in reducing Hcy levels, particularly when the dose of FA is close to 800 μg. The combination of 1 mg of FA, 7.2 mg of B6, and 20 μg of B12 is considered the most favorable option. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD42023453123. © The Author(s) 2025.

This study aimed to determine the dietary pyridoxine requirement of Pacific white shrimp (Penaeus vannamei) fed a soybean meal-based diet. Seven experimental diets were prepared with graded pyridoxine supplementation at 0, 25, 50, 75, 100, 125, and 150 mg/kg diet (Con, P25, P50, P75, P100, P125, and P150, respectively). An additional negative control diet (Con-) was formulated by adding 0.4% tetracycline hydrochloride to verify microbial synthesis of pyridoxine. Juvenile shrimp (initial weight: 0.38 g) were randomly assigned to eight diets with quadruplicate tanks and fed the diets for 45 days. Growth performance and feed utilization were increased with dietary pyridoxine supplementation up to P75, whereas higher supplementation levels resulted in reduced responses (P < 0.001). Hepatopancreas pyridoxine concentration was gradually increased with increment in dietary pyridoxine levels (P < 0.001), reaching a plateau from P75 to P150, and remained lower in Con- group than in Con group.

Vitamin B6 is an essential metabolite required by all living organisms and participates in numerous cellular biochemical reactions. Unlike mammals, plants can synthesize this compound de novo, and therefore, serve as an excellent nutritional source for the vitamin. Although the biosynthesis pathway in plants has been well understood for nearly two decades, the regulatory mechanisms that control vitamin B6 levels remain largely unknown. Here, we describe a novel set of Arabidopsis mutants that display distinct phenotypic and molecular characteristics and are likely affected in either the biosynthesis or homeostasis of vitamin B6. We propose that these new mutants will serve as valuable tools for uncovering the unknown regulatory steps governing vitamin B6 levels in plants. © 2026 The Author(s).

Rashid N(1), Yakkala VK(2), Syed SS(2), Rajagopalan K(2). Author information: (1)Medical Affairs, Acadia Pharmaceuticals Inc, San Diego, CA, USA. (2)Anlitiks Inc, Windermere, FL, USA. BACKGROUND: Trofinetide (TROF) remains the first and only FDA-approved pharmacologic treatment for Rett syndrome (RTT). There is limited real-world evidence on TROF use, restarts, dosing patterns and predictors of non-persistence. This study evaluated long-term treatment patterns and baseline predictors of non-persistence among RTT individuals initiating TROF. METHODS: A retrospective claims analysis of linked IQVIA Anonymized Patient Level Data and TROF pharmacy data (1 January 2021 to 30 September 2024) was performed. RTT individuals initiating 1st TROF prescription (RX) between 1 April 2023 and 31 March 2024 with ≥6 months of pre- and post-index continuous enrollment were classified as persistent (gap ≤90 days) and non-persistent. Median (IQR) time on treatment was analyzed, and Kaplan-Meier assessed time to non-persistence. Restarts among non-persistent were examined. Dosing patterns such as mean dose in milligrams (mg) and percentage target daily dose (%TDD) at each RX were evaluated. Predictors of non-persistence were assessed using logistic regression. RESULTS: Among 1,175 TROF initiators, 54.

Author information: (1)Paediatrics, East Sussex Healthcare NHS Trust, Saint Leonards-on-Sea, UK ahmed.osman34@nhs.net. (2)Paediatrics, East Sussex Healthcare NHS Trust, Saint Leonards-on-Sea, UK. Pyridoxine-dependent epilepsy (PDE) is a rare autosomal recessive metabolic epilepsy classically presenting with refractory neonatal seizures that respond to pharmacological doses of pyridoxine (vitamin B6). Although traditionally regarded as a neonatal disorder, later presentations are increasingly recognised. We report an adolescent patient with long-standing treatment-resistant epilepsy and learning disability who was ultimately diagnosed with PDE. Whole genome sequencing identified compound-heterozygous pathogenic variants in ALDH7A1 The diagnosis was further supported by elevated urinary and plasma α-aminoadipic semialdehyde levels. Initiation of pyridoxine therapy combined with lysine-reduction treatment resulted in sustained seizure control and allowed gradual withdrawal of conventional antiseizure medications. This case highlights the importance of considering PDE in older children and adolescents with refractory epilepsy and neurodevelopmental impairment and demonstrates the value of integrating genomic and metabolic investigations to establish a definitive diagnosis. © BMJ Publishing Group Lim

Author information: (1)Department of Urology, University of the Ryukyus, Kiyuna 1076, Ginowan-city, Okinawa, Japan. ryukyuogawa@gmail.com. For decades, the clinical management of urolithiasis has emphasized dietary oxalate restriction. However, this review synthesizes over 40 years of research demonstrating that endogenous production, driven by specific metabolic precursors, plays the dominant role in oxalogenesis. Utilizing acute and chronic rat models, we quantified the conversion of glyoxylate, glycolate, ethylene glycol, hydroxypyruvate, and hydroxyproline into urinary oxalate. These studies establish a clear hierarchy of lithogenicity, with glyoxylate and glycolate emerging as the most potent precursors. Importantly, we identify Vitamin B6 (pyridoxine) deficiency as a critical metabolic "gatekeeper" that markedly amplifies oxalate synthesis. Deficiency states were found to increase precursor-to-oxalate conversion rates by up to 25-fold by suppressing hepatic alanine-glyoxylate aminotransferase (AGT) activity. Collectively, these findings support a paradigm shift in stone prevention: moving beyond dietary oxalate restriction toward managing precursor load and optimizing Vitamin B6 status. © 2026.

(2)Centre for Nutrition and Food Sciences, University of Queensland, Brisbane, Queensland 4072, Australia. Vitamin B6 is an essential cofactor of numerous enzymes, and beer may contribute substantially to its dietary intake. While vitamin B6 occurs predominantly as glycosides in plants, data on the complete vitamer profile in beer remain scarce. Here, a novel SIDA LC-MS/MS method was developed for the native quantification of pyridoxine, pyridoxal, pyridoxamine, 4-pyridoxic acid, pyridoxine-5'-β-glucoside, pyridoxine-5'-β-maltoside, and pyridoxine-5-β-cellobioside. The method was validated for linearity, precision, recovery, and limits of quantification (0.20-12.9 μg/L) and detection. Analysis of 65 beers revealed total vitamin B6 concentrations ranging from 95.3 to 1020 μg/L, including multiple B6 glycosides. Variations in vitamin B6 composition were primarily associated with raw materials rather than with brewing technology. No significant differences were observed between alcohol-free and corresponding full-strength beers, whereas wheat b

Case report on Vitamin B6-Responsive Gyrate atrophy with Cystoid Macular Edema in a Consanguineous Young Male: A Treatable Metabolic Retinopathy. [Article in English, French; Abstract available in French from the publisher] Jagadish R(1), Giri N, Laturkar GR, Grover S, Trapasiya JK. Author information: (1)Department of Ophthalmology, Dr. D. Y. Patil Medical College, Hospital and Research Centre, Pune, Maharashtra, India. Gyrate atrophy is a rare autosomal recessive chorioretinal dystrophy caused by ornithine aminotransferase deficiency, resulting in toxic accumulation of plasma ornithine and progressive retinal degeneration. We describe a 20-year-old male, born to consanguineous parents, who presented with progressive diminution of vision, nyctalopia, and peripheral visual field loss. Fundus examination revealed sharply demarcated, scalloped areas of midperipheral chorioretinal atrophy with relative macular sparing. Optical coherence tomography demonstrated cystoid macular edema, whereas plasma ornithine levels were markedly elevated. The patient was treated with dietary protein restriction and pyridoxine supplementation, with biochemical improvement and stabilization of visual function. Early recognition, metabolic monitoring, and evaluation of pyridoxine responsiveness may delay visual deterioration and improve visual prognosis in gyrate atrophy. Publisher: RésuméL’atrophie

Author information: (1)School of Psychology and Clinical Language Sciences, The University of Reading, Reading, Berkshire, UK, reading.ac.uk. BACKGROUND: Several lines of evidence suggest that vitamin B6 has potential as an antidepressant. It plays a crucial coenzyme role in the synthesis of the neurotransmitters serotonin, gamma-aminobutyric acid (GABA) and dopamine, which are central to mood regulation, and it has been shown that increasing availably of vitamin B6 above normal levels increases concentrations of serotonin and GABA. Furthermore, epidemiological evidence points to vitamin B6 deficiency as a risk factor for depression, and to high vitamin B6 levels as protective. Therefore, we asked whether taking 100 mg vitamin B6 as pyridoxine daily for 1 month would reduce depression symptoms, measured with the Depression, Anxiety and Stress Scales (DASS) questionnaire, which also assesses anxiety and stress. METHODS: We recruited 267 participants from the general population (215 female) and double blind randomised them to receive either placebo, vitamin B6 or vitamin B12 (1000 µg). Using baseline DASS scores, we divided participants into a group classified as having mild or more severe depression symptoms at baseline (N = 58) and a larger group classified as non-depressed.

Pyridoxine/pyridoxal-5'-phosphate repletion to improve outcomes of alcohol withdrawal syndrome and promote long-term abstinence: a hypothesis. Weintraub SJ(1)(2). Author information: (1)Division of Hospital Medicine, Department of Medicine, Saint Louis VA Medical Center, Saint Louis, Missouri, USA. (2)Department of Internal Medicine, Washington University School of Medicine, Saint Louis, Missouri, USA. INTRODUCTION: Deficiency of pyridoxal-5'-phosphate, the clinically measured and active form of pyridoxine (vitamin B6), is prevalent among those with alcohol use disorder. However, unlike thiamine, pyridoxal-5'-phosphate is not routinely repleted. Evidence is presented that its repletion would improve outcomes of alcohol withdrawal syndrome and promote long-term abstinence. PYRIDOXAL-5′-PHOSPHATE DEFICIENCY CAN CAUSE A CLINICALLY CONSEQUENTIAL GLUTAMATERGIC/GABAERGIC SIGNALING IMBALANCE: Excessive excitatory glutamatergic signaling and inadequate inhibitory GABAergic signaling are central to the pathophysiology of alcohol withdrawal syndrome. Pyridoxal-5'-phosphate is an essential cofactor for the rate-limiting enzyme in the conversion of glutamate to GABA, glutamic acid decarboxylase. Therefore, pyridoxal-5'-phosphate deficiency would be expected to exacerbate the signaling imbalance that underlies alcohol withdrawal syndrome, worsening symptoms and treatmen

Vitamin B6 deficiency as a cause of erythropoietin-stimulating agent-resistant anemia in hemodialysis patients: A report of two cases.

(2)Department of Nephrology, Juntendo University Graduate School of Medicine, Japan. (3)Department of Cell Therapy and Transfusion Medicine, Juntendo University Graduate School of Medicine, Japan. Erythropoietin-stimulating agent-resistant anemia (ESA-RA) is observed in a significant number of hemodialysis (HD) patients. However, the underlying mechanisms remain unclear. We report two HD patients in whom vitamin B6 (VB6) deficiency was thought to be the cause of ESA-RA, and oral administration of pyridoxal phosphate hydrate led to prompt elevation of hemoglobin levels. VB6 is crucial for heme biosynthesis. HD removes VB6 from the serum. Therefore, patients undergoing HD are theoretically prone to VB6 deficiency anemia. However, reports of VB6 deficiency anemia in HD patients are scarce, and we speculate that this is an under-recognized cause of ESA-RA. DOI: 10.2169/internalmedicine.7782-26 PMID: 42438034

Author information: (1)Alexandria School of Medicine (2)Wilson Case Western University Vitamin B6 (pyridoxine) is an essential water-soluble vitamin that functions as a precursor to pyridoxal 5′-phosphate, a coenzyme involved in more than 100 enzymatic reactions related to amino acid, carbohydrate, and lipid metabolism, neurotransmitter synthesis, and numerous physiologic processes. Although vitamin B6 deficiency is uncommon, it may occur in association with certain medical conditions, medications, nutritional inadequacy, and inherited metabolic disorders. Pyridoxine also has important therapeutic applications in the management of vitamin B6–dependent syndromes, selected toxicologic emergencies, and pregnancy-associated nausea and vomiting. This activity reviews the pharmacology, clinical indications, dosing, administration, adverse effects, toxicity, monitoring, and drug interactions associated with vitamin B6. Participants will gain knowledge to identify deficiency and toxicity states, evaluate appropriate therapeutic uses, apply evidence-based monitoring and safety considerations, and collaborate effectively within the interprofessional healthcare team to optimize patient outcomes.

Buckner BA(1), Downs DM(1). Author information: (1)Department of Microbiology, University of Georgia, Athens, Georgia, USA. Pyridoxal 5'-phosphate (PLP) is a nutrient required by all life. As an essential cofactor, PLP powers enzymatic reactions in primary and secondary metabolism. Microbes can obtain PLP through either de novo PLP biosynthesis or the salvage of exogenous vitamin B6. Vitamin B6 exists in multiple forms (vitamers) in the natural environment, but the effect of mixed B6 vitamer supplementation on microbial physiology has not been explored. In this study, the ability of Salmonella enterica to obtain PLP during growth in media containing various ratios of B6 vitamers is examined. The data show that the B6 vitamer, pyridoxine (PN), can inhibit the salvage of B6 vitamers, pyridoxamine and pyridoxal, by S. enterica pdxH mutants. Genetic analyses were performed to determine the mechanism by which PN disrupts pyridoxamine and pyridoxal salvage. Mutants resistant to PN inhibition during the salvage of pyridoxamine were isolated and found to encode variants of B6 kinase (PdxK) with altered activity toward the B6 vitamer substrates. Suppressor analysis suggests that PN inhibition is, at least, partially due to competitive inhibition of the pyridoxamine kinase activity of PdxK by

Author information: (1)Garnet Health Medical Center Emergency Medicine Residency, Middletown, NY (2)St. Barnabas Health System (3)Jefferson-Einstein Healthcare Network (4)SUNY Upstate Medical University Isoniazid (INH) is a potent bactericidal antibiotic used to treat tuberculosis (TB). INH therapy carries a risk of acute or chronic toxicity. Acute toxicity manifests as neurological symptoms, specifically seizures. Consumption of as little as 2 g of INH can predispose a patient to acute toxicity. Patients with certain risk factors or prolonged INH use can develop chronic toxicity, which can manifest as hepatotoxicity and peripheral neuropathy. Two recognized syndromes of hepatotoxicity include: Mild hepatotoxicity, manifesting as transient, asymptomatic elevations in serum aminotransferase levels. Severe acute hepatitis, which can be fatal. Peripheral neuropathy is secondary to vitamin B6 (pyridoxine) deficiency, although its prevalence is relatively low.

A young adult female presented with recurrent sputum smear-positive pulmonary tuberculosis (TB) despite completing four prior courses of standard first-line anti-tubercular therapy. She presented with progressive breathlessness, productive cough and intermittent fever. Imaging revealed bilateral upper lobe fibrocavitary disease with cystic bronchiectasis. Repeated molecular testing confirmed Mycobacterium tuberculosis without rifampicin or isoniazid resistance. Therapeutic drug monitoring (TDM), though not routinely recommended in TB management, was undertaken in view of recurrent disease and showed undetectable rifampicin and subtherapeutic isoniazid concentrations, pointing towards impaired absorption or altered pharmacokinetics as the likely cause of recurrence. The patient was treated with a higher-dose fixed-dose combination regimen supplemented with pyridoxine, probiotics, vitamin D and nutritional support. After 6 months, she showed symptomatic improvement, weight gain, sputum conversion and reduced resp

Background/Objectives: Micronutrient deficiencies are common in inflammatory bowel disease (IBD) and contribute to anemia, impaired wound healing, neurologic injury, and adverse disease outcomes. Major societies, including ESPEN, ACG, and ECCO, recommend nutritional and micronutrient assessment in patients with IBD, yet few studies describe how comprehensively these recommendations are applied during hospitalization. This study aimed to characterize inpatient testing practices for vitamins B1, B6, B12, and zinc in hospitalized IBD patients

BACKGROUND: Acute alcohol intoxication (AAI) is a common emergency with no specific antidote. Metadoxine has shown potential but lacks sufficient real-world evidence, particularly in Chinese populations. OBJECTIVES: To evaluate the clinical efficacy and safety of metadoxine in patients with acute alcohol intoxication. METHODS: This single-center retrospective cohort study included 124 patients with AAI admitted to an emergency department between January and December 2024. Patients were divided into metadoxine plus conventional treatment (n=62) or conventional treatment alone (n=62) after propensity score matching. Primary outcomes were time to consciousness recovery (Glasgow Coma Scale ≥14) and treatment effectiveness rate (symptom improvement within 6 hours without treatment escalation). Secondary outcomes included time to symptom relief
