Is Vitamin B6 Exercise Fatigue Randomized Trial safe?

Updated October 2026

Quick Answer

Vitamin B6 Exercise Fatigue Randomized Trial has evidence relevant to safety, limits, and clinician-discussion contexts, but conclusions should stay close to the cited sources. One representative finding is: Based on the evidence presented above, we hypothesized that a 28-day supplementation of vitamin B would enhance physical performance and reduce physical fatigue.

Key Takeaways

  • 01Based on the evidence presented above, we hypothesized that a 28-day supplementation of vitamin B would enhance physical performance and reduce physical fatigue. [Lee MC (2023)]
  • 02After supplementation with Ex PLUS ® , we found a significant increase in the running time by 1.26-fold ( p 0.05) to exhaustion compared to that before supplementation and that in the placebo group. [Lee MC (2023)]
  • 03In addition, the Ex PLUS ® supplementation group presented significantly reduced blood lactate and blood ammonia concentrations during exercise and at rest after exercise compared with placebo ( p ® ) supplementation significantly improved exercise endurance performance and reduced exercise fatigue biochemical metabolites in not athletes. [Lee MC (2023)]
  • 04B vitamins play a crucial role in maintaining fundamental cellular functions and various essential metabolic pathways in the body. [Lee MC (2023)]
The current Migaku evidence database contains 2 reusable source documents for Vitamin B6 Exercise Fatigue Randomized Trial. This answer focuses on safety, limits, and clinician-discussion contexts. - Based on the evidence presented above, we hypothesized that a 28-day supplementation of vitamin B would enhance physical performance and reduce physical fatigue. [Lee MC (2023); evidence level 2] - After supplementation with Ex PLUS ® , we found a significant increase in the running time by 1.26-fold ( p 0.05) to exhaustion compared to that before supplementation and that in the placebo group. [Lee MC (2023); evidence level 2] - In addition, the Ex PLUS ® supplementation group presented significantly reduced blood lactate and blood ammonia concentrations during exercise and at rest after exercise compared with placebo ( p ® ) supplementation significantly improved exercise endurance performance and reduced exercise fatigue biochemical metabolites in not athletes. [Lee MC (2023); evidence level 2] - B vitamins play a crucial role in maintaining fundamental cellular functions and various essential metabolic pathways in the body. [Lee MC (2023); evidence level 2] - Conclusion: The change of hypoxanthine concentration in sweat can be used as a good biomarker for the diagnosis of exercise-induced fatigue, while the change of pyruvate content in sweat can be used as a discriminant index for the energy metabolism mode of the body before and after exercise. [Meihua S (2023); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational. People with medical conditions, pregnancy, medication use, or unusual symptoms should ask a qualified clinician before changing supplements, medication, or treatment routines.
