Does Betaine Endurance Performance Meta-Analysis work?

The current Migaku evidence database contains 2 reusable source documents for Betaine Endurance Performance Meta-Analysis. This answer focuses on strength of evidence and what the studies can or cannot prove. - The pooled results demonstrated that BET significantly improved endurance performance compared to control conditions, with a more pronounced effect under fatigued conditions (SMD = 0.87, 95% CI 0.61-1.13) than at baseline (SMD = 0.21, 95% CI 0.08-0.34). [Yu J (2026); evidence level 1] - This study systematically evaluated the effects of Brain Endurance Training (BET) on alleviating mental fatigue, enhancing endurance performance, and improving cognitive function through a systematic review and meta-analysis of nine peer-reviewed articles comprising 11 studies identified via a comprehensive database search following PRISMA 2020 guidelines. [Yu J (2026); evidence level 1] - While BFR reduces mechanical stress on joints, the associated metabolic stress and discomfort may limit training performance. [Zhao B (2026); evidence level 1] - Certain nutritional supplements may enhance BFR training effects, but the existing evidence remains inconclusive. [Zhao B (2026); evidence level 1] - Nutritional interventions were associated with improvements in muscular endurance (SMD = 0.90; 95% CI: 0.55, 1.25; p Conclusion Current evidence suggests that nutritional interventions may support fatigue resistance and enhance muscular endurance under BFR training conditions, but do not provide a clear additional benefit for maximal strength or hypertrophy. [Zhao B (2026); evidence level 1] 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.
