Is Betaine Fatigue Meta-Analysis safe?

The current Migaku evidence database contains 2 reusable source documents for Betaine Fatigue Meta-Analysis. This answer focuses on safety, limits, and clinician-discussion contexts. - 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] - Despite the theoretical appeal of this combined strategy, empirical evidence remains inconsistent. [Zhao Bingran (2026); evidence level 1] - This study seeks to clarify the specific application value of nutritional supplements within the BFR training framework and explore the underlying physiological mechanisms, thereby providing evidence-based recommendations for the development of more precise, personalized training and nutrition strategies. [Zhao Bingran (2026); evidence level 1] - 18 The risk of bias of the included randomized controlled trials was independently assessed by two researchers (B.R.Z. [Zhao Bingran (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.
