Is Alpha Gpc Power Performance Randomized Trial safe?

Updated October 2026

Quick Answer

Alpha Gpc Power Performance 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: Background Nutrition plays a key role in training and athletic performance and dietary supplements can make a small, but potentially valuable, contribution to achieving peak athletic performance.

Key Takeaways

  • 01Background Nutrition plays a key role in training and athletic performance and dietary supplements can make a small, but potentially valuable, contribution to achieving peak athletic performance. [Harrington RN (2023)]
  • 02This study is the first to investigate the effects of supplementation from the combination of BCAAs, L-citrulline, and A-GPC on exercise performance. [Harrington RN (2023)]
  • 03Serum free choline was found to be elevated in the two A-GPC groups as compared to placebo (132% and 59% respectively). [Marcus L (2017)]
  • 04Serum TSH was found to be significantly depressed in the 500 mg A-GPC group compared to other treatments ( p p Conclusions Based upon this evidence, and previous evidence regarding A-GPC, it should be considered as an emerging ergogenic supplement. [Marcus L (2017)]
The current Migaku evidence database contains 2 reusable source documents for Alpha Gpc Power Performance Randomized Trial. This answer focuses on safety, limits, and clinician-discussion contexts. - Background Nutrition plays a key role in training and athletic performance and dietary supplements can make a small, but potentially valuable, contribution to achieving peak athletic performance.

[Marcus L (2017); evidence level 4] - Serum TSH was found to be significantly depressed in the 500 mg A-GPC group compared to other treatments ( p p Conclusions Based upon this evidence, and previous evidence regarding A-GPC, it should be considered as an emerging ergogenic supplement. [Marcus L (2017); evidence level 4] - Background Recent studies have suggested that alpha glycerylphosphorylcholine (A-GPC) may be an effective ergogenic aid. [Marcus L (2017); 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.
