Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Guanidinoacetic acid (GAA) is investigated as an athletic and exercise aid primarily due to its role as a direct precursor to creatine, a well-established ergogenic compound. Scientific studies have shown that oral supplementation with GAA increases serum and muscle creatine levels, potentially leading to improved exercise performance, strength, and muscle mass—effects commonly associated with creatine supplementation. Randomized controlled trials and pilot studies have demonstrated that GAA may enhance muscle strength and anaerobic performance in both healthy individuals and athletes, though the body of evidence is modest and not as extensive as that for creatine itself.

For example, a systematic review published in 2019 highlighted that GAA supplementation can increase intramuscular creatine stores and, in some cases, improve measures of muscular strength and power. However, the magnitude of these benefits appears to be similar to, or slightly less than, those observed with direct creatine supplementation. Concerns remain about dosing, long-term safety (notably potential increases in homocysteine levels), and the optimal population for use. Despite these limitations, the mechanistic rationale and preliminary human studies provide scientific validation for the use of GAA as an exercise aid, though more robust and long-term clinical trials are needed to confirm efficacy and safety.
