Adenosine 5'-triphosphate disodium (ATP) is the primary energy carrier in all living cells and is crucial for muscle contraction and relaxation processes. Its role in cellular energy metabolism is well-established in physiology. Some scientific research has investigated the effects of exogenous ATP administration (oral, intravenous, or intramuscular) on muscle function, fatigue, and tone, particularly in clinical settings addressing muscle weakness or hypotonia (lack of muscle tone). However, the evidence supporting ATP supplementation for improving muscle tone in humans remains limited and mixed.

A few small-scale clinical trials and animal studies have suggested that supplemental ATP might help enhance muscle strength, reduce fatigue, or support muscle recovery by increasing local energy availability or improving blood flow. For example, studies in athletes have examined oral ATP supplementation and found modest improvements in muscle performance or reduced fatigue, but these effects are not consistently replicated, and most research focuses on performance enhancement rather than treating medical hypotonia.

Importantly, ATP administered orally is rapidly degraded in the gastrointestinal tract, limiting its systemic bioavailability. Thus, the direct effect of supplemental ATP on muscle tone is questionable. No high-quality, large-scale clinical trials have demonstrated a significant or reliable benefit of ATP supplementation for treating lack of muscle tone (hypotonia) in clinical populations. In summary, while the scientific rationale is grounded in ATP's role in muscle physiology, current evidence supporting its clinical use for lack of muscle tone is weak, and more robust research is needed.
