Arginine silicate is a compound composed of the amino acid L-arginine and silicon, often marketed for its potential benefits in supporting muscle and vascular health. The rationale for its use in the muscle body system primarily centers on the role of L-arginine as a precursor to nitric oxide (NO), a molecule involved in vasodilation and blood flow regulation. Enhanced blood flow is theorized to support nutrient and oxygen delivery to muscles during exercise, potentially aiding performance and recovery. A few small-scale clinical studies have examined arginine silicate (often in the form of arginine silicate inositol, or ASI), suggesting that it can increase plasma arginine levels and, in some cases, enhance markers of muscle pump and perceived performance during resistance exercise. However, evidence remains limited, with most studies involving relatively small sample sizes, short durations, and sometimes lacking rigorous controls. Reviews highlight that while arginine supplementation may improve blood flow, the magnitude of effect on muscle function or growth is modest and not consistently demonstrated. There is little tradition of arginine silicate use specifically for muscle support; its use is driven by recent scientific interest rather than historical precedent. In summary, while there is some scientific basis for arginine silicate’s role in supporting muscle function via increased nitric oxide production, the evidence is moderate at best, warranting a rating of 2 out of 5.
