GlyNAC Reversed 9 Hallmarks of Aging in Humans

A Baylor University trial found that GlyNAC supplementation (glycine + N-acetylcysteine) reversed multiple aging hallmarks in humans. The trial reported reversal of 9 of the 12 classical hallmarks of aging, including oxidative stress, mitochondrial dysfunction, and inflammation. This is notable because GlyNAC is a simple, inexpensive combination of two amino acids, not a proprietary compound. The mechanism involves glutathione replenishment, as N-acetylcysteine is a precursor to glutathione, the body's primär endogenous antioxidant. The study was led by Dr. Premkumar Pugalenthi at Baylor. The sample size and duration were not fully specified in the source material. This is one of the few human trials to directly measure aging hallmarks as endpoints rather than clinical outcomes. The finding that a low-cost intervention can reverse aging hallmarks has significant implications for supplement accessibility.
