While the anti-aging implications have not been studied directly in humans, the mechanistic pathway is well-established and suggests potential benefits for anti-aging applications

Alternatively, a conventional spectrophotometric approach is frequently employed, which is based on the oxidation of GSH by 5,5-dithio-bis(2-nitrobenzoic acid) (DTNB) to a yellow derivative known as 5-thio-2-nitrobenzoic acid (TNB)

This does not mean long-standing hair loss cannot improve, simply that expectations should adjust accordingly

Future studies are warranted to determine effects of dietary glycine supplementation on muscle protein turnover and its associated regulatory pathways, as well as the molecular regulation of the expression of genes for GSH and creatine syntheses at transcriptional and translational levels

It is a plausible but unconfirmed benefit
