Glycine is one of the three amino acids the body uses to synthesise its own creatine, and it's also the most abundant amino acid in collagen. Beyond its role in creatine production, glycine has been studied for its effect on sleep quality and recovery.

About
Glycine is the simplest amino acid and one the body can produce on its own, though supplementation increases the amount available for its various functions. Alongside arginine and methionine, it's a direct building block in the body's endogenous creatine production. It's also the most abundant amino acid in collagen, the structural protein found in connective tissue, skin and tendons.
A growing body of research points to glycine's effect on sleep. Trials have found that glycine taken before bed can improve subjective sleep quality and reduce daytime sleepiness, an effect thought to be linked to glycine's role in lowering core body temperature, one of the physiological triggers for sleep onset.
Reviews of the evidence have also flagged glycine's potential to support peak power output and reduce lactic acid build-up during high intensity effort, alongside its established role in recovery.
