Glycine

Glycine supplementation improves sleep quality and reduces next-day fatigue in healthy individuals by enhancing sleep efficiency and promoting relaxation.

In a randomized double-blind trial, GlyNAC (glycine plus N-acetylcysteine) supplementation for 16 weeks improved muscle strength, gait speed, exercise capacity, and reduced fatigue in older adults, with benefits attributed partly to glycine.

Human studies indicate that 3g of glycine before bedtime improves sleep quality, reduces daytime sleepiness, and alleviates fatigue from acute sleep deprivation in healthy subjects.

A small double-blind study showed glycine improves long-term blood sugar control in healthy individuals at risk for metabolic issues.
