Nutricost Glycine Powder 3g
by Nutricost
"Pure glycine powder for sleep quality, collagen synthesis, and cognitive function at bulk pricing"
Overview
Nutricost Glycine Powder provides 3g of pure glycine per serving — the simplest amino acid that plays outsized roles in sleep, collagen synthesis, and neurotransmission. Glycine taken before bed (3g) has been shown in clinical studies to improve subjective sleep quality, reduce daytime sleepiness, and improve cognitive performance the next day. It's also a key component of collagen (making up about 1/3 of collagen's amino acid content) and acts as an inhibitory neurotransmitter in the brain. At 167 servings per bag, Nutricost delivers exceptional value for this versatile amino acid.
