Why Glycine for Skin

Glycine plays a supporting role in skin. Glycine is a non-essential amino acid. Supplemental glycine (often ~3 g taken before bed) has been studied for sleep quality and next-day fatigue in small trials.

What dose to look for

Clinical studies typically use 3–5 g of glycine. Common supplemental range; 3 g before bedtime has been used in small human sleep studies. Products below this range may not deliver meaningful results.

What the research says

Glycine has moderate clinical evidence for skin benefits. A few small trials on sleep quality at 3g before bed; well-tolerated but limited study sizes Learn more
