The Details
Why you'll love it
Glycine is proof that simple molecules can do extraordinary things. This tiny amino acid — the smallest of the 20 — plays an outsized role in sleep, beauty, and detoxification.
Let's start with sleep. Research shows that glycine taken before bed lowers core body temperature and promotes faster sleep onset. A landmark Japanese study found that 3g of glycine before bed significantly improved subjective sleep quality, reduced daytime sleepiness, and improved cognitive performance the next day. Unlike melatonin, glycine doesn't make you groggy — it works by helping your body temperature drop naturally, which is the physiological trigger for sleep.
Glycine is also essential for collagen production. It makes up roughly one-third of all collagen in your body, so adequate glycine intake directly supports skin elasticity, joint health, and connective tissue repair. And it doesn't stop there — glycine is a precursor to glutathione (your master antioxidant) and supports a calm nervous system by acting as an inhibitory neurotransmitter in the brainstem.
