A simple amino acid with power.
Glycine is the smallest amino acid in the body, yet it plays outsized roles. It makes up roughly one-third of collagen, the structural protein that supports skin, joints, tendons and connective tissue. It is also a building block of glutathione, the body’s primary antioxidant, and it supports calm, restorative sleep.
Research shows that taking glycine before bed can improve sleep quality, shorten the time it takes to fall asleep, and leave people feeling more alert the next day, all without the heavy sedation of many sleep aids. It works in part by gently lowering core body temperature, helping the body settle into deeper rest.
