Glycine is an amino acid involved in everything from collagen and creatine production to muscle repair and antioxidant support. It also acts as a quietening signal in the brain, helping the nervous system settle and supporting the natural drop in core body temperature that tells your body it’s time to sleep.
Glycine is commonly taken around an hour before bed, helping to sharpen your nighttime routine. It may also help reduce next-day tiredness after a restless night, though it works best alongside the foundations of good sleep, not instead of them. Alongside this, glycine supplements support collagen formation, connective tissues and post-exercise recovery, making them a versatile addition to both sleep and performance stacks.
