Glycine is a simple, nonessential amino acid that slips into many everyday body functions. This form is L-Glycine housed in vegan capsules with a small amount of inulin as a minor part. Glycine helps sleep quality when taken before bed and supports antioxidant defences by acting as a precursor to glutathione. It also helps regulate blood sugar as part of normal metabolism. This supplement isn’t meant to diagnose, treat, cure, or prevent any disease.
