Glycine is a form of amino acid that is naturally produced by the body, however only in small amounts. Despite this, glycine plays a role in the transmission of chemical signals to and from the brain, and aids in the process of memory storage. It is also used in building proteins.
The Recommended Dietary Allowance (RDA) for the group of proteins that glycine falls under is 0.8 g per kilogram of your total body weight. Average-size adults will need at least 60 g of glycine. The typical human diet contains as little as 2 g of glycine, so it is important to include these 12 foods high in glycine to your diet:
1. Unsweetened Gelatin
The average serving of powdered and unsweetened gelatin contains 1.333 grams of glycine, whereas larger scoops will give you up to 19.049 g. Among all food groups, this is considered as the best provider of not just glycine, but of proteins in general. Gelatin is made from animal parts like collagen, which is an excellent source of amino acids.
