Glycine (l-Glycine) is a non-essential amino acid which is made in the body from serine and theonine and is needed for protein synthesis and glucose metabolism. It is also found in meat, fish and dairy products. Glycine is present in considerable amounts in prostate fluid and plays a part in prostate health. It is required for the formation of creatine, which is needed for muscle function.

Common food sources of glycine are pork, chicken, lamb, turkey, soybeans, crab, beef and crayfish.

What it does

  1. Calming Agent: Glycine has an inhibitory effect on various neurotransmitters in the brain and may be beneficial as a calming agent.
  2. Anti-Convulsive and Anti-Spasmodic: A deficiency of glycine results in over-excitability of nerve cells leading to poor motor control and seizures. This can result in jerky, exaggerated movements and sometimes even spasticity.
  3. Connective Tissue Support: Collagen is an important structural protein in the body made up of chains of amino acids, with glycine, proline and hydroxyproline being the most common. Glycine may be of value in promoting the health and integrity of connective tissue and improving wound healing.
  4. Liver Support: Glycine is required for the detoxification of a variety of toxins in the liver.
  5. Antacid: Glycine has been shown to buffer excessive stomach acidity.
