Methionine is an essential, sulphur-containing amino acid, found in protein foods. Amino acids are the raw materials used by the body to manufacture human proteins, which are vital components of all human cells. Methionine is an antioxidant and detoxifier. It inhibits oxidation of low-density lipoprotein (LDL), which can cause plaque build-up and hardening of the arteries.
Signs of methionine deficiency include hair loss, edema, high cholesterol, and poor immune function. Meat, fish, dairy, beans, eggs, onions, garlic, and sunflower seeds are all natural sources of methionine.
Depending on body weight, daily requirements vary between 800-1,000 mg.
