Serine is required for

Serine is required for the metabolism of fat, tissue growth and the immune system as it assists in the production of immunoglobulins and antibodies. Some derivatives (e.g. ethanolamine) are also important components of the phospholipids found in biological membranes.

It is a constituent of brain proteins and nerve coverings and is also important in the formation of cell membranes, involved in the metabolism of purines and pyrimidines, and muscle synthesis. It is also used in cosmetics as a skin moisturizer.

Toxicity and symptoms of high intake

Although toxicity has not been established it has been found that very elevated serine levels may cause immune suppression and psychological symptoms as in cerebral allergies.

Best used with

Its production requires adequate amounts of vitamin B3 (niacin), B-6, and folic acid.

Food sources of serine

It is found in meats and dairy products, wheat gluten, peanuts as well as soy products.
