Serine is a non-essential amino acid, which means it can be both synthesised in the body and obtained from food. Serine can be synthesised from another nonessential amino acid, glycine. Its production requires adequate amounts of Vitamin B3, B6 and folic acid. The body uses serine to form cell membranes, nerve coatings and to synthesize creatine. It is also important for the metabolism of RNA and DNA.

 

Serine can be found in soy products, dairy products, gluten, peanuts and meats.
