Serine is an amino acid required for the synthesis of many proteins in our body. It plays an important role in many metabolic pathways and also acts as a precursor to several other amino acids. L-serine is a natural form of serine, and D-serine is another isomer that is synthesized in the body from L-serine. Although classified as a non-essential amino acid, Serine is not synthesized in our bodies in sufficient quantities and therefore it is important to ingest it through diet and supplementation.
