Serine is a non-essential amino acid derived from the amino acid glycine. It is important to overall good health, both physical and mental. Serine is especially important to proper functioning of the brain and central nervous system.


What it is

Serine is central to the production of the myelin sheath that protects nerve cells as they speed nerve impulses through the brain and spinal cord. Deficiencies cause interference in the nerve impulses that supply information to and from the brain.

Serine also plays a role in the production of tryptophan, an amino acid that aids in the production of serotonin. Deficiencies in serotonin and tryptophan have been associated with depression, insomnia, confusion and anxiety, chronic fatigue syndrome and fibromyalgia.


What it does

Serine is needed for the proper metabolism of fats and fatty acids, the growth of muscle, and the maintenance of a healthy immune system. It is a component of the protective myelin sheaths that cover nerve fibers. It is important in RNA & DNA function and cell formation. Serine aids in the production of immunoglobulins and antibodies.
