Serine is a non essential amino acid needed for the metabolism of fats and fatty acids, muscle growth, and to maintain a healthy immune system- as it aids the production of immunoglobulins and antibodies. It also plays an important role in the manufacture of cell membranes, and the synthesis of both muscle tissue and the sheath that surrounds nerve cells. Serine can be obtained from beans, brewer’s yeast, dairy products, eggs, fish, lactalbumin, legumes, meat, nuts, sea food, soy, whey and whole grains. When necessary, the bosy can synthesize serine from amino acid glycine.

Phosphatidylserine (PS) is a compound made by the body. Supplemental PS is widely used in Italy, Sacndinavia, and other parts of Europe to treat various forms of age-related dementia as well as normal age-related memory loss.

PS supplements increase the cerebral cortex’s output of the neurotransmitter acetycholine, which is associated with thought, reasoning, and concentration. PS also stimulates the synthesis and release of dopamine. PS also appears to be associated with the brain’s response to stress. Stress response can be determined by measuring blood ACTH levels. ACTH is a hormone secreted by the pituitary gland, which in turn promoted the adrenal glands to secrete the stress hormone cortisol.
