Phosphatidyl serine or "PS" is a concentrated source of nutritious fats known as phospholipids. Phospholipids provide critical structural, physiological and biochemical support to cell membranes throughout the body, but are particularly for the brain.
Phosphatidyl serine supplements are used as brain boosters, to improve memory and concentration, especially in the elderly. PS may also be able to lower levels of the catabolic stress hormone cortisol.
Use as directed. Phosphatidyl Serine can also be combined with other brain boosters like ginkgo biloba and acetyl-l-carnitine
