Phosphatidylserine (PS) covers and protects the cells in your brain and carries messages between them. It plays an important role in keeping your mind and memory sharp. As we age, PS levels naturally decline. Supplementing PS (often derived from soy or sunflower lecithin) is a key strategy in premium cognitive formulas to combat age-related cognitive decline.
Clinical Summary
Clinical trials demonstrate that PS supplementation can improve cognitive function, specifically short-term memory and mood, in the elderly. It also shows promise in blunting the cortisol spike associated with intense physical stress.
