Phosphatidylserine provides a pure source of this important phospholipid needed for the support and maintenance of mental performance and memory function. Low levels of phosphatidylserine in the brain have been associated with impaired mental function and depression, especially in the elderly. Supplementation of phosphatidylserine helps to release acetylcholine in the brain, significantly improving memory retention. Phosphatidylserine is indicated for age-related brain changes, such as dementia, Alzheimers disease, memory loss, senility and depression. The capsules in this formula are from a vegetable source making it suitable for vegetarians and vegans.
