Phosphatidylserine (PS) belongs to a special category of fat-soluble substances called phospholipids, which is an essential components of cell membranes and helps maintain cell membrane integrity and youthful synaptic plasticity, helps protect brain cells against the functional deterioration that occurs as a result of aging. Over 30 studies suggest that 200-300 mg per day of PS may help improve memory.
 
Published research in Europe has indicated PS could slow and even reverse the rate of brain cell aging in laboratory animals. PS restored mental function in older animals to levels exceeding those found in some younger animals. Although studies in humans with Alzheimer’s disease were less dramatic, they still produced significant improvements in cognitive function. In patients with mild dementia, significant cognitive and behavioral enhancing effects were observed. Most studies have used a standardized PS that provides an elemental level of 100 mg taken twice per day.
 
Brain tissues are especially rich in PS, but aging causes a decline in the PS content of cells throughout the body. Research has shown that in addition to improving neural function, PS enhances energy metabolism in all cells.
 
“PS Brain” promotes brain function by increasing neuronal membrane fluidity (cell-to-cell communication), resulting in improved cognition. Also, “PS Brain” protects against stress by mitigating the actions of cortisol (catabolic stress hormone.)
