Phosphatidyl serine (PS) is a phospholipid nutrient found in fish, green leafy vegetables, soybeans and rice, and is necessary for the optimal functioning of neuronal cell membranes, (PS) also activates protein kinase which has been shown to be involved in memory function. Cell membranes not only act as a barrier between the inside and outside of a cell, but also play an important role in cellular communication and normal cellular responses. Phosphatidyl serine has also been documented to increase the availability of choline for synthesis of acetylcholine, an important neurotransmitter involved in memory and learning. It may also help enhance cognitive function by maintaining cholinergic activity in the brain. Phosphatidyl serine has demonstrated some usefulness in treating cognitive impairment, including Alzheimer’s disease, age-associated memory impairment and some non-Alzheimer’s dementias. (PS) has been suggested to support improved immune function and the reduction of exercise stress.
