Home -> Shop By Store -> PhosphatidylserinePhosphatidylserineWhat is Phosphatidylserine(PS)?Phosphatidylserine, or PS, is a naturally occurring, phospholipid nutrient. PS is essential to the functioning of all the cells of the body, but is most concentrated in the brain. Phosphatidylserine relative abundance in this organ reflects its proven involvement in an assortment of nerve cell functions, including nerve transmitter release and synaptic activity. Clinical studies have suggested that Phosphatidylserine (PS) can support brain functions that tend to decline with age. Until recently, Phosphatidylserine (PS) was only available from animal sources (brain), and occurred in commercial lecithins only in trace amounts; however, a plant source for Phosphatidylserine (PS) has now been developed. This remarkable nutrient called Phosphatidylserine (PS) is extracted from soy, and it is 100% natural. Phosphatidylserine is a naturally occurring phospholipid compound, which has been shown to improve the memory and cognition in the healthy as well as in the mentally deteriorated elderly. Phosphatidylserine is made up of a glycerophosphate skeleton linked to two fatty acid molecules and the amino acid L-serine. It is an amphiphilic molecule because it is made up of the lipophilic fatty acid tails on one side and the hydrophilic head group containing phosphate and serine on the other side of the molecule. Phosphatidylserine is located in the internal layers of biologic membranes, facing the cytoplasm with its polar head group. In animal tissues, phosphatidylserine is formed from phosphatidylethanolamine by exchange of the ethanolamine head for L-serine. Phosphatidylethanolamine itself is synthesized from diacylglycerol and CDP-ethanolamine. Uses of Phosphatidylserine: Phosphatidylserine support brain function that tend to decline at age. Brain function includs learning and memory of names and faces, remembering the location of scattered objects, Maintain the concentration, recall telephone numbers, recall events and details. General Information: Phosphatidylserine was discovered in 1941, and it has been studied extensively ever since. Today, there are more than 7.560 scientific publications on this substance in the MEDLINE database, 37 of which relate to its effect on the memory. Phosphatidylserine is an integral part of all cell membranes of the body, most concentrated in the brain. In the brain Phosphatidylserine protects the hippocampus (a major memory center) from the loss of nerve cell dendrite connections that normally occurs with ageing. Phosphatidylserine Side Effects: Ingested Phosphatidylserine is readily absorbed in the blood and transported to the brain. Normal dosing of Phosphatidylserine supplements neither causes any side-effects nor interferes adversely with any prescribed medication. |
