Natural Factors PS are a potent source of PS, which is important for nerve cell membranes and brings new life to all nerve cell activities. PS, part of a unique group of fat-soluble nutrients called phospholipids, is located in every cell membrane but is available in the largest percentages within brain cells. PS benefits a majority of individuals since we are all subject to free radicals formed from breathing cigarette smoke, drinking alcohol, being surrounded by pollution, or being subjected to chronic emotional stress. These stressors have adverse effects on the health of the human brain.
Natural Factors PS come from soy phospholipids. Clinical research with plant-based PS demonstrates the same efficacy rates as animal-based PS without contamination concerns regarding prion diseases such as Mad Cow. Research has verified that PS is safe for the human body.
PS can also affect moods. A double-blind study on elderly women demonstrated that PS assisted both memory and behavior. The brain normally manufactures enough phosphatidylserine, but evidence points to the idea that the elderly, who do not get enough phosphatidylserine, may have a higher chance of depression and/or impaired mental functions. Numerous double-blind studies where the subjects supplement with phosphatidylserine have demonstrated improved mental functions, mood, and behavior, even for individuals in the early stages of Alzheimer’s and Parkinson’s. Typical antidepressant drugs influence serotonin and neurotransmitters, but PS has other mechanisms of action like a decrease in the secretion of cortisol, the stress hormone.
