PHOSPHATIDYLSERINE BOOSTS ANTIOXIDANT POTENTIAL AND MAY ENHANCE RUNNING PERFORMANCE

Phosphatidylserine (PS) is a natural component of many cell membranes. Supplementation with PS has been shown to reduce mental stress and even the stress response to exercise. Some research suggests that it may function as an antioxidant as well. A study published in the August issue of Medicine and Science in Sport and Exercise examined PS supplementation in soccer players. The subjects supplemented with PS (750 mg/day) or placebo for 10 days. Before and after the supplementation period, subjects performed an intense exercise protocol consisting of intermittent high-intensity activities for a total of 90 min culminating in a test to volitional fatigue as a measure of performance. The main effect of PS supplementation was to increase blood levels of gamma tocopherol, which could potentially augment antioxidant defense. There was also a trend for improved performance. Performance was increased by 4.2% with PS supplementation and decreased by 3.7% in the placebo group. The study provides evidence of an ergogenic effect of PS supplementation on exhaustive running.

any used this and what are your thoughts on it?

Is one of my favourite supp's. Definite positive effects on mental clarity and mood after just 3-5 days of use. Harder to say how it effects training performance though.

Have used and recommend the NOW Foods caps which contain 100mg Phosphatidyl Serine, 100mg Choline and 50mg Inositol per cap. Effective at the suggested dose of 3 caps daily.

cool you gotta link to where they sell those now food caps please mate

just found this on wikipedia didnt think there was so much of it in alot of foods not sure if its worth supplementting
