Phosphatidyl serine softgels, provided by Douglas Laboratories® contain 500 mg of plant-derived (soy bean) phospholipids supplying 100 mg of phosphatidyl serine (PS). Until recently, PS was only available as a very expensive product derived from bovine sources, with microbiological safety problems. New technology has made it possible to concentrate this important brain nutrient from soy bean lecithin, a safe and well-recognized source of phosphatidyl serine.
