Phosphatidyl Serine Complex More recent research has found another of lecithins phophatides to be very beneficial. Phosphatidylserine (PS) is found in very small amounts (that’s why it’s not on other lecithin labels). Our Leci-PS is 20% PS, which means for every 500mg capsule of Leci-PS complex there is 100mg of straight PS and 400mg of the remaining fatty acid complex. This is clearly listed on the label. Most of the studies done on PS for dementia, Alzheimer’s, and other brain related issues used, on average, 300mg of PS. These studies used PS derived from cow brain tissue and with the worry of “mad cow” disease; PS derived from soy is the preferred source. Leci-PS is a premier source from Lucas Meyer, known for their research and development in soy products.
