Liposomes are designed not only to protect the nutritional supplement from degrading and absorbing in the harsh environment of the gut terrain but also to deliver the nutrients in a targeted manner to specific tissues and areas of the body.*All natural phosphatidylcholine is classified as lecithin, which is a description of purification rather than a material identification. We use natural non-hydrogenated sunflower phosphatidylcholine in our manufacturing process, derived from non-GMO certified sunflower oil from Europe. The liposomes are the optimal size for absorption, as small as 50 nanometers. We use no soy ingredients, and our flavors are completely natural. Our liposomes are naturally non-gluten, alcohol-free, vegan, and made of non-GMO ingredients.
