BodyBio PC is not a vitamin, but rather a potent combination of phospholipids, with the dominant one being Phosphatidylcholine, an integral component of our cell membranes. This combination is created through a distinct proprietary extraction process, forming a pure phospholipid complex which naturally assembles into liposomes in the body. It's important to note that non-liposomal PC, when subjected to the digestion process, wouldn't yield the same beneficial effects.
