Phosphatidylcholine
A major phospholipid that forms cell membranes and supports liver and brain health.
Also known as: PC • Lecithin Phospholipid
Overview
Phosphatidylcholine (PC) is the most abundant phospholipid in cell membranes, making up 40-60% of the lipid bilayer. It is essential for cell structure, signaling, and repair. PC also serves as a source of choline for acetylcholine synthesis and supports liver function by facilitating fat metabolism and bile production.
