Phosphatidylcholine (PC) is one of the most important nutrients for promoting liver health, assisting with nutrient assimilation, hormone balance, brain function, and detoxification.* It is the basic building block of the membranes of every cell in the body. Research shows that supplemental PC, which is derived from lecithin, is highly bioavailable, as it is nearly 90% absorbed by the body.* PC supports fat emulsification and the absorption of fat-soluble vitamins. Due to its role in acetylcholine production, PC promotes healthy brain function and cognitive health.
