In plain language

What it does in your body

Choline is an essential (vitamin-like) nutrient the body cannot produce in sufficient quantities.

Choline contributes to normal lipid metabolism and to normal liver function — authorized health claims (EFSA).

As a component of phosphatidylcholine, it takes part in building cell membranes.

Natural source:

Choline is an essential nutrient found in eggs, liver, soy and fish. The body produces small amounts, but not enough for optimal function. Choline bitartrate is a stable, water-soluble form — ideal for sachets.
