Choline is an essential nutrient that we must consume in our diet as the body cannot manufacture enough on its own for our daily needs. (The liver makes small amounts of choline that need to be topped up by our diet.)
A relatively recent discovery, choline is neither a vitamin nor a mineral, but it is similar in nature and necessity to the B vitamins. The body requires choline to help support a healthy liver, brain and nervous system and also to help regulate muscle movement and metabolism. It also plays a role in the production of new cell membranes and DNA molecules.
Choline is found abundantly in liver and eggs, but is also found in fish (in particular cod and salmon), cauliflower, broccoli and soya products to a lesser extent.
