Choline

Choline is a water-soluble essential nutrient that was long associated with the B-vitamin family before being classified in its own category. The body synthesises it in small amounts, but dietary intake — or supplementation — is still required to meet daily needs. It is naturally found in eggs, meat, fish and certain legumes. Choline plays a central role in several physiological processes. It is a precursor of acetylcholine, a neurotransmitter involved in memory and muscle coordination, and is a key component of membrane phospholipids, thus contributing to cell integrity. It also participates in hepatic lipid metabolism, helping to support normal fat transport in the liver. Choline intakes may be insufficient in certain populations — vegetarians, pregnant women, athletes — due to increased requirements or a poorly varied diet. Supplementation can therefore help contribute to adequate intakes, particularly to support cognitive function and normal lipid metabolism.
