Choline 1 article

Compounds such as phosphatidylcholine and acetylcholine place choline in a distinctive role among essential nutrients. Egg yolk and liver are concentrated food sources, while soy-derived phosphatidylcholine and forms such as choline bitartrate appear in supplements and fortified products. Supplement labels may also feature related ingredients such as citicoline or alpha-GPC, but those names should not be treated as synonyms for total choline; the declared choline contribution depends on the specific compound and formulation.
