“Choline is crucial for sustaining life. It modulates the basic signaling processes within cells, is a structured element in membranes, and is vital during critical periods in brain development” [1]. It was discovered in 1862, yet it was not recognized as a required nutrient for humans until 1998 [1]. “Choline
has several important functions: it is a source of methyl groups
needed to make S-adenosylmethionine, it is a part of the
neurotransmitter acetylcholine, and it is a part of the predominant
phospholipids in membranes (phosphatidylcholine and
sphingomeyelin). Betaine, formed from choline, is an important
osmolyte in the kidney glomerulus and helps with the reabsorption of
water from the kidney tubule. Although they represent a smaller
proportion of the total choline pool, important metabolites of choline
include platelet-activating factor, choline plasmalogens,
lysophosphatidylcholine, phosphocholine, and glycerophosphocholine” [1]. “Healthy humans with normal folate and vitamin B12 status who were fed a choline-deficient diet developed liver damage…a diet deficient in choline has major consequences including hepatic, renal, pancreatic, memory, and growth disorders…Large amounts of lipids (mainly triglycerides) can accumulate in the liver…Choline deficiency causes cancer in rodent models” [1]. Some
have claimed that choline is vitamin B-4 and is helpful for
cardiovascular health [4]. Yet while there are cardiovascular
benefits associated with food choline, it appears that what was once
called vitamin B-4 was probably more accurately a substance known as
adenine [5], which is not choline. Both adenine and choline play
a role in ATP metabolism [1], and choline can have cardiovascular
benefits, but calling it vitamin B-4 seems inaccurate. Nutrition from food, what a concept! References [1] Zeisel S. Choline. In: Modern Nutrition in Health and Disease, 11th ed.
