“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”. It was discovered in 1862, yet it was not recognized as a required nutrient for humans until 1998.
“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 sphingomyelin). 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” .
Regarding Choline, WebMD reports, “Athletes use it for bodybuilding and delaying fatigue in endurance sports” . Low levels of Choline have been found in endurance athletes and supplementation may decrease fatigue during exercise .
The official Recommended Daily Intake of Choline is as low as 125 mg per day for infants up to 6 months of age to as high as 550 mg per day for lactating women (the RDI for non-lactating women is 450 mg per day) . The RDI for adult males is 550 mg per day .
