Choline information

The metabolism of choline is closely interrelated to that of methionine, and methyl-folate, yet choline is at times treated by some nutritional specialist as a stepchild in nutrition.

Choline is an interesting nutritional ingredient and it has been suggested that it be of use in the treatment of vitamin d toxicity. It is mainly found in the body in phospholipids, such as lecithin (phosphatidylcholine).

Required for

Choline assists in controlling your weight as well as cholesterol levels, keeping cell membranes healthy and in preventing gallstones. It is also most useful in the maintenance of the nervous system, assisting memory, and learning and may help to fight infections, including hepatitis and AIDS. Choline is critical for normal membrane structure and function.

Choline is the major precursor of betaine, and it is used by the kidneys to maintain water balance and by the liver as a source of methyl-groups for methionine formation. It is also used to produce the important neurotransmitter acetylcholine.

It assists in nerve impulse transmission, gallbladder regulation, liver functions and lecithin production.

Deficiency indications

A deficiency of choline does not happen easily but if it is deficient it may lead to liver disease, raised cholesterol levels, high blood pressure as well as kidney problems, Choline deficiency may also manifest itself the inability to digest fats, stunted growth and fatty buildup in the liver.

Memory and brain function could also be impaired.

Dosage

The dosage underneath is the Recommended Dietary Allowance (RDA), but be aware that this dosage is the minimum that you require per day, to ward off serious deficiency of this particular nutrient. In the therapeutic use of this nutrient, the dosage is usually increased considerably, but the toxicity level must be kept in mind.

The dosage is relative to the amount of fats ingested in the diet, but for a guide you can use male 550 mg/ per day and female 425 mg/day per day, although mega dose vitamin proponents use far higher dosage.

Toxicity and symptoms of high intake

The maximum level of choline has been set for safety at 3.5 g/day.

Taking too much choline could result in your body smelling fishy, may cause nausea, depression, and could trigger existing epilepsy. Hypotension, sweating, salivation and diarrhea have also been reported.

Best used with

Should be taken in the same dose as inositol and together with the B group vitamins as well as vitamin A and linoleic acid.

When more may be required

Should you consume alcohol, refined sugar or taking large amount of nicotinic acid you might need extra choline.

Enemy of nutrient

Choline is lost in food processing, storage and cooking.

Other interesting points

Choline, together with fat, inositol and essential unsaturated fatty acids make up lecithin, and needs a co-enzyme containing vitamin b6, and magnesium to be produced.

If lecithin is in short supply is may allow your blood cholesterol levels to become elevated.

Food sources

Choline is found in egg yolks, beef, wheat germ, oats, nuts
