Choline
Other name(s)
choline bitartrate, choline chloride, choline dihydrogen
General description
Choline is a part of many chemicals within the body. It’s water-soluble. All of the
jobs of choline are not yet known. It may be needed for your liver and kidneys to
work well. Choline is also a part of the neurotransmitter acetylcholine. This is a
chemical that passes messages between nerves. It also passes messages between nerves
and muscles.
Choline is also the building block of lecithin and sphingomyelins. Lecithin is a part
of cell walls, plasma, and lipoproteins. Sphingomyelin is the insulating material
of brain and nerve tissue.
Medical uses
You can get all the choline you need from your diet. Choline deficiency happens only
in rare cases. For this reason, the use of choline supplements is limited. Choline
doesn’t have an established use as a supplement in healthy people.
Unproven claims
There may be benefits that have not yet been proven through research.
Choline supplements may help treat neurological issues due to the cholinergic system.
But studies show that these supplements don’t affect brain metabolism.
Choline is claimed to help treat these conditions:
Choline supplements are said to reduce cholesterol, control mood swings, and protect
the liver from damage due to alcohol. They also may lower blood pressure, boost memory,
and treat Alzheimer disease. Choline may also enhance athletic performance.
Choline may help prevent neural tube defects in pregnancy. It also aids in fetal brain
development.
Recommended intake
The Adequate Intake (AI) is the level needed to ensure nutritional adequacy. Most
people in the U.S. don't get enough choline in their diet.

About 9 in 10 to 19 in 20 pregnant people don't meet the AI for choline. Prenatal
vitamins usually contain little or no choline. Some studies suggest that low choline
levels in pregnancy are linked with an increased risk for neural tube defects. But
other research found no such link.
Foods that contain choline include meat, poultry, fish, dairy products, egg yolks,
soybean, wheat germ, peanuts, broccoli, cauliflower, and liver.

Choline deficiency in animals may lead to liver problems and kidney damage. These
liver problems have led to liver cancer in laboratory animals. But this has not yet
been found in humans.
People being fed by IV may have low serum levels of choline, which may require them
to need choline supplements
Side effects, toxicity, and interactions
Choline may cause a stomachache, diarrhea, or loose stools. This can happen at normal
doses. Large amounts (about 20 g) of choline may cause other side effects. These can
include dizziness, low blood pressure (hypotension), and fishy body odor. They can
also include depression and heart rhythm problems.
Choline may cause depression in some people. You should not use choline if you have
bipolar disorder.
People who are pregnant or breastfeeding should talk to their healthcare providers
before taking any supplements.
There are no known interactions between choline and any food or medicine. People with
low folate levels may need more choline.
