Choline

How does Choline work?

Choline is similar to a B vitamin. It is used in many chemical reactions in the body. Choline seems to be an important in the nervous system. In asthma, choline might help decrease swelling and inflammation.

Are there safety concerns?

Choline seems to be safe for most adults when used appropriately.

High doses are more likely to cause side effects such as sweating, a fishy body odor, gastrointestinal distress, diarrhea, and vomiting.

There is some concern that increasing dietary choline intake might increase the risk of colorectal cancer. One study found that women eating a diet that contains a lot of choline have an increased the risk of colon cancer. However, more research is still needed to determine the effects of diet on colon cancer.

Dosing considerations for Choline.

The following doses have been studied in scientific research:

BY MOUTH:
  • For asthma: 500-1000 mg three times daily.
An average diet supplies 200-600 mg of choline daily. Adequate Intake (AI), as established by the Food and Nutrition Board of the National Institute of Medicine, for adults is 550 mg per day for men and breast feeding women; women, 425 mg per day; pregnant women, 450 mg per day. For children 1-3 years the AI is 200 mg per day; 4-8 years, 250 mg per day; 9-13 years, 375 mg per day; for infants less than 6 months, 125 mg per day; infants 7-12 months, 150 mg per day.

Daily Upper Intake Levels (UL, the highest level of intake that is not likely to cause harm) for choline are: 1 gram daily for children 1-8 years, 2 grams for children 9-13 years, 3 grams for children 14-18 years, and 3.5 grams for adults over 18 years of age.
