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.
