Choline is an essential nutrient that is found in dairy, meat, and nuts. It has been used to improve brain and lung function. Choline is also often recommended to pregnant women to improve fetal health. It can be taken as a pill or powder. It can also be injected into the bloodstream by a healthcare provider.
100 to 650 milligrams once daily.
What Research Shows
- Cancer —likely to lower the risk of cancer when used with betaine C1
May Be Effective
Not Enough Data to Assess
Editorial process and description of evidence categories can be found at EBSCO NAT Editorial Process.
It is likely safe to take choline in small doses for a short time. Women who are pregnant or breastfeeding should not take excessive amounts of choline. Not enough studies have been done to say whether it is safe to use for a long period. H1
