Folate is an essential B vitamin (B9) needed for producing red and white blood cells in bone marrow and transforming carbohydrates into energy. Folate is especially important during periods of rapid growth, such as pregnancy, infancy, and adolescence.

It’s best to get folate from whole foods. Folic acid, often confused with folate, is a synthetic form of vitamin B9 used in supplements and added to processed food products, such as flour and breakfast cereals. Several studies indicate that chronically elevated levels of unmetabolized folic acid may have adverse health effects. High levels of unmetabolized folic acid have been associated with increased cancer risk. Among elderly people, high folic acid levels can mask vitamin B12 deficiency which, if untreated, may increase the risk of dementia and impaired nerve function.
