Folic acid is the synthetic form of folate, which is a water-soluble vitamin B9. It is the crucial ingredient in the synthesis and repair of DNA (Deoxyribonucleic acid) and RNA (Ribonucleic acid). Folate is the naturally available form of vitamin B9, while folic acid is the man-made form. Folate is naturally seen in green leafy vegetables, fruits (banana, watermelon, oranges), okra, asparagus, mushrooms, meat (liver and kidney), dried beans, peas, and nuts. Because of its health benefits, folic acid is added in bread, cereals, cookies, and other grain products.
Folic acid must be converted into active vitamin B9, known as 5-MTHF (L-Methylfolate) before the body can use it. This is a four-step process that requires several enzymes, including an enzyme called MTHFR (Methylenetetrahydrofolate reductase). Some people have a genetic mutation that makes enzyme MTHFR less effective, leading to a folic acid build-up in the blood. This has been linked to negative health impact in some people. It might cause poor immunity, reduce brain function, and increases the growth of pre-existing cancer.
