Methylenetetrahydrofolate Reductase (MTHFR)

Methylenetetrahydrofolate reductase (MTHFR) is an important enzyme in the body that helps process B vitamins, especially folate, to support healthy DNA production and repair. It converts a form of folate into a usable form necessary for making methyl groups, which are vital for many bodily functions, including supporting brain health and regulating homocysteine levels in the blood. Variations or mutations in the MTHFR gene can affect how well this enzyme works, potentially influencing risks for certain health issues like cardiovascular disease or reproductive problems.
