Search for information about MTHFR online and you'll quickly encounter two very different messages. One group screams if you have an MTHFR variant, avoid folic acid and use methylfolate instead. The other group insists that people with MTHFR variants can process folic acid, so there is no reason to avoid it. Today, we'll explore the research and answer the question "Do you really need to avoid folic acid if you have MTHFR?"
