Question: I was told I have a MTHFR gene mutation. What do I need to know about taking B vitamins?
Answer: The MTHFR gene mutation may make your body less efficient at converting folic acid and folate into L-methylfolate, the active form of folate in the body. People with this mutation may also be more likely to be deficient in vitamin B-12. Although certain forms of B vitamins are sometimes promoted for people with this mutation, they may not be necessary. For more about this, see the "What to Consider When Using" section of the B Vitamin Supplements Review >>
