> You may have heard that if you have an MTHFR variant, you should avoid folic acid and should take other types of folate, such as 5-MTHF. However, this is not true. People with an MTHFR gene variant can process all types of folate, including folic acid. Folic acid is the only type of folate shown to help prevent neural tube defects (NTDs).
Unless you’re very sure you’re not MTHFR mutated.
