                                Research suggests that up to half of the population may have a common genetic variation in the MTHFR gene, which affects the body's ability to process certain B vitamins. Understanding what vitamins to avoid with MTHFR is crucial for those with this mutation, as synthetic folic acid can accumulate and potentially cause issues.
