If you have an MTHFR variant, take a closer look at your multivitamin. MTHFR plays a role in folate metabolism, and certain variants can reduce enzyme activity. But having a variant doesn't mean your body can't process folic acid at all or that folic acid is inherently harmful. This is why I believe in knowing your genetics and biomarkers before blindly supplementing. Don't just take what's on the shelf. Know what's actually in your multivitamin and why you're taking it.
