Question: Does folic acid act differently in the body than natural folate? | Masterjohn Q&A Files #68

They don't really. Everything that is said bad about folic acid is sort of true to an extent but has been completely exaggerated in some circles. What happens is you have an enzyme called dihydrofolate reductase, or DHFR. Its purpose is not to metabolize synthetic folic acid obviously because that folic acid molecule doesn't exist in the food supply. Its normal purpose is that every time that you use folate to participate in processes outside of methylation, such as DNA synthesis, you wind up producing dihydrofolate as a byproduct. DHFR recycles that and turns it into tetrahydrofolate, or THF. Tetrahydrofolate is what has the methyl group added to make methylfolate.

The question is, does that synthetic folic acid, we call that unmetabolized folic acid, does that cause harm? There are scientific hypotheses that it might, and it might, but there's no conclusive evidence of that. That's one side of the argument against synthetic folic acid. The other side of the argument is now that you are giving the DHFR enzyme more work, that means that might be detracting from the work that it has in recycling dihydrofolate that came out of the DNA synthesis reactions to make tetrahydrofolate.

People think that they just cut out white flour and therefore they're better off. No. You cut out white flour, now you need to do more work to make sure that you are actually getting your nutrients from whole foods because if you were eating six pieces of white toast that you didn't have to worry about getting nutrients from whole foods and now you do.
