Folic Acid Supplements: Is Methylfolate Better? Folinic Acid?
Proponents of folic acid supplements often think that more is better, both in dose amount and duration of supplementation. In our practice, we have seen the negative side effects of indiscriminate folic acid supplementation. It is not a supplement that should be taken long-term without specific biochemical laboratory testing and evaluation due to the very negative side effects that could arise. It is not only important to know who would benefit from taking folic acid and how much is beneficial, but there is also a need to understand which form is best for each individual patient.
What many people (especially practitioners) fail to understand the duality of folic acid activity. In one area, it’s a donor of methyl, so for an undermethylator, they think folic acid or methylfolate is a great thing. In actuality, that’s not correct.
