        Frequently Asked Questions

        What is L-Methylfolate and how is it different from folic acid?

        L-Methylfolate is the active form of folate that your body can use immediately. Folic acid needs to be converted—and some people can’t do that well because of genetic mutations like MTHFR.

        What is Methyl B12 and why is it paired with L-Methylfolate?

        Methyl B12 (aka Methylcobalamin) is a highly bioavailable form of B12 that works synergistically with L-Methylfolate to support brain health, energy, and mood.

        Is this product safe if I’m pregnant or breastfeeding?

        Check with your doctor first. L-Methylfolate is often recommended during pregnancy, but always confirm with your healthcare provider.

        Can this supplement interact with medications?

        It is possible L-Methylfolate may interact with certain medications. It is always best to check with a healthcare provider before starting any supplements.

        Are there any known side effects?

        Most people tolerate it well. If you feel like you are sensitive to higher doses, you can work your way up to the full dose over time.


        How do I take it — with food or without?

        It can be taken with or without food, but some people prefer it with a meal to avoid mild stomach discomfort.
