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.

I have compound heterozygous MTHFR so this helps me tremendously. I noticed a difference within a week. Less anxious, calmer, and more aware.

The Best

I have had an incredibly sensitive stomach for over 20 years. I cleaned up my diet almost 3 years ago, but improvement has taken a long time and there were still many things that would upset it. Triquetra L-Methylfolate (15 mg) plus Methyl B-12 was the very first supplement I bought after a friend recommended it as a Gary Brecka favorite. I had no reactions from this supplement, and I systematically built my supplement stack over the next 2 months. Triquetra makes very high quality supplements and have a very good rating on the SuppCo App.
