Metabolically Active Folate Superior Bioavailability Quatrefolic® A Dietary Supplement Vegetarian/Vegan Non-GMO How It Works: Folate consumed in the diet or from supplements must be converted to its active form, 5-Methyltetrahydrofolate (5-MTHF), to be used by the body. This is a multi-step biochemical process that, in some circumstances, may not be efficient enough to meet the body's needs. In addition, unlike folic acid, 5-MTHF can penetrate the blood-brain barrier. This product utilizes a patented form of 5-MTHF with superior bioavailability.

Hope it's good
First timer with this, not much noticeable difference though/yet. Tablet is easy enough to swallow & is tasteless.

Excellent
It't excellent methylfolate. Ingredients is good, minimal bed ingredients. It's better for use methylfolate than folic acid.

The Best Folate
Fantastic fall light supplement product to help confidently manage MTHFR gene mutation. Made all the difference when I started taking it, with noticeable and immediate benefit. Cannot recommend more.

Very good
This is a very good product! I appreciate that it provides the benefits of folate without the niacin flush. It gives me a great sense of energy and the package is convenient. A positive effect overall. It doesnt taste anything, i suffer for the mtfhr gene mutation so the folic acid quality helps with this issue to me

Lovebit
Easy to swallow. I have MS and I don’t really feel it, but I know this helps together with the other things I take. I love iHerb, you can find everything you need there.

I don’t usually write reviews, but this one deserves it. I could actually feel the difference — more energy, less fatigue, and overall I just felt stronger. This has been the best result I’ve had so far.

Great
I’ve been taking this 5-Methyl Folate and it works really well for me. I like that it’s a bioavailable form of folate and not synthetic folic acid. It helps me feel more balanced and supports my mood and energy. Easy to take, gentle on the stomach, and I appreciate that it’s vegan and non-GMO. Great quality supplement!
