5-MTHF is the best form of folic acid and may be taken during pregnancy (please, never take a synthetic form). It plays an essential role in methylation, it enables the conversion of homocysteine to methionine, the production of serotonin and melatonin, and it is indirectly involved in the synthesis of DNA. It also helps with depression, megaloblastic anemia, and renal and hepatic impairment. It is a must-have for everybody who takes MB12 especially big doses. Good solid brand. Stay healthy!

Advanced form of folate, not cheap folic acid.

This is an advanced form of folate, not the cheap, conventional folic acid that can do more harm than good. Works well to raise blood levels of folic acid. Best taken together with a good B complex or a good multivitamin that contains the rest of the B vitamins in bioavailable forms.

Me and my husband started taking this product. I saw this in Youtube, recommended by a doctor so we decided to choose this brand. Ingredients look good especially it’s Active Folate. About the quality, can’t tell yet because we just started to take but I’m excited about the result! Well packaged.

good methylfolate

The quality is excellent, the size of the capsule is ok, not big. Methylfolate of the new generation, which gives energy and does not stimulate the appetite

Great product

I have a MTHFR variant homozygote which makes me very poor at methylation and this helps me. I take this every second day and use Folinic acid (1 drop) the other day
