There are other well written review here on this product and I concur that this product is a very economical way to get the methyl form of folate. As explained by others, some people have difficulty with the methylation process and hence do better by taking the methyl form of folate. I have found that when I take this it gives my mood a boost. I have added this in addition to my regular B-complex which contains 400 mcg of folic acid. This way I ensure I am getting enough as I may not be converting all of the folic acid to a useful form. It is safe to take up to 800 mcg of folate per day. Folate is also needed to absorb vitamin B-12.
