What is in 5-MTHF (L-Methylfolate)?

- Its 5,000 mcg of L-methylfolate (filed by NIH under folate) is higher than 99% of the 7,022 folate products that print an amount; 71 list more.
The NIH database records one serving a day from the label's directions; its % Daily Values are for adults and children 4 or more years of age. The directions as printed are further down this page.
