Folate supplements

Half of the 7,022 folate supplements in the NIH label database that print an amount list 400 mcg or less per serving; the middle half list 200 mcg to 400 mcg (DSLD version 9.4.0, January 2026). The 123 products whose only supplement ingredient is folate list a median of 800 mcg.

How much folate do supplements contain?

The median product lists 400 mcg per serving. One in ten lists 100 mcg or less, one in ten 800 mcg or more. The amount printed most often is 400 mcg (2,828 products).

Which forms of folate do labels name?

Methylfolate (5-MTHF) is the form named most often: 2,069 of the 12,112 folate products (17%), ahead of folic acid (2,018, 17%) and folinic acid (159, 1%). A product naming two forms counts in both; the table below gives every form.

• Methylfolate (5-MTHF)
• Folic acid
• Folinic acid

Which products list the most folate?

On-market products, per serving, with a plausible amount: the rule leaves out likely entry slips, such as an amount far beyond every other label with no %DV or strength on the label to back it (each product page still shows its own amount, marked).
