This guide explains folate terminology, 5-MTHF, folic acid, and label reading.
Folic acid
Folic acid is a synthetic form of folate used in fortified foods and supplements. Public-health guidance around folic acid is especially important for people who can become pregnant.
5-MTHF
5-MTHF is a reduced folate form used in supplements. It can also appear as methylfolate or L-5-MTHF.
How to read the label
Supplement Facts can list folate in dietary folate equivalents and identify the source form in parentheses. Compare total folate, form, serving size, and the rest of the formula.
What to check before you choose a product
Read the serving size, ingredient list, amount per serving when provided, directions, warnings, and storage information. Keep ingredient research separate from claims about a finished multi-ingredient product.
