Listing snapshot
Why it is on the shortlist
Four Folate lanes separate modest, form, mid, and caution doses where applicable. Map: Folate. Related lane: NOW Folic Acid 800 mcg.
Boundaries
Methylfolate is a form note, not a genetic clinic. Count DFE vs mcg on the live label. Pregnancy questions stay clinical. Do not stack all four lanes.
