Best Multivitamin for Women (2026)

Women’s nutritional needs differ significantly from men’s: higher iron requirements during reproductive years, critical need for methylfolate (especially preconception), higher calcium needs and specific support for hormonal balance. Here’s how top products compare.

Critical Nutrients for Women

Folate (as 5-MTHF, not folic acid): Essential for DNA synthesis and critical in early pregnancy. Folic acid requires enzymatic conversion that 40% of women complete inefficiently due to MTHFR variants. Methylfolate works directly regardless of genetics.

Iron: Menstruating women lose 1–2mg iron/day during periods. Target 18mg elemental iron in chelate form. Post-menopausal women and pregnant women have different needs — adjust accordingly.

Iodine: Thyroid hormone synthesis requires iodine. 150mcg/day for non-pregnant adults; 220mcg in pregnancy. Many women are borderline deficient, especially those avoiding dairy and iodized salt.
