Best Multivitamin for Women UK 2026 — What to Look For

Why Women Have Specific Nutritional Needs

Women’s nutritional requirements differ from men’s at every life stage. Menstruating women need more iron (the UK recommendation is 14.8mg/day vs 8.7mg for men). Women of childbearing age need adequate folate (400mcg/day) for foetal development. And the majority of UK adults — across all genders — are deficient in vitamin D, with women particularly affected due to lower outdoor activity in older age groups.

Key Nutrients to Check For

Iron

Especially important for women aged 19–50. Look for ferrous bisglycinate (gentler on the stomach than ferrous sulfate) or ferrous fumarate. Avoid multivitamins with iron if you’re post-menopausal — excess iron is associated with increased cardiovascular risk in older women.

Folate / Folic Acid

Essential for women who could become pregnant. The NHS recommends 400mcg daily from before conception to 12 weeks of pregnancy. Look for methylfolate (the active form) if you have the MTHFR gene variant, which reduces folic acid conversion.

Vitamin D3

The NHS recommends all UK adults take 10mcg (400 IU) of vitamin D daily, particularly between October and March. Most multivitamins underdose this — check it’s at least 10–25mcg (400–1000 IU).

What to Avoid

Megadose A/E vitamins (fat-soluble, accumulate toxically), excessive iodine in thyroid-sensitive women, and proprietary blends that hide individual dosing.
