Supplements
The right women's multivitamin depends almost entirely on life stage. Premenopausal women with periods usually benefit from the iron and 400 mcg of folate in a standard women's formula; after menopause, routine iron is unnecessary and worth avoiding. Third-party testing matters more than label maximalism. Our top pick is the Nature Made Multivitamin for Her.
How We Picked
We selected formulas on three criteria: an iron content that matches the intended user (18 mg for premenopausal, little or none after menopause), at least 400 mcg of folate for women who could become pregnant, and verified third-party testing such as USP. We downgraded products that bury minerals in proprietary blends without stated amounts.
A. Nature Made Multivitamin for Her — Best Overall
Nature Made Multivitamin for Her
Nature Made
- USP verified for potency and purity
- Includes 18 mg iron for menstruating women
- 400 mcg folate
- Once-daily tablet
- Low cost per serving
Why we picked it: USP verification is the strongest quality signal available in this category, and very few mainstream multivitamins carry it. The iron and folate levels match what premenopausal women actually need, and the price is low enough to sustain indefinitely.
B. One A Day Multivitamin for Women — Best Value
One A Day Multivitamin for Women
One A Day
- Complete standard vitamin and mineral panel
- Formulated with iron and folic acid
- Includes calcium and vitamin D
- Once-daily tablet
- Widely stocked and inexpensive
Why we picked it: The formula leans on the nutrients women's intake surveys most often flag — iron, folate, calcium and vitamin D — without inflating anything to headline-grabbing percentages. It is the practical default.
C. OLLY Women's Multivitamin Gummies — Best If You Hate Pills
OLLY Women's Multivitamin Gummies
OLLY
- Chewable gummy format
- Includes biotin, folate and vitamin D
- No iron, suitable post-menopause
- Pleasant flavour improves adherence
- NSF-certified manufacturing
Why we picked it: Gummies cannot carry as much mineral content as a tablet — they are physically too small — but a supplement you take beats one you avoid. The absence of iron also makes this a sensible fit after menopause.
Iron: The Decision That Actually Matters
This is where women's multivitamins earn their name. Menstruating women need roughly 18 mg of iron per day against 8 mg for men, and iron deficiency remains one of the most common nutrient deficiencies worldwide, often showing up as fatigue and poor exercise tolerance well before anaemia appears on a blood test. After menopause, requirement drops back to 8 mg and routine supplementation stops being helpful, because excess iron accumulates rather than being excreted. If you are postmenopausal, choose an iron-free formula unless a blood test says otherwise. Our iron supplements for women guide covers testing and dosing.
Folate and Why 400 mcg Is the Number
Folic acid at 400 mcg daily before conception and in early pregnancy substantially reduces the risk of neural tube defects — one of the most robust findings in nutrition, confirmed across Cochrane reviews. Because roughly half of pregnancies are unplanned and the neural tube closes before most people know they are pregnant, public health guidance recommends 400 mcg daily for all women who could become pregnant, not just those trying. Standard women's multivitamins supply exactly this. Prenatal formulas go higher and add DHA and more iron; if you are actively trying to conceive, use a prenatal vitamin instead.
Calcium, Vitamin D and Bone Loss
Bone density falls fastest in the years immediately around menopause as oestrogen declines, which is why calcium and vitamin D appear in nearly every women's formula. The catch: a multivitamin can only fit a fraction of the 1,000–1,200 mg daily calcium target — usually 200–300 mg — because calcium carbonate is bulky. Treat the multivitamin as a top-up on dietary calcium, not a replacement, and check that vitamin D is present at a useful amount. See supplements for osteoporosis for the fuller picture.
What the Evidence Says About Benefit
The Women's Health Initiative followed more than 160,000 postmenopausal women and found no association between multivitamin use and cancer, cardiovascular disease or total mortality. That is the appropriate baseline expectation: a multivitamin corrects gaps, it does not extend life in a well-fed population. Where it clearly helps is in people with genuine shortfalls — restrictive diets, malabsorption, heavy periods, pregnancy, or older age when B12 absorption declines.
Gummies Versus Tablets
Gummies solve adherence and lose potency. A gummy has limited room for minerals, so most contain no iron, little or no calcium, and less magnesium than the tablet version of the same brand. They also contain added sugar or sugar alcohols. If you take a multivitamin reliably in tablet form, stay with tablets. If you have abandoned three bottles of tablets, a gummy you finish is objectively better than a tablet you do not.
Matching the Formula to Your Stage
A short version. Teens and twenties: standard women's formula with iron and folate. Trying to conceive or pregnant: prenatal, not a general multivitamin. Perimenopause: keep iron if periods are still heavy, prioritise vitamin D and magnesium — see vitamins for perimenopause. Postmenopause: iron-free, with attention to calcium, vitamin D, B12 and protein intake.
Frequently Asked Questions
Does a women's multivitamin need to contain iron?
It depends on life stage. Menstruating women need about 18 mg of iron daily and often benefit from the amount in a standard women's formula. After menopause the requirement drops to 8 mg and routine supplementation is generally not recommended, because excess iron accumulates rather than being excreted.
How much folate should be in a women's multivitamin?
At least 400 mcg daily for any woman who could become pregnant. This level is well established to reduce the risk of neural tube defects, and because the neural tube closes very early in pregnancy, guidance applies to all women of reproductive age rather than only those actively trying to conceive.
Are gummy multivitamins as good as tablets?
They are less complete. A gummy cannot physically hold much mineral content, so most contain no iron, little calcium and less magnesium than the equivalent tablet, and they add sugar. They are a reasonable choice only if the format is what makes you take it consistently.
Can a multivitamin replace calcium supplements?
No. Most women's multivitamins supply only 200–300 mg of calcium against a 1,000–1,200 mg daily target, because calcium is too bulky to fit in a single tablet. Treat the multivitamin as a top-up alongside dietary sources such as dairy, fortified alternatives, tofu and leafy greens.
