Best Multivitamins, Scored on a Public Rubric
A good multivitamin is insurance, not magic. It fills in dietary gaps — especially for nutrients like D, B12, iron, and magnesium where dietary intake often falls short — without trying to be a cure-all. The good products use bioavailable forms of each vitamin (methylfolate instead of folic acid, MK-7 instead of synthetic K1, methylcobalamin instead of cyanocobalamin) and skip megadoses of fat-soluble vitamins. We scored six on the rubric.
At-a-glance

| Thorne — Basic Nutrients 2/Day | Best overall — clinical-grade formulation | 9.2/10 |
| Ritual — Essential For Women 18+ | Best for women — iron included, transparent label | 8.7/10 |
| Nature Made — Adult Multivitamin Tablets | Best mainstream USP-verified option | 7.8/10 |
| Athletic Greens — Athletic Greens AG1 Daily Foundational Nutrition | All-in-one greens + multivitamin powder | 6.5/10 |
| Garden of Life — Vitamin Code Men's Multivitamin | Best whole-food-blend multivitamin | 7/10 |
| Centrum — One Daily Men's/Women's Multi | Most accessible low-cost option | 6.3/10 |
How we scored
Every product below is scored on six metrics, 0-10 each, with the weighting described on how we review. The criteria specific to this category:
- Bioavailable vitamin forms — methylfolate (not folic acid), methylcobalamin (not cyanocobalamin), MK-7 K2, D3 (not D2).
- Sensible doses — not mega-doses of fat-soluble vitamins (A, D, E, K).
- No proprietary 'superfood' or 'greens' blends hiding low-dose fillers.
- Third-party testing evidence (USP, NSF).
- Form — capsules and tablets over gummies (which typically omit iron and can't hold fat-soluble vitamins well).
- Value per day, not per bottle.
What to know before buying
- Men generally don't need iron in a daily multivitamin (iron accumulates). Women who menstruate usually benefit from iron inclusion.
- Gummies almost always leave out iron and often overdose on sugar — they're a compromise for compliance, not a quality choice.
- If you have the MTHFR variant, methylated B vitamins (methylfolate + methylcobalamin) are functionally preferred over folic acid + cyanocobalamin.

Frequently asked questions
For people with no dietary gaps, daily multivitamin use shows small and inconsistent benefits in large prospective trials (e.g., Physicians' Health Study II). For people with known dietary gaps — limited sun exposure, plant-based diet, restricted-calorie dieting, pregnancy — they can meaningfully close measurable deficiencies. Think of them as insurance, not a performance enhancer.
