Start here: A multivitamin cannot replace a varied diet, and there is no single standard formula. Your age, sex, diet, pregnancy status, health conditions, and medications can change what is appropriate.
Read the serving size first
The amounts in the Supplement Facts panel apply to the listed serving, which may be one tablet, several capsules, or another measured amount. Compare products by the full daily serving rather than by one pill.
Compare the % Daily Value
The % Daily Value helps you compare how much of each nutrient a serving provides. More is not automatically better. Check other supplements and fortified foods you use so the combined amount does not push nutrients above safe upper limits.
Look beyond the front label
| Check | Why it matters |
|---|---|
| Supplement Facts | Shows serving size, dietary ingredients, and amounts per serving. |
| Other ingredients | Lists fillers, colors, flavors, and sweeteners. |
| Directions and warnings | Explains suggested use and product-specific cautions. |
| Manufacturer details | Gives you a contact for questions about the product. |
Be careful with specialized formulas
Products marketed for energy, immunity, performance, or weight control may contain herbs and other ingredients in addition to vitamins and minerals. Review every ingredient rather than assuming a “natural” label means it is appropriate for you.
Ask before you add
Talk with a doctor, pharmacist, or registered dietitian if you are pregnant, planning pregnancy, over age 50, following a restrictive diet, taking medication, managing a condition, or considering high-dose nutrients.
Dietary supplements are not approved by the FDA for safety and effectiveness before they are sold. Verify the exact label and avoid products that promise to diagnose, treat, cure, or prevent disease.
