Multivitamin Research Summary
Multivitamin research shows limited benefit for healthy adults eating varied diets—targeted nutrients beat kitchen-sink pills for most athletes.
Multivitamin research summary: large trials in generally healthy adults show little benefit for longevity or heart disease prevention—a daily pill does not erase a low-produce, low-protein diet. Some groups with documented gaps—pregnancy, strict vegan B12, malabsorption—may still need targeted nutrients, not necessarily a kitchen-sink tablet.
Quality varies by brand and dose; more is not better. Use labs and diet patterns first.
Pregnancy, malabsorption, and strict vegan B12 are separate targeted cases.
Common questions
-
Are multivitamins a waste of money?
For many healthy eaters, food covers basics and broad pills add little. Targeted supplements for confirmed gaps—guided by clinicians—are different from generic multis.
