Claim Verification: "Multivitamins and most supplements provide meaningful health benefits for the general healthy population." — Disproved

Automated fact-verification of the claim: "Multivitamins and most supplements provide meaningful health benefits for the general healthy population." Verdict: DISPROVED Key Findings 4 independent authoritative sources confirm the claim is false (threshold for disproof: 3). The U.S. Preventive Services Task Force (USPSTF) recommends against using beta-carotene and vitamin E supplements (Grade D — recommend against), and finds insufficient evidence to recommend multivitamins (Grade I). A 2022 systematic evidence review of 84 studies concluded that "vitamin and mineral supplementation provides little to no benefit in preventing cancer, CVD, and death." The NIH Office of Dietary Supplements states that multivitamin/mineral supplements (MVMs) "do not appear to reliably reduce the risk of chronic diseases when people choose to take these products for up to a decade (or more)."
