A daily multivitamin with added 'immunity boost' framing centred on vitamin C and zinc. Multivitamin category evidence remains mixed (USPSTF 2022 insufficient for CVD/cancer prevention, COSMOS-Mind modest cognitive benefit in older adults). Immune-boost framing is technically true for correction of specific deficiencies — zinc deficiency impairs innate immunity, vitamin C deficiency (scurvy) is an immune catastrophe — but 'boost' implies above-baseline enhancement that supplementation in a well-nourished person does not reliably produce. Real supported immune claims: zinc lozenges may shorten cold duration when started at symptom onset; vitamin C daily may shorten cold duration slightly (Cochrane 8-14%). Solid low-Standard on the mixed evidence base and missing per-ingredient milligram disclosure.
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

The Vyvata score measures product integrity against a published rubric, not customer sentiment. Vyvata does not aggregate, republish, or license third-party reviews — the links below open search pages on their respective platforms.
Every VSF-related metafield surfaced verbatim. Nothing hidden. If you spot data that looks wrong, let us know.
Every score is set from the published rubric, audit-logged, and rescored whenever new evidence emerges (published trials, updated labels, third-party testing releases). Every vendor is scored on the same criteria — no pay-to-play. See our editorial-independence disclosure for the full policy, including brands with an editorial relationship to this site.
