Why this scored 60/100
Zinc is a genuinely essential trace mineral (RDA 11 mg/day men, 8 mg/day women) with clear evidence for immune function, wound healing, taste and smell, reproductive function, and skin health. Deficiency is real and documented in vegetarians, elderly, alcohol-use-disorder patients, and users with GI absorption issues. Zinc lozenges started at cold symptom onset have Cochrane-review support for shortening cold duration (~30% reduction in some analyses). The description accurately identifies zinc's roles in immunity, skin, and hair health. Safety needs attention: chronic supplementation above 40 mg/day (tolerable upper intake) depletes copper via shared intestinal transporters and can cause anaemia and neurologic symptoms over months. Liquid concentrates typically deliver zinc as sulphate, gluconate, or picolinate; form is not disclosed. Solid Standard on a legitimate essential mineral, held back by lack of form and dose 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.
How to read the Evidence dimension
80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
0–19: No credible evidence base or unverifiable claims.

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.
