Zinc + vitamin C + vitamin D gummies — Martineau 2017 supports vitamin D for respiratory infection prevention in deficient populations, and zinc/C have cold-duration evidence (Hemila 2011). Gummy delivery typically compromises on elemental zinc (5-15mg) and D3 dose (400-1000 IU), plus added sugar. Standard tier — good adherence delivery, sub-therapeutic for correction of deficiency. Would upgrade with 2000+ IU D3, 25mg+ zinc, reduced sugar.
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.

Strongest: Evidence at 62/100 (quality of published RCT support for the active ingredients at the label dose) and Safety at 62/100 (adverse-event profile, interaction risk, and dose ceiling). Weakest: Formulation at 55/100 (dose adequacy, bioavailability form, and ingredient redundancy) and Sustainability at 50/100 (sourcing practices, packaging, and corporate practice). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.
No third-party certifications (NSF, USP, ConsumerLab, or equivalent) were on record at the time of scoring. This affects the Manufacturing dimension score. The manufacturer may test internally or have obtained certification more recently — check the current product label for the most up-to-date information.
