A men's liquid multivitamin featuring magnesium, D3, K2, and a full B-vitamin spectrum. The category itself — daily multivitamins — has famously mixed evidence: the 2022 USPSTF review found insufficient evidence to recommend multivitamins for prevention of cardiovascular disease or cancer in healthy adults, while the recent COSMOS-Mind trial showed a modest cognitive benefit in older adults from a daily MVI. So the product category is defensible for niche use cases (dietary gaps, older adults, restricted diets) but not as a universal 'must-take.' The specific formulation choices — D3+K2 pairing for calcium partitioning, magnesium for typical dietary shortfalls — are sensible. Milligram-per-serving amounts for each nutrient are not surfaced in the description, which under Zero-Assumption Rule caps transparency credit. Solid Standard.
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.
