Muscle Faktor's adult gummy multivitamin containing vitamins A, C, D, B6, B12, biotin, folate, plus zinc and iodine. Gummy multivitamins have real trade-offs: (1) they carry added sugar or sugar alcohols (matters for macros, dental health, and blood glucose), (2) they impose a low mass ceiling on each nutrient (hard to fit therapeutic amounts of calcium, magnesium, or vitamin C into a chewable gummy), and (3) evidence base for multivitamins in general population is mixed (USPSTF 2022 insufficient for CVD/cancer prevention; COSMOS-Mind modest cognitive benefit in older adults). Muscle Faktor's gummy is a straightforward take on the category. Description begins to itemise ingredients (sodium citrate, retinol acetate, ascorbic acid), which is a positive signal. 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.
