The 2 oz concentrate format of iodine. Same evidence base as the mineral-water version — iodine is essential (RDA 150 mcg adults; 220 pregnancy; 290 lactation), and deficiency remains a real public-health concern despite iodised salt programs. The 2 oz concentrate format is intended for dilution before consumption, which requires user attention to dose since it's easier to over-consume from a concentrated liquid than from a diluted mineral water. Description accurately identifies iodine's role in thyroid hormones. Same safety concerns as the mineral water: narrow safety window (tolerable upper intake 1100 mcg/day), thyroid conditions require endocrinologist review before supplementation, and form is not disclosed. 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.
