Why this scored 42/100
A 'potassium concentrate' whose product description erroneously describes calcium — a copy-paste labelling error where the description text discusses calcium's role in bones and muscles rather than potassium. That labelling error alone would justify a Rejected tier under misleading_naming/misleading_labelling. Setting that aside, potassium is an essential mineral (adequate intake 3400 mg/day for men, 2600 for women) and most Americans consume below AI. Real deficiency is documented and can be corrected. However, supplemental potassium in dose forms above 99 mg per pill is FDA-restricted for a specific safety reason: high-dose potassium can cause life-threatening hyperkalaemia in users with kidney disease, on ACE inhibitors/ARBs, or on potassium-sparing diuretics, and undisclosed-dose liquid potassium supplements bypass that safety architecture. Rejected on both labelling error and safety-window narrowness.

Evidence & sources
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.
