Why this scored 63/100
Potassium citrate is an FDA-approved prescription drug (Urocit-K) for renal tubular acidosis and calcium-oxalate kidney stone prevention, and an over-the-counter supplement for general potassium repletion. Dietary potassium intake in the US averages 2,400-2,800 mg/day against an Adequate Intake of 3,400 mg (men) / 2,600 mg (women), so mild insufficiency is genuinely common. Evidence for supplemental potassium citrate is strongest for reducing recurrent calcium-oxalate stones (Ettinger 1997, Barcelo 1993) and for modest blood pressure reductions in salt-sensitive hypertension. The citrate anion alkalinizes urine and may reduce bone resorption, though the bone-density claim is not fully settled. The FDA restricts OTC potassium supplements to 99 mg per tablet as a safety measure — dietary insufficiency at this dose requires many capsules per day to close the gap. Bulkessentials should disclose exact mg elemental potassium per capsule, citrate salt vs other forms, and per-lot COAs. Scored Standard: a legitimate, well-characterized mineral supplement with specific evidence-based use cases.

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.
