Why this scored 42/100
Metabolic Nutrition Hydra Max is a diuretic capsule product marketed for water-weight reduction ahead of physique/bodybuilding competition. Diuretic supplements in the physique-prep category typically combine dandelion extract, uva ursi, juniper berry, potassium chloride, and sometimes theobromine or synephrine as stimulant diuretics. Auto-fail concerns are two-fold: (1) diuretic marketing for cosmetic water-weight reduction crosses into unverified_medical_claim territory when framed as safe daily-use — herbal diuretics can produce genuine electrolyte disturbance, dehydration, and cardiac arrhythmia risk in already-lean, under-hydrated bodybuilders during peak week, with documented deaths in the competitive bodybuilding community from combination diuretic use; and (2) products in this category commonly use proprietary blends. The intended-use profile itself is medically ambiguous. Rejected tier.

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.
