Why this scored 62/100
Longevity Rx Cellular Hydration is an electrolyte stick pack (wild berry) with an optimised sodium-to-potassium ratio plus watermelon, celery, and coconut water for natural electrolyte content. The category — modern electrolyte powders (LMNT, Liquid IV, Nuun) — has real physiologic justification for endurance athletes, hot climates, hangovers, low-carb dieters, and post-illness rehydration. Sodium 500-1500 mg + potassium 200-400 mg is the standard therapeutic range. The 'drives hydration deep into your cells' framing is marketing — cellular hydration is a function of osmolality gradient, and while sodium/potassium do drive intracellular water shifts, the effect is not category-specific to this brand. Real electrolyte formulation, honest wellness category, held back from Verified by lack of per-serving mineral disclosure at the description level.

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.
