Why this scored 58/100
Metabolic Nutrition Hydra EAA claims 18 g of essential amino acids plus hydration electrolytes per serving. If the 18 g label figure is delivered as verified essential amino acids (not a mixed EAA plus BCAA plus non-essential blend), that is a high dose for the category — 15-20 g EAAs approaches the muscle protein synthesis response of a full whey scoop. Transparency concerns hold the score to Standard: the 18 g figure needs verification against the full amino-acid breakdown (specifically the leucine content, which must clear roughly 2.5-3 g to hit the muscle protein synthesis trigger), and Metabolic Nutrition does not publish per-lot COAs at NutraBio's level. Electrolyte doses in amino products are typically token amounts, not real hot-weather replacement. Safety at label servings is fine. A defensible Standard pick for someone who wants a large EAA scoop; the muscle protein synthesis effect ceiling is capped by the leucine content, which the marketing does not always fully specify.

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.
