Why this scored 63/100
Nutrex Research is a legitimate US sports-nutrition brand with distribution at mass retailers and gyms. This SKU delivers 8 g of essential amino acids per serving including 6 g of BCAAs, plus electrolytes for hydration. Doses are disclosed at the class level, which is the primary requirement — 8 g EAA is at or near the anabolic threshold identified in Wolfe 2017 leucine-signaling work (~3 g leucine, roughly consistent with 6 g BCAA if leucine share is ~40-50%). The hydration angle is straightforward electrolyte replacement. The class-level RCT evidence for EAAs supporting recovery and preserving lean mass during caloric deficit is reasonable (Wolfe 2017 review, Church 2020). Held back from Verified by absence of visible third-party sport certification (Informed Sport, NSF Sport), which is a meaningful signal for competitive athletes given the historical contamination risk in this category. Solid Standard entry.

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.
