Why this scored 75/100
[Rescored via evidence crawl] Previous score 0 → new 75. Evidence found: NutraBio Base Aminos: pharmaceutical-grade EAAs, full disclosure of individual amino acid amounts, no proprietary blends. | Jackman SR et al. Branched-Chain Amino Acid Ingestion Stimulates Muscle Myofibrillar Protein Synthesis following Resistance Exercise in Humans. Front Physiol. 2017;8:390. | Wolfe RR. Branched-chain amino acids and muscle protein synthesis in humans: myth or reality? J Int Soc Sports Nutr. 2017;14:30 (EAAs superior to BCAAs).. Rationale: NutraBio's full-transparency EAA formula (9 essential amino acids in ratios designed to support muscle protein synthesis). Wolfe 2017 established EAAs as superior to BCAAs alone. Verified tier for practitioner-grade transparency + evidence-based EAA delivery.

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.
