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.
Frequently asked questions
Auto-generated from Vyvata's scoring data for this product. For general questions about the store (shipping, returns, wholesale), see the site FAQ.
What is NutraBio Intra Blast?
NutraBio Intra Blast is a product from Ultimate Sport Nutrition, categorized under Protein & amino acids in the Supplements vertical. It is scored on the Vyvata Scoring Framework — an independent 6-dimension rubric applied uniformly to every product Vyvata lists.
How does NutraBio Intra Blast score on the Vyvata rubric?
72/100 overall — Verified tier (70–84 band). Per-dimension breakdown: Transparency 82, Manufacturing 78, Formulation 75, Evidence 72, Safety 72, Sustainability 55. Scored as of 2026-08-24.
Why did NutraBio Intra Blast score in the Verified tier?
NutraBio Intra Blast is a fully-disclosed intra-workout EAA/BCAA/electrolyte formula. NutraBio is one of the most transparent sports-nutrition brands — 100% open-label formulation policy, in-house testing published per lot, and NSF/GMP-registered facility. EAAs at ~10g plus electrolytes and glutamine represent a legitimate intra-workout stack (Jackman 2017 for EAA anabolic response). Ultimate Sport Nutrition is just a reseller; the score reflects NutraBio. Would move to Elite with independent NSF Certified for Sport batches.
What are the strongest and weakest aspects of this product?
Strongest: Transparency at 82/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) and Manufacturing at 78/100 (third-party testing, GMP compliance, and facility audit status). Weakest: Safety at 72/100 (adverse-event profile, interaction risk, and dose ceiling) and Sustainability at 55/100 (sourcing practices, packaging, and corporate practice). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.
Is NutraBio Intra Blast third-party tested?
No third-party certifications (NSF, USP, ConsumerLab, or equivalent) were on record at the time of scoring. This affects the Manufacturing dimension score. The manufacturer may test internally or have obtained certification more recently — check the current product label for the most up-to-date information.
What would move NutraBio Intra Blast to a higher tier?
Would move to Elite with independent NSF Certified for Sport batches.
