Why this scored 72/100

NutraBio CGT-Max combines three well-established sports-nutrition ingredients — creatine monohydrate, L-glutamine, and taurine — in a single powder. Creatine at 3-5 g is the highest-evidence sports supplement in the entire category; taurine at 1-2 g has RCT support for exercise-endurance and cardiovascular effects; L-glutamine has been over-marketed relative to its RCT support (immune-modulation and gut-integrity effects at higher doses in specific catabolic states, minimal muscle-building effect in normal-diet athletes). NutraBio publishes full quantitative doses, third-party tests every lot, and does not proprietary-blend the actives. The formulation delivers the creatine and taurine cleanly and adds glutamine at whatever dose the label specifies — the honest read is that the creatine is the main worker and the other two are complementary rather than additive game-changers. Solid Verified-tier product for someone wanting a bundled cell-volumizing formula rather than separate scoops; single-ingredient creatine plus optional standalone taurine is equally effective and often cheaper.

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.
