Why this scored 68/100
Optimum Nutrition Gold Standard 100% Whey is the reference sports-nutrition whey blend — 24g protein per serving from whey isolate + whey concentrate + whey peptides, 5g+ BCAAs, informed-choice-tested for banned substances at various points, and Glanbia-owned (large ingredient supplier). The evidence base for whey protein on muscle-protein synthesis is the most-studied in sports nutrition (Devries 2015, Morton 2018 meta-analysis, Jager 2017 ISSN position stand). Glanbia's whey supply is documented cGMP, and Gold Standard has held Informed-Choice certification on many production runs (batch-dependent). Held out of Verified by: (1) the blend obscures the ratio of isolate to concentrate to peptides ('blend' formulation ambiguity), (2) sucralose and artificial flavor system in most flavors, and (3) per-lot heavy-metal COAs are not publicly posted. Category-standard for whey and a defensible pick for the strength-training user.
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.
