Why this scored 72/100
Optimum Nutrition Gold Standard Whey Isolate — mainstream sports-nutrition reference-quality whey protein. Whey isolate has extensive RCT support for muscle protein synthesis (Jäger 2017 ISSN position stand). Optimum Nutrition has real manufacturing scale + reasonable quality track record. Whey isolate is higher-purity than concentrate (>90% protein vs ~80%). Held below Elite by (1) not NSF Certified for Sport visible on this SKU (though Gold Standard 100% Whey concentrate line is Informed Choice certified); (2) high-price point + significant use of artificial flavorings/colors depending on flavor; (3) sustainability profile thin. Would move to Elite 85+ with NSF sport cert + cleaner flavoring.

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.
