Why this scored 68/100
Mother Earth Labs Grass Fed Whey Isolate is a US-sourced grass-fed whey protein isolate. The grass-fed sourcing is a genuine sustainability and nutritional plus over commodity conventional whey — grass-fed dairy has a modestly better omega-3-to-omega-6 ratio and conjugated linoleic acid content in the milk fat, though the effect on protein-only isolate (which contains minimal fat) is negligible. The main sustainability delta is animal welfare and pasture-management, which is legitimate. The base protein (whey isolate at typical 25 g/serving) is well-supported by RCTs for post-workout muscle protein synthesis. Transparency is decent — grass-fed is specified — but per-lot COA documentation is not published at NutraBio's level, and the specific amino-acid profile per serving is not typically detailed. A defensible Standard-plus-tier pick for someone who values grass-fed sourcing and is willing to pay the premium; the strict RCT-level uplift for post-workout muscle building is minimal versus conventional isolate.

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.
