Why this scored 62/100
RAW Nutrition CBUM Whey Blend is a Chris Bumstead-signature microfiltered whey blend at 25 g protein per scoop with low fat and low carbs. The base ingredient — microfiltered whey blend — is a legitimate protein source at the standard 25 g dose that cleanly hits the muscle-protein-synthesis threshold. The 'micro-filtered whey protein blend' description suggests a mix of whey concentrate and whey isolate rather than pure isolate; that is a normal formulation choice that reduces cost while retaining most of the muscle-building effect. Transparency concerns hold the score at Standard: 'blend' without specifying the isolate/concentrate ratio, the specific processing details, and per-lot COA publication is not at NutraBio-level. Chris Bumstead's signature branding adds a marketing premium without adding demonstrable formulation quality. The base product is fine for post-workout use; better-documented isolates at similar prices exist. Standard-tier signature-athlete whey.

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.
