RAW Nutrition CBUM Itholate is a 25 g whey protein isolate serving formulated by Chris Bumstead. The base product — micro-filtered whey isolate at 25 g/scoop with low fat and low carbs — is a straightforward proven protein source that cleanly hits the muscle protein synthesis threshold. Isolate specifically (as opposed to concentrate or blend) reduces lactose content to under 1%, making it comfortable for mild lactose intolerance and appropriate for post-workout use. The 'Thavage lifestyle' branding is athlete-signature marketing. RAW Nutrition's documentation is decent for the sports space but not at NutraBio-level per-lot COA publication. The 2 lb tub size is a reasonable consumer trial size. Standard-tier competent whey isolate; the athlete-signature premium is real, and better-documented isolates at similar price points exist.
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.

The Vyvata score measures product integrity against a published rubric, not customer sentiment. Vyvata does not aggregate, republish, or license third-party reviews — the links below open search pages on their respective platforms.
Every VSF-related metafield surfaced verbatim. Nothing hidden. If you spot data that looks wrong, let us know.
Every score is set from the published rubric, audit-logged, and rescored whenever new evidence emerges (published trials, updated labels, third-party testing releases). Every vendor is scored on the same criteria — no pay-to-play. See our editorial-independence disclosure for the full policy, including brands with an editorial relationship to this site.
