Evergreen monthly benchmark — May 5
Protein Powder
May 5Rank Trend
How top brands moved week over week. Rank 1 is the top position.
The protein powder category remains an Optimum Nutrition/Dymatize duopoly at the top of AI recommendations. Nutricost has consolidated as Claude's value pick across all 3 prompt types, a meaningful brand momentum signal. Transparent Labs holds steady in 3 of 4 models as the premium pick. ChatGPT continues to over-index on commerce-popular budget brands (Six Star, Body Fortress, Premier Protein) While Claude pushes back hard on premium brand "marketing tax." This run shows the most consistent universal #1 in any category we've tracked. Optimum Nutrition has won every single prompt across every model.
Top Brands by AI Mention Frequency
Mention frequency counts how many times a brand appeared across all AI responses. This differs from top-pick rank, which reflects each model’s #1 choice.
Why These Brands Win
- All 4 models recommend whey isolate as the default for active 4-5x/week trainers.
- Every model emphasizes 24-30g protein per serving as the target.
- All flag third-party testing (NSF Certified for Sport, Informed Choice) as the quality marker that matters.
- Budget prompts universally feature Optimum Nutrition, Dymatize, Nutricost, or Body Fortress.
- Models agree consistency matters more than premium brand selection.

How we measure this
Each benchmark runs the same standardized prompts across multiple leading AI systems, including ChatGPT, Claude, Gemini, and Perplexity. We use consistent, category-specific questions designed to surface genuine product recommendations — not sponsored results.
Responses are parsed to extract brand mentions, rank position, and frequency. We then analyze cross-model agreement, identify which brands consistently appear in top positions, and flag where AI outputs diverge from marketplace trends.
Evergreen categories are benchmarked monthly. Results reflect organic AI behavior at the time of testing. Read the full methodology
Your competitors are showing up in AI results. Are you?
The protein powder market is locked at the top by Optimum Nutrition (universal #1 in 12 of 12 prompts) and Dymatize (universal isolate pick). Nutricost has gained Claude-specific authority. Major retail brands like Vital Proteins, BSN, Cellucor, Ghost, and Garden of Life have minimal AI visibility despite real retail presence. Premium boutique brands like Promix and Thorne have meaningful single-model presence but zero cross-model authority. If your protein brand isn't Optimum Nutrition, Dymatize, or Transparent Labs, you're fighting for fragmented per-model visibility. And Claude's "you're paying for marketing" framing makes premium positioning especially hard.
