Evergreen monthly benchmark — Apr 25
Protein Powder
Apr 25The protein powder category has a clear top tier (Optimum Nutrition, Dymatize, Transparent Labs) that dominates AI recommendations across every model. Below that, the brand visibility fragments hard by AI surface. Ghost wins ChatGPT/Gemini, Nutricost wins Claude/Gemini, Legion wins Claude/ChatGPT/Perplexity. This is one of the most fragmented categories we've tracked at the secondary tier, suggesting brand-specific AI optimization is highly viable for challengers.
Rank Trend
How top brands moved week over week. Rank 1 is the top position.
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 agree whey isolate is the default for active 5-day-per-week trainers.
- Every model recommends 20-25g protein per serving as the target.
- All flag third-party testing (Informed Choice, NSF Certified for Sport) as a non-negotiable check.
- Budget prompts universally feature Optimum Nutrition, Dymatize, and a value brand (MyProtein, Nutricost, Body Fortress, Six Star).
- Models agree consistency matters more than premium brand selection.

What This Means
- ChatGPT is the most commerce-formatted with explicit prices, star ratings, and review counts.
- And uniquely surfaces Body Fortress, GHOST, Premier Protein, up & up, and Isopure that other models barely mention.
- Claude is the most opinionated, calling out the under-$50 budget as too tight in 2026 And recommending alternative buying strategies (Costco membership, MyProtein sales), also uniquely flags Body Fortress as having ~15g of fillers per scoop.
- Gemini surfaces newer/lifestyle brands (Ritual, XWERKS, Muscle Milk) that don't appear in other models.
- Perplexity is the most conservative and lists Thorne, Naked Whey, and Six Star, picks no other model surfaces.

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 default), Dymatize (universal isolate pick), and Transparent Labs (universal premium pick). Major retail brands like BSN, Cellucor, Vital Proteins, and Promix are completely invisible to AI shoppers. The secondary tier (Ghost, Legion, Nutricost, MyProtein) is highly fragmented, most challenger brands appear in only 1-2 of 4 models. Meaning targeted optimization for specific AI surfaces could meaningfully shift visibility.
