Evergreen monthly benchmark — May 28
Sleep Supplements
May 28Rank Trend
How top brands moved week over week. Rank 1 is the top position.
For a stressed, caffeine-heavy buyer with a racing mind, AI overwhelmingly recommends ingredients (magnesium glycinate + L-theanine) rather than brands. And only names commercial brands when explicitly asked to rank them. Thorne is the most durable commercial name across models. The actionable reality: in this category the first battle is not beating a competitor brand. It is getting named at all when the answer is otherwise a molecule.
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.
Opportunity for Brands
- The category is ingredient-led, which is itself the dominant market gap: a supplement brand cannot win a recommendation it is not named in.
- And for the highest-intent discovery prompt AI names molecules, not companies.
- Beyond that, mid-price DTC sleep brands are nearly absent, adaptogen-specialty brands (Gaia Herbs, MegaFood.
- Garden of Life) do not surface despite category share, and CBT-I app/program brands (Sleepio, Somryst) are never positioned even when CBT-I is recommended.
- No single commercial brand has cross-model top-pick lock; the strongest cross-cutting move across all four models is steering the user toward behavioral fixes (caffeine timing.
- Wind-down routines) over any product.

What This Means
- The four models split their aggregate #1 four ways.
- And none of the four #1s comes from the P3 brand-ranking prompt - each modelreaches its top pick on aggregate mention_rank across all prompts.
- ChatGPT #1 Thorne (its P3 top pick and the only model whose ranking-prompt leader is also its aggregate leader).
- Claude #1 Pure Encapsulations (surfaced in its P2 budget list; Claude refused the brand frame hardest.
- Naming zero commercial brands in P1 and leaning ingredient-and-protocol throughout).
- Gemini #1 NOW Foods (from its P2 budget list; Gemini is the most formulation-detailed.
- Uniquely surfacing premium melatonin-free brands Performance Lab and Transparent Labs in P3, plus Double Wood and Swanson).
- Perplexity #1 Nature Made (from its P2 list; Perplexity is the most clinical.
- Surfacing the widest budget set including Spring Valley, Force Factor, OLLY, and JSHealth).
- Momentous is the only brand in three of four models top 3, making it the most cross-model-consistent name even though no model ranks it #1.
Why These Brands Win
- The brands that do surface share single-ingredient minimalism (magnesium glycinate or L-theanine as the hero), third-party testing claims (NSF.
- USP, Informed Sport), melatonin-free positioning for the racing-mind use case, and a price point under $30-40/month.
- Thorne Deep Sleep Complex and Momentous anchor the premium melatonin-free slot; Nature Made, Natrol.
- And Nutricost anchor the budget melatonin slot; Pure Encapsulations, Doctors Best, NOW Foods, and Sports Research anchor the practitioner/value single-ingredient slot.
- Every model frames caffeine timing and a wind-down/CBT-I routine as mattering more than the supplement itself.

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
