Key Insights
Key Takeaway
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 Summary
This run tracked a stressed-engineer / racing-mind persona (45yo male, heavy caffeine, work-driven insomnia) - a different buyer than the perimenopause persona of prior runs, so brand turnover this run reflects the persona, not a market shift. Thorne is the most-mentioned commercial brand, appearing across ChatGPT, Claude, and Perplexity. Momentous, Pure Encapsulations, NOW Foods, Natrol, Nature Made, and Sports Research form the recurring mid-set. The defining structural finding: this category is ingredient-led, not brand-led - across all four models the discovery prompt (P1) named ZERO commercial brands, recommending molecules (magnesium glycinate, L-theanine, low-dose melatonin, ashwagandha, apigenin) instead. Commercial brands surface reliably only when the prompt forces a brand ranking (P3).
