Key Insights
Key Takeaway
For a 42-year-old perimenopausal sleep buyer, AI recommendations consolidate around two practitioner-grade brands - Thorne and Pure Encapsulations - for the single-ingredient magnesium glycinate slot. Estroven owns the hot-flash blend slot. The strongest cross-model signal is that AI models are systematically steering away from supplement-only solutions and toward HRT consultations with menopause-certified clinicians - this represents a category-level headwind for any supplement brand depending on AI recommendation for growth.
Top Brands Summary
Thorne, Pure Encapsulations, NOW Foods, and Estroven form the universal-tier core - mentioned across multiple models. Thorne and Pure Encapsulations dominate the practitioner-grade magnesium glycinate slot (both appear in ChatGPT, Claude, Gemini, and Perplexity). Estroven owns the hot-flash / menopause-blend consensus position (3 of 4 models). Nordic Naturals, OLLY, and Nature Made form a clear second tier. The Pause Life (Dr. Mary Claire Haver) is Gemini-only at the top but signals the rise of clinician-personality brands.
