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.

What This Means
- ChatGPT is the broadest brand surface and the most willing to give a flat numeric ranking.
- Claude is the most aggressive at refusing the supplement frame entirely - P1 named zero supplement brands and pushed toward HRT and Menopause Society certified clinicians.
- Gemini is the only model to recommend a clinician-personality brand (The Pause Life Pause Sleep by Dr.
- Mary Claire Haver) at #1 and is the most ingredient-formulation-detailed (calling out Albion magnesium, AlphaWave L-theanine, MicroActive sustained-release melatonin by ingredient brand).
- Perplexity is the most clinical and the most willing to leave answers brand-free - P1 and P2 named zero supplement brands.
- Across all four models the strongest cross-cutting move is pushing the user away from supplements toward HRT or CBT-I.
Findings and Limitations
- Mid-price perimenopause-specific DTC brands beyond Bonafide, Health & Her, Better Night, and The Pause Life are nearly absent.
- Adaptogen-specialty brands (Gaia Herbs, MegaFood, Garden of Life) underperform in the sleep-supplement context despite strong supplement category share.
- Glycine-specific brands do not surface despite Perplexity recommending the ingredient.
- CBT-I app/program brands (Sleepio, Somryst) are not positioned as alternatives even when CBT-I is recommended.
Recurring themes in the answers
- Magnesium glycinate or bisglycinate as the hero ingredient, third-party testing claims (USP/NSF/ConsumerLab), single-ingredient minimalism positioning, and a clear price point under $40/month are the recurring traits of top-ranked picks.
- Hot-flash subcategory hero ingredient is consistently Rhapontic Rhubarb (ERr 731) or Black Cohosh.
- Hero SKUs: Thorne Magnesium Bisglycinate, Pure Encapsulations Magnesium Glycinate, Estroven Sleep Cool, Bonafide Relizen.

Claude P1: Pushed back hard on the framing. Recommends HRT, low-dose oral micronized progesterone (Prometrium), or non-hormonal Rx (SSRIs, gabapentin, fezolinetant Veozah). Mentions magnesium glycinate as the only supplement with cleanest evidence-to-side-effect ratio. No specific supplement brands named.
