The play: WIRECUTTER FOR UK WOMEN'S SUPPLEMENTS the entire women's life-stage health + supplement universe owned by US/academic, UK fashion media, NHS at the head, and small UK private clinics — no UK women's-health authority site curates + recommends + lab-tests existing branded supplements with named-clinician sign-off across all life stages. Wild Nutrition is the 40.5k UK giant but only 110/mo on "wild nutlition menopause"; Louise Newson owns clinical-content but doesn't sell products; MyProtein/Bulk sell products but lack editorial authority. The asymmetry: the only entity that can tick all 10 trust signals (named GP + RD + coach + heavy-metals lab + EFSA + female-positioned + reviewedBy schema + UK survey + quiz + page-equals-product-recommendation) wins the AI-citation game. ~400-500k+/mo ADDRESSABLE per the agent-wave synthesis: 60.5k symptoms + 55-60k female creatine + 80k symptoms cluster + 160k worried-buyer informational + 50k magnesium authority + 15k collagen authority + 30-40k pregnancy/postnatal + 10-21k ayurveda × perimenopause.
Per the AGENT-WAVE-SYNTHESIS — addressable grew from ~320k/mo (original scope) → ~400-500k+/mo (after Agent 2 + 3 layered Magnesium + Collagen + Pregnancy/Senior + Ayurveda pillars).
