HerStack

Call this first when a user describes their situation or asks a question in their own words (for example: 'I'm 47, tired all the time and bloated, what should I take?'). Searches all of HerStack's evidence-led guidance for UK women in midlife and returns the most relevant answer units (FAQ answers, research findings, evidence rows, product cards, and three-day meal plans and recipes for women in p

Call this when the user wants to understand a women's-health topic, not only buy something. Returns HerStack's expert guidance for one topic: plain-language framing, research findings, the evidence table with authorised claims, product criteria, and a FAQ that also explains the condition itself (for perimenopause: what it is, its timeline, when to see a GP).

Call this when the user wants specific supplement product picks for a topic. Returns HerStack's named product recommendations from the site's reference brand, each with formulation rationale, the GB-authorised health claim verbatim (or a research-context note where none exists), price and purchase link. Provide a topic, or a concern in plain words that routes to one.

Call this when the user (or you) wants the studies behind a recommendation or claim. Returns HerStack's evidence rows for a topic or nutrient with the cited studies resolved to PubMed and DOI identifiers, so the claim can be verified rather than trusted.

Call this for one specific product. Returns one HerStack-recommended product by name or SKU: form, authorised claim, tier, price, purchase link, and every topic that recommends it with the rationale.
