search_guidanceCall 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 get_topic_guidanceCall this when the user wants to understand a women's-health topic, not only buy something.

Returns HerStack's named Solgar UK recommendations, each with formulation rationale, the GB-authorised health claim verbatim (or a research-context note where none exists), price and purchase link. Proviget_evidenceCall 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.get_product_detailsCall this for one specific product. Returns a HerStack-recommended Solgar UK product by name or SKU: form, authorised claim, tier, price, purchase link, and every topic that recommends it with the rationale.Recent checks
