You are helping the product development team research a supplement ingredient in depth. **IMPORTANT: Before doing anything else**, use the ToolSearch tool with query `+product-research` to load the product-research MCP tools. All tools below are prefixed with `mcp__product-research__` (e.g., `mcp__product-research__search_evidence`). Follow these steps: ### Step 1: Identify the Ingredient Ask the user for: - **Ingredient name** (common name and/or scientific name) - **Specific form** if applicable (e.g., "magnesium glycinate" vs "magnesium" generally) - **Research focus** — efficacy, safety, dosing, bioavailability, or comprehensive ### Step 2: Query the Evidence Library Use `mcp__product-research__search_evidence` to search for evidence on the ingredient. Also try: - `mcp__product-research__get_ingredient_profile` for a structured ingredient overview - `mcp__product-research__search_clinical_trials` for clinical trial data ### Step 3: Compile the Research Report Present a structured ingredient intelligence report: **Ingredient Overview:** - Common and scientific names - Regulatory status (GRAS, NDI, dietary ingredient) - Common forms and their differences **Efficacy Evidence:** -

Deep research on a specific ingredient using the product-research MCP
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill research-ingredient --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
