Hi Product Hunt! I'm John, founder of supp.fit. Most supplement claims rest on animal studies, lab tests or marketing. I wanted one place that shows only what randomized controlled trials found, with the paper behind each claim. What you can do: - Search a supplement (vitamin D, magnesium, ashwagandha) or a goal (sleep, energy, immunity). - See each benefit graded by evidence strength: how many trials and how many participants. - Open the PubMed study behind every claim. - Rank My Stack: take one photo of your supplement shelf, and supp.fit matches the bottles to 400K+ products. - Ask your AI assistant: the MCP server (mcp.supp.fit) gives Claude and ChatGPT the same evidence. Browsing the evidence is free. I'd love your feedback: which supplement or goal should we cover better? For information only, not medical advice.
