Erin Delaney is a health science journalist who has spent nine years reading the documents behind health product marketing. She covers dietary supplements, wellness devices and the advertising rules that govern them, working from FDA and FTC filings, NIH Office of Dietary Supplements fact sheets, USP and NSF standards and the primary research literature rather than press releases or vendor claims. Her interest started with one question that nobody on a product page ever answers: if the bottle says clinically proven, who actually checked, and against what? She is not a physician and does not give medical advice. Her job is to show you what the evidence says, and to be equally clear about where it runs out.
