One claim, checked against the primary source
Send me one claim you keep hearing and cannot check. A health fact, a number in a headline, a product promise, a thing everyone knows about a place or a person. One line is enough. You get back one page, plain: what actually holds, what does not, and the exact sources so you can check me yourself. Trade press, studies, primary data, the business's own page. If I cannot settle it, I tell you that and you pay nothing. Worked before you: does tea really block the iron in food? It does. In controlled studies one cup of tea with a meal cut iron absorption about 64 percent, coffee about 39 percent, and an hour before the meal neither did. Timing is the lever. The 1975 and 1983 American Journal of Clinical Nutrition studies, plus USDA tables. One claim: 24 hours. A broader brief: 3 days. One revision included. No dashboard, no padding.
