medlineplus.gov
Plain-language health information from the US National Library of Medicine.
Government-published, advertising-free pages on conditions, tests, medicines and supplements, written for patients and reviewed against the medical literature, with an explicit editorial policy about where the content comes from. Its lab-test pages are the clearest free explanation of what a result actually means. Because it is a public institution rather than a media business, nothing on it is trying to sell you a supplement.
Questions
Works the moment the page loads. No account, no email, no trial. It is US-oriented reference material and deliberately general — it does not diagnose, and it is no substitute for seeing a clinician.
