Our Review Process

Every ConsumerSun guide starts from primary sources: the product label or spec sheet, the published research, and official guidance such as the NIH Office of Dietary Supplements, the FDA and the FTC. We check claims against those sources, show our reasoning, and say plainly when the evidence is thin or mixed. We compare cost per serving, per use or per month rather than per package, and we note independent certification (such as USP, NSF or Informed Choice) where a manufacturer has it and where it doesn't. We do not run laboratory tests, and an article will only say a product was tested if we actually tested it. Health articles do not give medical advice or make disease claims. No brand pays to be included, ranked or reviewed. Articles are dated, reviewed when products or research change, and corrected openly when we get something wrong.
