# How to Identify Counterfeit Supplements and Avoid Online Scams ## Introduction Demand for dietary supplements has grown, and so has the risk of counterfeit products and online scams. Counterfeit supplements may lack active ingredients or contain harmful adulterants, which can affect health and waste money. For a detailed overview of risks and prevention steps, see this [comprehensive guide](https://www.topvitamine.com/blogs/news/identify-counterfeit-supplements-avoid-scams). ## Hidden Dangers Fake supplements can contain undeclared drugs, incorrect dosages, or contaminants. Packaging that looks similar to a known brand can still hide unsafe manufacturing practices. Awareness of these risks helps consumers prioritize verified sources and quality checks. ## Spotting Fake Vitamins Inspect labels for spelling errors, missing batch numbers, or altered logos. Verify expiration dates and look for third-party seals and clear ingredient lists. When in doubt, confirm product details on the manufacturer site such as [Topvitamine](https://www.topvitamine.com). ## Verify and Buy Safely Buy from authorized retailers and avoid offers that seem too good to be true. Check batch numbers and request certificates of analysis when available. Community notes and guides, for example on HackMD, may help; see this [Silo resource](https://hackmd.io/@topvitamins/rJ3z2MjzWl) for collaborative references. ## Tools and Resources Use third-party testers like Labdoor or ConsumerLab and consult regulatory lists for recalls. Scanner apps, QR codes, and browser safety plugins can flag suspicious sites.
