Supplement authenticity matters for consumers who want to know what they’re getting. Supplement authenticity isn’t just about the front label; it’s about matching every element on the package to what the manufacturer states and what is verifiable elsewhere. This page covers simple steps: check labels, note batch numbers, review COAs, look for GMP seals, and consider brand trust. By using these checks, you can reduce the chance of encountering counterfeit products. Start with the label on the product bottle or pouch. Look for the exact product name and form, a complete ingredient list, serving size, and net quantity. Check the manufacturer name and contact information, the lot or batch number, expiration date, and storage instructions. Inspect the packaging for tamper-evident seals, spelling accuracy, fonts, and overall print quality. If any element seems inconsistent with the official product page, flag it as a potential red flag. Batch numbers tie a specific production run to its testing documents. When possible, obtain the Certificate of Analysis (COA) for the batch you are considering. COAs should come from an accredited third-party laboratory or the manufacturer itself and detail ingredients, potency, and contaminant testing results. Verify that the COA matches the product, batch number, and expiration date. If you cannot locate a COA or the COA lacks key details, proceed with caution or choose a different source. GMP seals indicate compliance with manufacturing standards; look for seals from recognized standards bodies and ensure the seal is current. Research the brand’s reputation by checking official websites, distributor networks, and third-party testing programs. Prefer products from brands that publish COAs, maintain transparent labeling, and participate in independent testing. Finally, compare listings across trusted retailers and official channels to confirm you are seeing the same product and batch information.
