Dietary supplement authenticity means that a product truly matches its label: the brand, the ingredients listed, the correct amounts, and the batch you receive. Focusing on dietary supplement authenticity helps shoppers avoid mislabeled or counterfeit items and makes it easier to verify what is in the package. This page provides practical tips and trusted sources to help you verify dietary supplement authenticity and choose products that align with their labeling. Practical tips include inspecting packaging for consistency and integrity, checking tamper-evident seals, and comparing typography, colors, and wording to an official version from the brand. Look closely at the lot number, expiration date, and any barcodes or QR codes, and consult the manufacturer’s site or customer service to confirm product specifics. Requesting a current Certificate of Analysis (COA) from the seller or manufacturer can provide an independent verification of the product’s listed ingredients and concentrations. Spotting counterfeit labels involves noticing misspellings, altered packaging, or unusual printing quality, as well as missing or unclear regulatory disclosures. If a price is unusually low or the distributor seems unfamiliar, proceed with extra caution. Rely on official channels or the brand’s verified platforms to confirm authenticity, and be aware that third-party verifications—such as USP Verified or NSF Certified programs—offer additional assurance, even though not every product will carry these seals. Choosing real, safe products with trusted sources means buying from reputable retailers and, when possible, directly from manufacturers. Favor brands that publish COAs and maintain transparent supply chains, and look for third-party verifications from organizations like USP, NSF, or ConsumerLab. Ensure the product labeling provides essential information such as the ingredient list, serving size, and manufacturer contact, and consult FDA recall notices or the brand’s support resources if you have any questions. This approach supports reliable dietary supplement authenticity and informed purchasing decisions.
