Verify if supplements, vitamins, and products have been independently tested by NSF, USP, ConsumerLab, and other trusted labs.
Check Product Testing FreeThird-party testing means an independent laboratory — not the company that made the product — has tested it to verify what's actually inside. This matters because:
Tests for label accuracy, contaminants, and banned substances. Includes NSF Certified for Sport.
United States Pharmacopeia verifies identity, strength, purity, and manufacturing standards.
Independent testing of health and nutrition products for quality and label accuracy.
UL testing, Informed Sport certification, and other independent testing bodies.
Step 1: Go to productscans.com
Step 2: Enter the product barcode or scan the label with your camera
Step 3: View the "3rd Party Testing" section in your results
If testing info is found, you'll see the testing organization, test results, and certifications. If no testing info is found, Product Scans will tell you that too — which is important information when choosing between products.
What does 3rd party tested mean?
It means an independent lab (not the manufacturer) has verified the product's contents, purity, and potency. Common testing organizations include NSF, USP, and ConsumerLab.
Does 3rd party tested mean safe?
3rd party testing verifies what's in the product matches the label and checks for contaminants. It's the strongest independent verification available, though it doesn't guarantee the product is right for every individual.
Why don't all supplements get 3rd party tested?
Testing is voluntary and expensive. Companies must pay for testing and meet strict quality standards. Products that pass earn the certification — products that don't test may have something to hide.
How do I know if a brand is trustworthy?
Look for 3rd party testing certifications (NSF, USP, ConsumerLab), check for FDA recalls, and scan the ingredient list for red flags. Product Scans does all three in a single scan.
