What Is 3rd Party Testing?

Third-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:

Frequently Asked Questions

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.
