About

Finding safe, effective supplements sounds simple. You compare brands and prices, then pick what sounds best. Right?

Unfortunately, it’s not that easy. The reality is, poor quality and even contaminated products make it to market all the time. And there’s no way to tell by looking at the bottle.

Certifications by Nutrasource makes it easy to find products that are laboratory-tested and certified by an unbiased third party. We test products using real scientific data to make sure they are fresh, pure, and contain what is claimed on the label. Then, we post the full testing results for free on our website so you can check if a product is certified before buying.

It’s all about transparency. Look for the NutraStrong™, IFOS™, IKOS™, IAOS™, IGEN™, IPRO™, or Radioactivity Tested & Certified™ certification marks on product labels.
