When testing supplements, ConsumerLab.com uses rigorous independent testing to determine the product's strength, purity, and disintegration--specifically for Procosa, ConsumerLab tested its glucosamine content, how it met stringent lead levels criteria and its ability to disintegrate or break apart.
"In 20 years of doing business, we've never had to issue a product recall," said Jim Brown, USANA's vice president of global operations. "Because we manufacture over 90% of our products in-house in our FDA-registered facility, we can control the quality, safety and efficacy of our supplements. We also insist that our vendors follow our same strict quality control processes, so that by the time our product is shipped out, it has been tested numerous times."
"We welcome any third-party organization, such as ConsumerLab.com, to test and verify the claims we make on our products," says Dan Macuga, USANA's chief communications officer. "It gives us the opportunity to prove the claims we've been making for years on products that are now sold in 18 markets worldwide. All USANA employees are given free products monthly, so we are both the manufacturers and the end users of our own supplements. We are very committed to our products."
In addition to earning ConsumerLab.com's seals of approval, USANA's products, which are used by over 600 professional athletes, are also independently tested by NSF International and HFL. The company's Utah-based manufacturing facility follows Federal Drug Administration (FDA) guidelines for Good Manufacturing Practices (GMP) and voluntarily tests its supplements to make sure they meet United States Pharmacopeia (USP) standards and specifications for potency, uniformity, and disintegration.
