USANA Health Claims Database


Between March and November 2016, the Direct Selling Association (DSA) listed 62 DSA-member companies selling nutritional supplements. TINA.org investigated each one of these companies and found that 60 of them (or 97%) have made or are making — either directly or through their distributors — claims that the companies’ products (which include supplements, as well as devices, clothing, and skin care products) can treat, cure, prevent, alleviate the symptoms of, or reduce the risk of developing diseases or disorders, in violation of the law.

Below is a sampling of TINA.org’s findings for USANA Health Sciences. TINA.org notified USANA of these findings in November 2016.

In 2021, TINA.org found additional unsubstantiated health claims regarding USANA products. Those findings are listed below TINA.org’s original 2016 findings.

*TINA.org audited these findings in November 2021. Any URLs or inappropriate health claims that had been taken down as of that time are shown below in gray.
