Justice Catalyst Law, in cooperation with Center for Science in the Public Interest and People’s Parity Project, wrote the Food and Drug Administration and the Federal Trade Commission, urging them to bring enforcement proceedings against Joseph Mercola and his companies for marketing supplements using illegal and deceptive claims that the products could treat, cure or prevent COVID-19.

Joseph Mercola is an osteopath who is one of the leading voices of the anti-vaccine disinformation campaign in the United States. A recent report found that almost two-thirds of the anti-vaccine content circulating on leading social media sites is generated by just 12 individuals and organizations, one of whom is Mercola. Among other things, Mercola has claimed that vitamin C, vitamin D, zinc, selenium and other supplements and devices he sells can prevent, treat or cure COVID-19.

On February 18, 2021, the FDA issued a warning letter to Mercola finding that his websites and social media site marketed unapproved new drugs in violation of the Federal Food, Drug, and Cosmetic Act, and ordered him to take corrective action within 48 hours. In May 2021, Mercola announced that he would take down the offensive materials.
