A 2017 piece for German magazine Der Spiegel by Veit Medick indicated that two-thirds of Jones' funds derive from sales of a successful range of his own products. These products are marketed through the InfoWars website and through advertising spots on Jones' show. They include dietary supplements, toothpaste, bulletproof vests and "brain pills," which hold "an appeal for anyone who believes Armageddon is near", according to Medick.[89]
In August 2017, Californian medical company Labdoor, Inc reported on tests applied to six of Jones' dietary supplement products. These included a product named Survival Shield, which was found by Labdoor to contain only iodine, and a product named Oxy-Powder, which comprised a compound of magnesium oxide and citric acid—common ingredients in dietary supplements. Labdoor indicated no evidence of prohibited or harmful substances, but cast doubt on Infowars' marketing claims for these products, and asserted that the quantity of the ingredients in certain products would be "too low to be appropriately effective".[90][91][92]
On a 2017 segment of Last Week Tonight, host John Oliver stated that Jones spends "nearly a quarter" of his on-air time promoting products sold on his website, many of which are purported solutions to medical and economic problems claimed to be caused by the conspiracy theories described on his show.[93][94]
Jones continued this behavior during the COVID-19 pandemic. On March 12, 2020, Jones was issued a cease and desist from the Attorney General of New York, after he claimed, in complete absence of evidence, that products he sold, including colloidal silver toothpaste and dietary supplements, were an effective treatment for COVID-19.[95][96][97] The Food and Drug Administration also sent him a letter on April 9, 2020 warning that the federal government might proceed to seize the products he was marketing for COVID-19 or fine him if he continued to sell them.[98]
