Mercola's medical claims have been criticized by the medical, scientific, regulatory, and business communities. A 2006 BusinessWeek editorial stated his marketing practices relied on "slick promotion, clever use of information, and scare tactics". In 2005, 2006, 2011, and 2021 the U.S. Food and Drug Administration (FDA) warned Mercola and his company that they were making illegal claims for their products' ability to detect, prevent, and treat disease.

Quackwatch has criticized Mercola for making "unsubstantiated claims [that] clash with those of leading medical and public health organizations and many unsubstantiated recommendations for dietary supplements". Of Mercola's marketing techniques, surgical oncologist David Gorski says it "mixes the boring, sensible health advice with pseudoscientific advice in such a way that it's hard for someone without a medical background to figure out which is which".
