Dr. Joseph Mercola Ordered to Stop Illegal Claims | Quackwatch (2023)

Joseph Mercola, D.O., who practiced for many years in Schaumburg, Illinois, now operates one of the Internet’s largest and most trafficked health information sites. Since 2012, Mercola has stated that his site has over 300,000 pages and is visited by “millions of people each day” and that his electronic newsletter has over one million subscribers [1]. The site vigorously promotes and sells dietary supplements, many of which bear his name. It also publishes a steady stream of propaganda intended to persuade its visitors nit to trust mainstream healthcare viewpoints and consumer-protection agencies.

For many years, Dr. Mercola and other staff members saw patients at his clinic, which was called the Optimal Wellness Center. In 1999, Mercola announced that about one third of his new patients were autistic and that he had treated about 60 such children with secretin, a hormone he said “appeared to be a major breakthrough.” [2] After it was well settled that secretin is ineffective against autism [3], Mercola’s Web site still said it would work if a child complied with his recommended diet strategies [4].

In 2004, Medical Economics reported that Mercola’s practice employed 50 people and that he employed 15 people to run his newsletter, including three editors [5]. Much of his support has come from chiropractors who promote his newsletter from their Web sites. Two of his books hit the #2 sales rank on Amazon Books shortly after his newsletter plugged them for the first time. In 2017, a former employee toldThe Ringerthat most of the articles on his website were ghost written and reviewed by him [6].

In 2006, an article in Business Week concluded that he was “one of a fast-growing number of alternative-health practitioners who seek to capitalize on concerns about the conventional health care system—in his case relying on slick promotion, clever use of information, and scare tactics.” The article described how his promotions included (a) promises of “free’ to sell stuff; (a) lots of “bonuses,” (c) reports of real news that link to marginally related products, and (d) exaggerated claims. [7]

In 2012, an article in Chicago Magazine reported that Mercola had stopped practicing medicine six years previously to focus on his Web site [8]. However, his decision may have been influenced by a 3-year battle with the Illinois Department of Financial and Professional Regulation [9]. I did not see any mention of this on his Web site, and the site invited patients to come to his clinic—which was renamed Dr. Mercola’s Natural Health Center—for offbeat practices that included detoxification, chiropractic, Dispensary, Emotional Freedom Technique (EFT), Functional Medicine Program, homeopathy, Neuro-Structural Integration Technique (NST), Nutritional Typing Test, thermography, Total Body Modification (TBM), and Active Isolated Stretching.

In September 2014, Mercola announced that he had closed the clinic “in order to devote his full time and attention to research, education and increasing public awareness.” [10]

Many of Mercola’s articles make unsubstantiated claims and clash with those of leading medical and public health organizations. For example, he opposes immunization [11] fluoridation. [12], mammography [13], and the routine administration of vitamin K shots to the newborn [14,15]; claims that amalgam fillings are toxic [16]; and makes many unsubstantiated recommendations for dietary supplements. He has advised against eating many foods that the scientific community regards as healthful, such as bananas, oranges, red potatoes, white potatoes, all milk products, and almost all grains [17]. He has also given silly advice, such as minimizing exposure to electromagnetic fields by avoiding electric razors, microwaving of foods, watches with batteries [18]. Mercola’s reach has been greatly boosted by repeated promotion on the “Dr. Oz Show.”

Many of the articles he writes encourage readers to buy dietary supplements and other products that can be ordered from his companies. He has even found a way to profit from his opposition to fluoridation. In 2020, began promising that his $250“Fluoride Removal Full Spectrum Countertop Water Filters”would remove up to 99.9% of the fluoride ions from tap water. The article promoting his filters claimed that “water fluoridation is a public health scam and one of the most unnecessary and severely health-damaging practices we are exposed to today.” [19] Nothing could be further from the truth.

Mercola’s Profits

Mercola is very critical of drug company profits and proudly states:

Mercola.com does NOT accept any third-party advertising or sponsorship, and I am in no way tied into any pharmaceutical company or any other corporate “interest” whatsoever. So you get the real inside scoop on health issues, with practical advice that matters to you untainted by outside influence! [1]

He has also stated:

Mercola.com is not . . . a tool to get me a bigger house and car, or to run for Senate. I fund this site, and therefore, am not handcuffed to any advertisers, silent partners or corporate parents. . . .

Profit generated from the sale of the products I recommend goes right back into maintaining and building a better site. A site that, startling as it may be with all the greed-motivated hype out there in health care land, is truly for you [20].

Dr. Joseph Mercola Ordered to Stop Illegal Claims | Quackwatch (1)I don’t doubt Mercola’s sincerity—and I know nothing about how he allocates his income. But the BlockShopper Chicago Web site stated that in 2006 he purchased a house in South Barrington, Illinois, for $2 million and that it had 5,563 square feet. It was sold in 2016 after he had relocated to Florida. The Bing Maps aerial view indicatesthat the property is quite luxurious. His current Florida home, which he also uses as a business address, is much larger.

In 2011, Mercola announced the formation of Health Liberty, a nonprofit coalition whose goals include promoting organic foods and targeting fluoridation, vaccination, genetically modified foods, and the use of amalgam fillings [21]. In a video accompanying the announcement, Mercola stated that he planned to donate $1 million to catalyze the project. In addition to Mercola.com, the coalition members are:

  • National Vaccine Information Center (NVIC), which understates the benefits and exaggerates the risks of vaccination.
  • Fluoride Action Network (FAN), the leading promoter of misinformation about fluoridation. Its donations are funneled through the nonprofit American Environmental Health Studies Project.
  • Institute for Responsible Technology, which understates the benefits and exaggerates the risks of genetically modification of foods
  • Consumers for Dental Choice, which vigorously attacks amalgam use with misinformation, propaganda, lobbying, and lawsuits.
  • Organic Consumers Association, which irresponsibly promotes unpasteurized milk and spreads false alarms about food irradiation, agricultural biotechnology, and vaccines.

The money for the donations was funneled from Mercola.com Health Research LLC through Mercola’s nonprofit Natural Health Resources Foundation, which showed the following grants for the above groups on its tax returns:







Consumers for Dental Choice







National Vaccine Information Center







Organic Consumers Association







American Environmental Health Studies Project







Mercola’s website states that he has also given money toFood Democracy Now, the Institute for Responsible Technology, the Rabies Challenge Fund, the American Holistic Veterinary Medical Foundation, the Cornucopia Institute, the Vitamin D Council, Grassroots Health, and the Alliance for Natural Health [22].

The “health freedom” argument involves deception by misdirection. It focuses on individual freedom but does not consider how people who fail to protect their health put the rest of society at physical and/or financial risk. Failing to vaccinate, for example, decreases herd immunity so that contagious diseases spread more widely. In 2012, Mercola began calling his newsletter “Health Liberty Newsletter.”

In 2013, Williamette Week reported that Mercola had donated a total of $26,975 in cash and in-kind contributions that included polling and a YouTube video to support the efforts of the antifluoridation group that is opposing a fluoridation referendum in Portland, Oregon. The report also stated that “Mercola has questioned whether HIV causes AIDS, suggests that many cancers can be cured by baking soda, and warns parents not to vaccinate their children. He also says that animals are psychic.” [23]

The Washington Post has reported that by 2010, Mercola’s businesses were generating $3 million a month and that in 2017, he indicated that his net worth was over $100 million [24].

Mercola lives with Erin Elizabeth, whose health-related views and activities are similar to his and describes herself as “a long-term health nut, author, and public speaker.”

Better Business Bureau Reports

Mercola markets his supplements through Mercola Health Resources, LLC. In 2011, after a customer complained that she thought a product she purchased was overpriced, I began checking whether the Better Business Bureau had received any complaints. I found that the company was rated C- on a scale of A+ through F. On February 1, 2012, the BBB reported that during the previous 36 months, there were 26 complaints—which is not an unusually high number for a high-volume business—but the report contained the following comments:

A recent review of consumer complaints filed with the BBB of Chicago & Northern Illinois against your Mercola Health Resources, LLC delineates a pattern of consumer allegations. Consumers are alleging that Mercola Health Resources does not honor the 100% money-back guarantee listed on your website. Customers have reported that refunds have not been provided for returns that were specifically covered under this guarantee. Consumers have also reported that they have experienced delivery issues. While www.mercola.com states that orders ship within 10 business days, consumers say they have waited much longer for their products. Customers allege that the company’s service staff has been unable to provide explanations regarding this delay. Some consumers have also reported that Mercola provided them with shipment tracking numbers that were not valid with their respective carriers [25].

On November 26, 2013, I checked again and found that during the previous 36 months there had been 34 complaints, but Mercola Health Resources was rated A+. In September 2015, I checked and found that there had been 10 complaints but the rating remained A+. In January 2017, I checked again and found there had been 5 complaints and the rating was A-. In July 2020, I checked again and found that there had been no complaints and the rating was A+.

FDA Warnings

In 2005, the FDA ordered Mercola and his Optimal Wellness Center to stop making illegal claims for products sold through his Web site [26]. The claims to which the FDA objected involved three products:

  • Living Fuel Rx, claimed to offer an “exceptional countermeasure” against cancer, cardiovascular disease, diabetes, autoimmune diseases, etc.
  • Tropical Traditions Virgin Coconut Oil, claimed to reduce the risk of heart disease and has beneficial effects against Crohn’s disease, irritable bowel syndrome, and many infectious agents
  • Chlorella, claimed to fight cancer and normalize blood pressure.

In 2006, the FDA sent Mercola and his center a second warning that was based on product labels collected during an inspection at his facility and on claims made on the Optimum Wellness Center Web site [27]. This time the claims to which the FDA objected involve four products:

  • Vibrant Health Research Chlorella XP, claimed to “help to virtually eliminate your risk of developing cancer in the future.”
  • Fresh Shores Extra Virgin Coconut Oil, claimed to reduce the risk of heart disease, cancer, and degenerative diseases.
  • Momentum Health Products Vitamin K2, possibly useful in treating certain kinds of cancer and Alzheimer’s disease.
  • Momentum Health Products Cardio Essentials Nattokinase NSK-SD, claimed to be “a much safer and effective option than aspirin and other pharmaceutical agents to treating heart disease.”

The warning letters explained that the use of such claims in the marketing of these products violates the Federal Food Drug and Cosmetic Act, which bans unapproved claims for products that are intended for curing, mitigating, treating, or preventing diseases. (Intended use can be established through product labels, catalogs, brochures, tapes, Web sites, or other circumstances surrounding the distribution of the product.)

In 2011, the FDA ordered Mercola to stop making claims for thermography that go beyond what the equipment he uses (Medtherm2000 infrared camera) was cleared for. The warning letter said that statements on Mercola’s site improperly imply that the Meditherm camera can be used alone to diagnose or screen for various diseases or conditions associated with the breast, they also represent that the sensitivity of the Meditherm Med2000 Telethermographic camera is greater than that of machines used in mammography. The statements to which the FDA objected included:

(Video) Vandana Shiva: Bill Gates’s Book Is Rubbish!

  • “Revolutionary and Safe Diagnostic Tool Detects Hidden Inflammation: Thermography”
  • “The Newest Safe Cancer Screening Tool”
  • “[b]ecause measuring inflammation through thermal imaging is a proactive, preventative method you can use for detecting disease, which significantly improves your chances for longevity and good health.”
  • Additionally, thermograms provide: “Reliable and accurate information for diagnosis, treatment, and prognosis. . .”
  • “Yes, it’s true. Thermograms provide you with early diagnosis and treatment assistance in such problems as cancer, inflammatory processes, neurological and vascular dysfunction, and musculoskeletal injury.”
  • Thermography can benefit patients by detecting conditions including: Arthritis: “[d]ifferentiate between osteoarthritis and more severe forms like rheumatoid.” Immune Dysfunction, Fibromyalgia and Chronic Fatigue, “Digestive Disorders: Irritable bowel syndrome, diverticulitis, and Crohn’s disease . . .” and “Other Conditions: including bursitis, herniated discs, ligament or muscle tear, lupus, nerve problems, whiplash, stroke screening, cancer and many, many others.” [28]

In 2011, the Chicago Tribune reported that Mercola had not complied with the FDA’s order and intended to “fight the FDA . . . if they decide to take it further.” [29 However, in 2012, the Illinois Department of Financial and Professional Regulation asked Mercola to attend an informal conference to discuss a complaint that he was “making deceptive claims promoting thermography as a standalone diagnostic tool for detecting cancer and other diseases and is attacking the use of mammograms.” Mercola’s Web site still promotes thermography and trashes mammography, but the site stopped offering thermography appointments later that year—and Mercola’s special report, “The Safe Breast Cancer Screening Test Your Doctor Isn’t Telling You About,” is no longer apparent.

FTC Action

In 2016, Mercola, Mercola.com, LLC and Mercola.com Health Resources, settled a Federal Trade Commission complaint by agreeing to stop selling tanning beds and to pay to $5,334,067 to cover the cost of refunds and administration of the refund program. The defendants were charged with falsely claiming that their indoor tanning devices would enable consumers to slash their risk of cancer and improve the clarity, tone and texture of their skin, giving them a more youthful appearance. Commenting on the case, Jessica Rich, Director of the FTC’s Bureau of Consumer Protection, noted that indoor tanning is not safe because it increases the risk of skin cancer, including melanoma [30].

COVID-19 Response

Mercola has reacted to the COVID-19 pandemic by claiming that many of his products can boost immunity and by attacking the preventive advice given by public health agencies throughout the world. He has claimed, for example, that masks cause “oxygen deprivation” and that the mainstream recommendation for mask-wearing “has nothing to do with decreasing the spread of the virus, but more to indoctrinate you into submission.” [31] He has also encouraged “civil disobedience” in areas where mask-wearing was mandated [32] and had many articles advising against COVID-19 vaccination.

In August 2020, the Center for Science in the Public Interest and other nonprofit legal groups urged the FDA and FTC to stop Mercola from marketing at least 23 products with false claims that they can prevent or treat the disease. The letters stated:

Mercola Group has been capitalizing on the coronavirus pandemic by advising consumers to purchase vitamins, supplements, and other products sold on its website to prevent or treat the virus. Mercola Group’s website contains many misleading articles, such as “Nutrition and Natural Strategies Offer Hope Against COVID-19,” and a “Coronavirus Resource Guide” compiling various unsubstantiated claims about the COVID-fighting properties of various supplements. It also offers “medical” advice, including the extraordinarily dangerous and unsubstantiated recommendation that individuals actually try to contract COVID-19 after using the supplements it sells to ameliorate the symptoms.

Mercola Group and Dr. Mercola make multiple deceptive and unsubstantiated claims in marketing supplements and other products. The products that Mercola Group sells through its online store, and that Dr. Mercola has endorsed in public statements . . . for the prevention and/or treatment of COVID-19, include: vitamin C (specifically, liposomal vitamin C); vitamin D; zinc and selenium (which Mercola Group sells together); melatonin; licorice; molecular hydrogen; astaxanthin; n-acetyl cysteine; prebiotics, probiotics, and sporebiotics; saunas; ozone therapy; elderberry extract; spirulina; beta-glucan; lipoic acid; and sulforaphane [33,34].

The letters were accompanied by a chart that detailed the challenged claims [35]. In February 2021, the FDA ordered Mercola to stop suggesting on his website that“Liposomal Vitamin C,” “Liposomal Vitamin D3,” and “Quercetin and Pterostilbene Advanced” sold through his site are effective in preventing or treating COVID-19 and other viral infections [36].

In March 2021, the Center for Countering Digital Hate placed Mercola first on its list of “The Disinformation Dozen” who “do not have relevant medical expertise and have their own pockets to line, who are abusing social media platforms to misrepresent the threat of Covid and spread misinformation about the safety of vaccines.” His live-in partner, Erin Elizabeth, was listed seventh. The report also estimated that Mercola’s accounts on Facebook, Twitter, and Instagram totaled about 3.6 million followers [37]. In July 2021, The New York Times called Mercola “the most influential spreader of coronavirus misinformation online.” [38]

In my opinion, the dangerousness of his advice, the fact that millions of people take him seriously, and his funding of organizations that promote unscientific practices and/or oppose proven public health measures make him the world’s most dangerous supplier of health misinformation.
