The Medical Letter recently evaluated “bioidentical” hormones and concluded
There is no acceptable evidence that “bioidentical” hormones are safe or effective. Patients should be discouraged from taking them.
“Bioidenticals” include progesterone, estrogens (estriol, estradiol, and estrone), and testosterone. They have mainly been promoted as a safer, more natural alternative to menopausal hormone replacement therapy (HRT), but they are also claimed to increase energy, well-being, and quality of life, and to have an anti-aging effect. Suzanne Somers recommends them for all age groups and both sexes. There is no evidence to support any of those claims.
The whole “bioidentical” thing is a pseudoscientific concept: it is a marketing term rather than a scientifically meaningful one. Bioidenticals are promoted by celebrities like Suzanne Somers, a few maverick medical doctors like Kent Holtorf, proponents of “natural” medicine, patients who were frightened by the Women’s Health Initiative study of hormone replacement therapy, and critics of Big Pharma. The mainstream scientific community is in consensus: a number of medical organizations, from the American Cancer Society to the Mayo Clinic, have issued statements similar to that of The Medical Letter.
If there’s one thing I’ve become utterly disgusted with in the time since I first became interested in science-based medicine as a concept, its promotion, and the refutation of quackery and medical pseudoscience, it’s empty-brained celebrities with an agenda. Be it from imbibing the atmosphere within the bubble of woo-friendly southern California or taking a crash course at the University of Google and, through the arrogance of ignorance, concluding that they know more than scientists who have devoted their lives to studying a problem, celebrities believing in and credulously promoting pseudoscience present a special problem because of the oversized soapboxes they command. Examples abound. There’s Bill Maher promoting anti-vaccine pseudoscience, germ theory denialism, and cancer quackery on his show Real Time with Bill Maher and getting the Richard Dawkins Award from the Atheist Alliance International in spite of his antiscience stances on vaccines and what he sneeringly calls “Western medicine.” Then there are, of course, the current public faces of the anti-vaccine movement, Jenny McCarthy and her boyfriend Jim Carrey, the former of whom thinks it’s just hunky dory (or at least doesn’t appear to be the least bit troubled) that her efforts are contributing to the return of vaccine-preventable infectious diseases because she apparently thinks that’s what it will take to make the pharmaceutical companies change their “shit” product (her words), and the latter of whom spreads conspiracy theories about vaccines and contempt on people suffering from restless leg syndrome. Finally, there’s the grand macher of celebrity woo promotion, Oprah Winfrey, who routinely promotes all manner of medical pseudoscience, be it “bioidentical” hormones, the myth that vaccines cause autism (even hiring Jenny McCarthy to do a blog and develop a talk show for her company Harpo Productions), or other nonsense, such as Christiane Northrup urging Oprah viewers to focus their qi to their vaginas for better sex.
Unfortunately, last week the latest celebrity know-nothing to promote health misinformation released a brand new book and has been all over the airwaves, including The Today Show, Larry King Live, and elsewhere promoting it. Yes, I’m talking about Suzanne Somers, formerly known for her testimonial of having “rejected chemotherapy and tamoxifen” for her breast cancer, as well as her promotion of “bioidentical hormones,” various exercise devices such as the Thighmaster and all manner of supplements. Her book is entitled Knockout: Interviews with Doctors Who Are Curing Cancer–And How to Prevent Getting It in the First Place. It is described on the Random House website thusly:
No doubt you’ve come across them before, either on the Internet, printed advertisements, or radio and TV ads: Alternative medicine cancer “testimonials.” They are the primary means by which “alternative” therapies for cancer (or just about any other disease) are promoted and the primary “evidence” that is used to “prove” the efficacy of non-evidence-based therapies. There’s no doubt that they sure can sound convincing. Typically, what you will see or hear is a chipper-looking and -sounding person who claims that this treatment “cured” his or her cancer. These testimonials almost always include many or all of these elements: First, the cancer patient receives the diagnosis, after which she is lost and suffering at the hands of “conventional” doctors, who either cannot or do not wish to understand and who cannot do anything for her. Often, this will take the form of the classic alt-med cliche that the patient was “sent home to die.” Then, when all hope seems lost, the patient discovers an alternative medicine “healer” or treatment. It is not infrequently described in quasireligious terms, like a revelation or something that brings the patient out of the darkness and into the light. Naturally, there is resistance from the patient’s doctors, family, and/or friends, who warn against it, with doctors warning of dire consequences if the patient abandons conventional medicine. But the patient, convinced by dubious practitioners, friends, and, of course, previous testimonials, “sees” that the treatment “works” in a way that medical science cannot and survives. Infused with fervor, the patient now wants to spread the word. Often, the patient is now selling the remedy. Perhaps you’ve seen such testimonials or heard them on the radio and thought: “Gee, this sounds great. I wonder if it works.”
The answer is: Almost certainly not.
