I Was Wrong about Protandim

A seriously flawed Protandim study seemed to show that side effects were no more common than with placebo. Actually, they were almost twice as common. The researchers were looking at the wrong numbers and didn’t even add correctly. I have written about Protandim several times. In May, 2017, I said that while there was no evidence from human studies that

Update on ASEA, Protandim, and dōTERRA

Multilevel marketing distributors of dietary supplements and essential oils point to studies that they think constitute evidence that their products work. They don’t understand why those studies are inadequate. I have written critiques of several dietary supplements sold through multilevel marketing (MLM) schemes, and they keep coming back to haunt me. I get testimonials from


Introduction Homeopathy is a system of health care that was originated in 1796 by a single individual, Samuel Hahnemann, a German doctor who was critical of the medicine of his time. It is a discipline practiced by homeopaths, but homeopathic remedies are also sold over the counter in pharmacies for customers to self-treat. Homeopathy is

“New vaccine replaces statins?” Not so fast!

News reports suggest new drugs may replace statins. PSCK9 inhibitors are useful, but only along with statins in high risk patients not controlled on statins alone, or for patients who can’t tolerate statins. They’re not about to replace statins. PyMOL rendering of the structure of the PCSK9 protein. Are statins obsolete? Are new drugs more effective and

AllerVarx: A Questionable Remedy for Allergic Rhinitis

AllerVarx, a new dietary supplement, claims to relieve nasal allergy symptoms, but the only “evidence” is a single disreputable clinical trial with no control group. There is no reason to try this unproven remedy when there are so many effective remedies offered by mainstream medicine. Allergic rhinitis can be treated effectively, but not with dietary

Treating Chronic Fatigue Syndrome with Cognitive Behavioral Therapy and Graded Exercise Therapy: How the PACE Trial Got It Wrong

The PACE trial found that cognitive behavioral therapy and graded exercise therapy were effective treatments for chronic fatigue syndrome and could produce recovery in 22% of patients. It seems they got it wrong. The PACE trial said graded exercise is an effective treatment for CFS. CFS patients disagree. Chronic fatigue syndrome (CFS), also known as

Stem Cells for Macular Degeneration: Meticulous Science vs. Unethical Carelessness

Rigorous scientists stabilized a patient’s macular degeneration with a cutting-edge stem cell treatment; less rigorous scientists misapplied stem cell science and left three women blind. Age-related macular degeneration (AMD) is a major cause of vision loss in people over 50. Thirty percent of us will develop it by age 75-85. There is no cure. For

Update on Testosterone Supplementation

Testosterone supplementation is a legitimate treatment for properly-diagnosed androgen deficiency, but it is being overprescribed by doctors who make exaggerated claims for it. New evidence clarifies its modest benefits and worrisome risks. Lots of men are taking testosterone supplements, some of them for good reasons and some for not-so-good reasons. There are Low-T clinics that

Re-thinking Antioxidant Supplementation for Macular Degeneration

After the AREDS trial, people with moderate to severe age-related macular degeneration were advised to take dietary supplements to slow the progression of the disease. But some experts say the trial actually showed supplements don’t work, and might even make some patients worse. Age-related macular degeneration (AMD) is a leading cause of blindness. Known risk

A Credible Placebo Control for Chiropractic Research

The research on chiropractic has been far from rigorous. One of the problems is that studies of spinal manipulation therapy (SMT) can’t be double blinded, and it is very difficult to even do single blinding. So most studies resort to non-manipulation control groups like “usual care” or “wait list” or “pain medication.” Those studies are
