A person who describes himself as a “pseudoscience fighter” e-mailed me to chastise me for writing about Prodovite last week. He felt compelled to offer me some advice. He made some good points; but they were things I had already thought about, and they didn’t change my mind. I thought it might be useful to open
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.

Multilevel marketing distributors of dietary supplements and essential oils point to studies that they think constitute evidence that their products work.

I’m fed up! In August 2009 I wrote about Protandim, pointing out that it’s not supported by good evidence. I thought I had made myself clear; but apparently I had only made myself a target. True believers have deluged the Internet with attacks on my article, calling it mere “opinion,” ignoring its main points, and denigrating
Four years ago I received an e-mail inquiry about Protandim. I had never heard of it; but I looked it up and wrote a quick, informal, somewhat snarky answer that got posted on the Internet.
