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.

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.

True believers have deluged the Internet with attacks on my article, calling it mere “opinion,” ignoring… read more "Pursued by Protandim Proselytizers"
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. It got a lot of attention. Googling for Protandim now brings up my critique right… read more "Protandim: Another Kind of Antioxidant"
