Pursued by Protandim Proselytizers

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 me personally. I have ignored the Internet attacks, but I’m beginning to feel personally harassed: I have lost count of the e-mails I have received from Protandim enthusiasts trying to convince me that it works and that I should change my mind. I’ve spent hours trying to explain my reasoning in e-mails, and it’s becoming a repetitive chore, so I am writing this so that next time I get an e-mail inquiry I can simply forward this link.

What Is In It?

Protandim is a mixture of milk thistle, bacopa extract, ashwagandha, green tea extract, and turmeric extract (all of which, incidentally, can be purchased individually at much lower cost).

What Do They Claim It Does?

As described on Wikipedia:

The manufacturers of Protandim claim the product can indirectly increase antioxidant activity by up-regulating endogenous antioxidant factors such as the enzymes superoxide dismutase (SOD) and catalase, as well as the tripeptide glutathione, and by activation of theNrf2 pathway.

Nrf2 is a transcription factor that upregulates the expression of various genes that may regulate oxidative stress. Drugs to target that pathway might have benefits for diseases that are caused or exacerbated by oxidative stress. Such drugs are investigational at this point, but the makers of Protandim have skipped the investigational stage and are marketing a product that they think is effective for almost every ailment known to man and that they are promoting as an anti-aging supplement.
