Agreed Jules.
Note on Mercola in general:
Mercola has run afoul of the FDA many times and has been recently ordered to stop making unsubstantiated claims for products sold on his website. Additionally, having identified himself a 'renegade' doctor, he makes many baseless statements about health that are routinely challenged and debunked, hoping to appeal to the faction of patients who feel they aren't getting the results they desperately seek from the traditional medical community.

Think what you will of the FDA (I myself am critical of them but moreso Mercola - google quackwatch.com) but they are the only agency standing between us and the people who sell 'miracle' cures that don't work, or worse yet - harm us.

I'm sure you know this already but if you're a Mercola fan, seek multiple sources to validate the information he provides: some of its harmless, some of its valid, some of it's not.
