Thanks immisceo, I've done some more research online and decided to invest in a juicer instead.... Lol.
A site for unbiased consumer reports (I can PM you the link if you like. I'm not sure if posting it here would violate the T&C of MedHelp) states there is no reason this should work for any condition (and it makes claims about many unrelated conditions - a major red flag when determining potential efficacy) and states a strong concern that although the ingredients are listed, the amounts aren't. This is no small oversight. The consumer is owed this information as it can have bearing on whether something is beneficial or flat out unsafe. The study cited by the company is deemed to be of poor quality, so statistically meaningless.
Short answer, it seems this one is likely best filed under "save your money".
