I always kind of wonder about these sorts of "miracle" cures. Do these extracts affect certain nutrients more than others (i.e. could you end up with a deficiency of some sort)? Might the extracts have adverse side effects? Just how healthy are these. But hey, science can look into these things.
Whoa, what if the government had a department to do this sort of public interest science and regulation? Wouldn't that be great?
