Not all supplements are safe either depending on what else you are taking and on what's in the supplement. That's why you let your doctor know everything that you are taking.

And the companies that make supplements are making mega bucks. Go into any store where they sell supplements and there are rows and rows of them; not to mention the ones sold on-line.

That's not to say that the companies who make prescription drugs aren't making money because they are. Also it costs them mega bucks to put a drug out there. That would be just one reason why there is no cure/treatment at the moment for CMT and other diseases which are considered orphan diseases.
