Im sure no one who manufactures, distributes, or sells suppliments is in it to make a profit they are volunteering and only trying to help others who make the mistake of thinking someone with decades of education in medicine are more qualified to help them than a neighbor who went to a few seminars. We can thank Senator Hatch for part of this. (Health & Suppliment Act 1993). Other than that legislation im a fan of his. Suppliments have caused me a lot of health problems and more than 1 person close to me stopped their treatment for a serious condition to put trust in a suppliment pitched....quickly regressed and are no longer with us.
I vehemently feel that ANY processed substance being sold that even hints it can treat a medical condition must go through extensive trials. And anyone representing it must be licensed and regulated. Not a few hrs of PowerPoint presentations and downline management training.
