It was the US Surgeon General who suggested and started up regulation of vitamins and food supplements due to the problems caused by them. The outcry from the New Age Health Companies was very nasty and vicious...the Government wants to take control of your essential vitamins and supplements... So the Surgeon General walked away from his scientific position and just let companies do what they like and state what they like...thus the present world wide market. These early years of the 21st Century are best noted as the time when human reason, governance responsibility, and scientific analysis, gave way to market forces and corporate power as being the social 'truth'. For those interested, the US Surgeon General noted that Vitamin D could be sometimes useful for health if one was living in Arctic regions, and Vitamin B was close to the placebo effect regarding support for massive mis-use of alcohol, but the rest of the vitamins and minerals and supplements were best avoided as they were not real human food and they could cause significant health problems. But who wants to know that? We live in a new Dark Ages.
