Cheaply made vitamins are an issue(rip off) and are primarily riding on the back of good well made supplements which you see in published studies. People take vitamins because of some advertisement citing published studies or from a verbal or expert recommendation. But getting pharmaceutical grade supplements that have gotten positive published results is a buyer beware proposition that requires the person to ask questions and to do some research. Pharmaceutical grade are well made and tested so you would expect to pay more. But paying more is no guarantee. Generally you want to see if the supplement has 3rd party certification like GMP, ISO etc and also if you can talk to them too establish what they are like or trustworthiness and how and where they source their ingredients and if they test for contaminants . But it should be kept in perspective that even though it is fairly unregulated it is not recording any deaths as published in US Poison Control Center and yet it seems counter intuitive that under the most regulated regime there are quite a few.
