Try the PLOS website Public Library of Science for research, then look into iTunes, I have found some video chats regarding supplements there that are forth coming with some research results. Also you might want to join Consumer Labs ConsumerLab.com - independent tests and reviews of vitamin, mineral, and herbal supplements They offer test results and comparisons on different brands. Bottom line like mentioned above you are not going to find anyone doing this deep of research becasue the money is not there! But soon the money will be there to make sure you pay out the nose for any vitamins you do want if the FDA and the big Pharma get their way..just look at Europe!
Granted most vitamins can be gained through proper nutrition, doesn't mean a liitle help isn't needed. Placebo effect impacts our lives more than we think!
