If you can help me find a website that shows studies that have been done and the results. I thought I had come across a website like that. I am more interested in the nutritional field like finding out about gingko bilboa, green tea and etc

Thanks in advance.

Try looking at: Search Clinical Trials – Center for Information & Study on Clinical Research Participation (http://www.searchclinicaltrials.org), or google: clinical trials (name of supplement) That should do it.
