Examine.com is an independent organization that provides unbiased research on supplements and nutrition. 

This site is so useful because it doesn't just reference studies related to the supplement you're looking for, it also considers other factors like study design, number of studies showing benefit, and significance of benefit. If you're looking for evidence-based information on supplementation and want to distinguish between marketing hyperbole and real world effects, check this site out.
