The Council for Responsible Nutrition (CRN), the dietary supplement industry's leading trade association, has released its comprehensive report, The Benefits of Nutritional Supplements (4th Edition).
The updated book assesses the current state of the science on the health benefits associated with select nutritional supplements. It looks at positive studies as well as null and negative study results.
Specifically, the report addresses multivitamins, antioxidants (vitamins C and E), calcium, long chain omega-3 fatty acids (fish oils), vitamin D, vitamins B-6 and B-12, fiber and folic acid.
The report can be downloaded (individual chapters or in its entirety) at the CRN website.
