Dietary and nutritional supplements can be confusing. The FDA’s Dietary Supplement Web site can clear up some of the confusion. It defines what a dietary supplement is and explains what the FDA does and does not regulate. The FDA’s site also has an “alerts” section that names specific supplements that have found to be harmful to people. For example, a couple of years ago the story of the man who turned blue after taking colloidal silver popped up in the news. It is your health-make sure you know what is going into your body!
To see what ingredients are in a specific supplement visit the Dietary Supplements Database.
