Why was this study done?
Diet and nutrition play important roles in health prevention and maintenance. Dietary supplements are thought to fill nutritional gaps to help support overall health. This study was designed to help determine the relationship between supplemental use and measurements of overall health.

What did the study find?
Long-term supplement users (multivitamin/mineral, extra vitamin C and B vitamins, Omega-3) were more likely to have optimal levels of blood nutrients, lower blood pressure, less diabetes, lower homocysteine, C-reactive protein, higher HDL, and lower triglyceride levels than non-supplemental users.
