Associations between Clinically-Diagnosed Medical Conditions and Dietary Supplement Use: The US Military Dietary Supplement Use Study.

Users in many DS categories had a greater number of CDMCs, but protein/AA users had fewer CDMCs; results for combination products were mixed. These data indicate those with certain CDMCs were also users in some DS categories, especially individual vitamins/minerals, herbals, and MVM. Data are consistent with the use of DSs to enhance health, especially in those with CDMCs. Protein/AA and combination product users were more likely to be younger, more physically active men, factors that likely reduced CDMCs.
