Even "subtle subclinical deficiencies of micronutrients and inadequate macronutrient intake contribute to a decline in immune function in the elderly" [1]. "The impaired regulation of the immune system in aging contributes to a higher morbidity and mortality from infections, autoimmune, and neoplastic diseases"[1]. Some studies show that either vitamins or minerals supplements may improve the immune function in older subjects [2-5 ]. Therefore, it is plausible to assume that improvement of their nutritional status through MVM supplements may benefit their ability to fight infections. The hormonal and physiological deregulation in aging might also benefit from MVM adding to the body effectiveness to deal with common pathogens in aging.
