Vitamins, minerals and amino acids form the brick-and-mortar foundation of a healthy body. The 2015 Dietary Guidelines Advisory Committee reported that many Americans fall short in obtaining sufficient quantities of these important nutrients, including vitamins A, C, D and E, folate, calcium, magnesium, potassium and fiber. Also, the prevalence of insufficient nutrient intake tends to increase with age. Thirty-five to 40 percent of older adults who do not take supplements have inadequate B-6 intake, and older adults often have difficulty obtaining enough B-12 from their diet. Supplementation with vitamins, minerals and amino acids can play a valuable role in helping to fill these gaps.
