Centrum promises that by taking a daily multivitamin, people can ensure they are getting the daily recommended amounts of vitamins and minerals, and that this is particularly important as people age since older adults may eat less than when they were younger. Centrum calls their Centrum Silver multivitamins "age-adjusted" for adults who are over 50.
Special Nutritional Needs
Keeping your heart and cardiovascular system healthy becomes a priority as you age, so Centrum Silver includes lycopene and vitamins B6 and B12 to promote heart health. Saving vision by preventing cataracts and macular degeneration is also important to seniors; Centrum Silver contains added lutein and vitamins A, C and E which is said to support eye health. Extra B vitamins are added to help support the body's production of energy, which can decline with age. Centrum Silver also contains high levels of vitamin D and calcium to support bone health and help prevent osteoporosis, often a health concern in older people. Judith Stern, professor of clinical nutrition a the University of California Davis Health System, encourages seniors to take a daily multivitamin especially formulated for older adults.
