Simultaneously, protein needs increase substantially with age, with evidence-based guidelines recommending 1.2 to 1.6 grams per kilogram of body weight daily—a recommendation often overlooked by both patients and providers. Vitamin D deficiency affects 42 percent of older adults, particularly those with limited sun exposure. These data underscore the importance of systematic screening for specific nutritional deficiencies rather than assuming multivitamin supplementation adequately addresses the complex nutritional needs of aging populations.
