Nutritional needs change substantially with aging — yet most dietary guidance is derived from younger adult populations. Adults over 60 face a convergence of physiological changes that increase nutritional risk: reduced appetite and caloric intake; impaired absorption of specific nutrients (B12, vitamin D, calcium, iron); increased protein requirements for sarcopenia prevention; and higher prevalence of medications that interfere with nutrient absorption (PPIs, metformin, statins). Appropriate nutritional support in older adults is not supplementary to clinical care — it is a clinical intervention with direct impact on function, hospitalization rates, and mortality. Our clinical nutrition catalog includes oral nutritional supplements and targeted nutrient products for older adult populations.
Protein: The Most Critical Macronutrient Priority
The RDA protein recommendation (0.8g/kg/day) was established in younger adults and is inadequate for older adults facing anabolic resistance and sarcopenia risk. ESPEN recommends 1.2–1.6g/kg/day for healthy older adults and 1.5–2.0g/kg/day for those with illness or injury. Distributing protein evenly across 3–4 meals (25–40g per meal) maximizes muscle protein synthetic response through repeated leucine threshold stimulation. High-protein oral nutritional supplements (Ensure High Protein, Boost High Protein, Isosource) are particularly useful for older adults who cannot meet protein targets through food alone. Our nutrition catalog carries the full Nestlé and Abbott clinical nutrition lines for facility and patient home use.
Critical Micronutrient Priorities
Vitamin B12: atrophic gastritis affects 10–30% of adults over 60, reducing intrinsic factor and consequently B12 absorption from food-bound B12. Supplemental B12 (cyanocobalamin or methylcobalamin) bypasses this absorption impairment since free B12 is absorbed passively without requiring intrinsic factor — making supplementation effective where dietary B12 is not. Monitoring: serum B12 plus methylmalonic acid and homocysteine provide the most sensitive detection of functional B12 deficiency. Vitamin D: synthesis from sunlight is 75% reduced in adults over 70; combined with lower outdoor activity and dietary intake, vitamin D deficiency affects 35–40% of older adults. Supplementation targeting serum 25(OH)D of 40–60 ng/mL requires 1000–2000 IU/day for most older adults. Calcium: adequate intake with vitamin D supports bone density maintenance — 1000–1200mg/day total (dietary + supplement). Lab testing supplies for micronutrient monitoring are in our laboratory section.
