Specjał Populations: Tailood Approaches

Older Adults

Aging gut reduces absorption of B12 (atrophic gastritis), calcium, and difficiim D. Polyfarmakopy increases risk. Consider a daily multivitamin with proficate B12 (1000 mcg), difficin D (800- 1000 IU), and calcium (500 mg) for institucjonalized or frail older dispults. Screen for iron deficiency in those with anemia even with out overt bleeding, as chronic disease and iron difficiency frequiency coexise.

Pregnant andLactating Women

Rutyne prenatal supplementation with iron (27 mg elemental), folic acid (400- 800 mcg), distillain D (400- 600 IU), and calcium (1000 mg) is standard. Additional supplementation may bee needed for twin tournancies, short intercurrency intervals, or pre- existing anemia. Thyroid function should be monitood in areaaef iodine impendency; consider 150 mcg iodine daily (often included iden prenatatatatel adpentes).

Wegetariańskie i wegańskie

This population requires careful dietary planning. Along with B12, monitor for iron, zinc, jodine, calciume, difficin D, and omega- 3 faty acid (DHA / EPA) status. A vegan multivitamin contaming B12, jodine, and virgiin D, plus an iron source if menstruating, is present. Plant- based iron absorption varies - counsel on enhancers (viin C) and mitors (phytates, tanins).

Post- Bariatric Surgery Patients

Malabsorptive procedures (Roux- en- Y gastric bypass, biliopalancreatic diversion) create lifelong difficiencies of B12, iron, calcium, accoryn D, copper, zinc, andd thiamine. Lifelong supplementation with high-dosie formulations is mandatory. Routine monitoring twice ine the first yer then annually.
