--- name: endo-vitd-supplementation-over75 description: Suggests empiric vitamin D supplementation to lower mortality risk in adults aged 75 years and older. Triggered by clinician questions such as “Should I prescribe vitamin D to this elderly patient?” or “Is vitamin D supplementation indicated for patients over 75?” --- # Vitamin D supplementation for adults over 75 ## STEP 1 — Gather Information Confirm patient age ≥75 years, absence of established indications for vitamin D treatment or 25(OH)D testing (e.g., no malabsorption, renal osteodystrophy, granulomatous disease, hypercalcemia, or current vitamin D deficiency therapy), and assess current vitamin D supplement use; determine eligibility for empiric supplementation. ## STEP 2 — Rule In / Rule Out If the patient is ≥75 years and generally healthy without contraindications, proceed; otherwise, do not recommend empiric vitamin D supplementation for mortality prevention and consider alternative indications or testing. ## STEP 3 — Classify or Stratify Classify preferred dosing regimen: daily lower-dose vitamin D (preferred) versus nondaily higher-dose regimens; choose daily lower-dose vitamin D as the preferred regimen. ## STEP 4 — Decide Prescribe empiric vitamin D supplementation via daily lower-dose (e.g., 800–1000 IU vitamin D3 per day) and advise against routine 25(OH)D testing. ## Clinical Guardrails / Mimics / Pitfalls Do not use in patients with conditions that alter vitamin D metabolism (malabsorption, renal failure, granulomatous diseases, hypercalcemia); avoid high bolus dosing; do not rely on 25(OH)D levels to guide dosing; do not extrapolate to those with established indications for vitamin D treatment; supplementation is inexpensive and feasible but should not replace dietary intake when adequate. ## Concrete Clinical Example A 78‑year‑old woman without malabsorption, renal disease, or hypercalcemia asks whether she should take vitamin D to lower her mortality risk; she is not currently taking a supplement. Recommend initiating daily vitamin D3 800–1000 IU and counsel against routine 25(OH)D testing. **Source:** Vitamin D for the Prevention of Disease: An Endocrine Society Clinical Practice Guideline, Endocrine Society, 2024, DOI:10.1210/clinem/dgae290
