What is the primary function of Vitamin D?

Question

BlackTom AI · Accepted Answer

When considering the primary function of Vitamin D, it helps to recall its key role in mineral metabolism and bone health.
Option A: 'Promoting absorption of iron in the body.' While iron absorption is important for hematologic function, Vitamin D is not primarily involved in increasing iron absorption; this makes A incorrect.
Option B: 'Suppressing the immune system response.' Vitamin D actually contributes to immune modulation and support rather than simply suppressing immune responses; its primary function is not immune suppression, so B is not accurate as a description of its main role.
Option C: 'Increasing blood sugar levels.' Vitamin D has no direct primary role in increasing blood glucose; this statement misstates its metabolic function, rendering C incorrect.
Option D: 'Promoting absorption of calcium and phosphorus.' This aligns with well-established physiology: Vitamin D enhances intestinal absorption of calcium and phosphate (phosphorus) to support bone mineralization and overall skeletal health, making D the correct description of its primary function.
