Why might vitamin D deficiency contribute to hyperlipidemia?

• A. Vitamin D is needed for lipid cell membranes formation
• B. Vitamin D directly lowers cholesterol
• C. Vitamin D is not involved in lipid metabolism
• D. Vitamin D increases lipid oxidation

Answer: (A)

Vitamin D status influences how lipids are handled in the body. The vitamin D receptor regulates genes involved in lipid metabolism, including those tied to cholesterol synthesis, lipoprotein production and clearance, and possibly membrane lipid composition. When vitamin D is deficient, these regulatory pathways can be less active, leading to altered lipid production or clearance and a tendency toward higher circulating lipids, i.e., hyperlipidemia. The concept captured by the option is that vitamin D supports lipid-related processes essential for membrane and lipoprotein structure, so insufficient vitamin D can disrupt lipid homeostasis. It’s not simply that vitamin D directly lowers cholesterol, nor is its role limited to not being involved or to increasing lipid oxidation, so the stated reason aligns best with vitamin D’s influence on lipid metabolism and membrane-related lipid handling.
