Which vitamin is primarily associated with bone health?

  1. Vitamin A

  2. Vitamin C

  3. Vitamin D

  4. Vitamin E

The correct answer is: Vitamin D

Vitamin D plays a crucial role in maintaining bone health because it is essential for the absorption of calcium and phosphorus, both of which are vital minerals for bone formation and density. Without adequate vitamin D, the body struggles to absorb sufficient calcium from the diet, which can lead to weakened bones and conditions such as osteomalacia in adults and rickets in children. The activation of vitamin D occurs primarily in the skin through sunlight exposure and also through dietary intake, emphasizing its importance in both prevention and treatment of bone-related diseases. In contrast, vitamins A, C, and E, while beneficial to overall health, do not have the same direct influence on bone mineralization and strength as vitamin D does.
