Question: 1 / 495

Which vitamin is essential for calcium absorption in the body?

Vitamin A

Vitamin B12

Vitamin C

Vitamin D

Vitamin D is crucial for calcium absorption in the body. It plays a significant role in maintaining bone health and regulating calcium levels in the bloodstream. When exposed to sunlight, the skin synthesizes vitamin D, which then promotes the intestinal absorption of calcium. Without adequate vitamin D, the body struggles to absorb calcium efficiently, which can lead to bone deficiencies such as osteomalacia in adults and rickets in children.

The importance of vitamin D extends beyond just absorption; it also helps to maintain adequate levels of calcium and phosphate in the blood, which are necessary for healthy bone formation. Therefore, ensuring sufficient vitamin D intake is essential for optimal calcium utilization and overall skeletal health.
