Which of the following vitamins helps in calcium absorption?

Vitamin D plays a crucial role in the body’s ability to absorb calcium, which is essential for maintaining healthy bones and teeth. The primary function of vitamin D is to enhance intestinal absorption of calcium and phosphorus from the diet. When the skin is exposed to sunlight, it produces vitamin D, which can also be obtained through certain foods and supplements.

Without adequate levels of vitamin D, the body struggles to absorb the calcium consumed through dietary sources, leading to potentially compromised bone health. This connection underscores why vitamin D is often referred to as the "sunshine vitamin," emphasizing its importance in bone health and its vital role in regulating calcium and phosphorus balance in the body.
