What vitamin is important to take with calcium to maximize absorption?

The correct answer is Vitamin D because it plays a crucial role in enhancing the absorption of calcium in the intestines. Calcium is not easily absorbed by the body on its own; it requires the presence of Vitamin D to facilitate this process. Vitamin D works by increasing the efficiency with which the intestines absorb calcium from the diet, helping to maintain adequate calcium levels in the bloodstream and supporting bone health. This synergistic relationship is particularly important for individuals who may be at risk of deficiencies in either calcium or Vitamin D. Therefore, ensuring adequate levels of Vitamin D is essential for maximizing the benefits of calcium intake.
