Vitamin D plays a crucial role in maintaining mineral balance in dialysis patients primarily due to its function in regulating calcium and phosphate metabolism. In these patients, who often experience disturbances in mineral levels due to kidney failure, adequate vitamin D is essential for promoting the absorption of calcium in the intestines and ensuring proper bone health.

Dialysis can often disrupt the balance of calcium and phosphorus, leading to conditions such as secondary hyperparathyroidism. Vitamin D helps mitigate these issues by supporting calcium levels in the blood and preventing the body from taking calcium from the bones. Additionally, it is instrumental in managing parathyroid hormone (PTH) levels, which are often elevated in patients with chronic kidney disease. Therefore, ensuring adequate vitamin D levels is critical for promoting overall mineral balance and optimizing patient outcomes in those undergoing dialysis.
