Vitamin D

What is Vitamin D for?

Vitamin D (also known as Cholecalciferol for Vitamin D3) is required by the body for absorption of calcium and in maintaining bone structure. It is effective for preventing osteoporosis and fractures when given together with calcium.

Vitamin D is also used to treat low calcium levels in the blood (hypocalcemia) and poor parathyroid function in chronic kidney disease (CKD). The parathyroid glands control the body's calcium levels.

Vitamin D in its active form like Calcitriol, Alfacalcidol or Paricalcitol are effective for the treatment of poor parathyroid function in CKD.
