Both are totally different. Bioactive vitamin D or calcitriol is a steroid hormone that has long been known for its important role in regulating body levels of calcium and phosphorus, and in mineralization of bone. While HPT occurs when one or more malfunctioning parathyroid glands produce an excess amount of PTH and raise the blood calcium level, calcitonin does not play a major role in HPT.
