    Calcitonin is produced in the parafollicular cells of the thyroid. It controls the calcium content of the blood by increasing bone formation by osteoblasts and inhibiting bone breakdown by osteoclasts. Calcitonin reduces blood calcium levels by putting calcium back into the bone. Calcitonin works the opposite way that the parathyroid hormone works.
