Calcitonin

Calcitonin is a hormone produced by the thyroid gland that helps regulate calcium levels in the body. It acts primarily by inhibiting the activity of osteoclasts, the cells that break down bone, which reduces the release of calcium into the bloodstream. This process helps lower high blood calcium levels. Calcitonin is also involved in bone health and may be used as a treatment for conditions like osteoporosis, where bone density decreases. Overall, it plays a key role in maintaining calcium balance and supporting strong bones.
