What is Calcitonin (Salmon)?

Calcitonin is a 32-amino acid peptide hormone naturally produced by the thyroid gland's parafollicular C-cells. Salmon calcitonin is 40-50 times more potent than human calcitonin and is FDA-approved for treatment of postmenopausal osteoporosis and Paget's disease of bone. It works by directly inhibiting osteoclast activity, reducing bone resorption.

How It Works

Calcitonin tells the cells that break down bone (osteoclasts) to stop working. This slows bone loss and can help relieve pain from bone conditions like osteoporosis and fractures.

Common Side Effects

Nasal irritation (nasal spray)NauseaFlushingInjection site reactions

Cautions

  • FDA warning about potential cancer risk with long-term use
  • Not first-line therapy for osteoporosis anymore
  • Antibody formation may reduce efficacy over time

What We Don't Know

Long-term cancer risk concerns have limited its use, though the absolute risk increase appears small.
