Parathyroid Hormone (PTH)

Meaning

Parathyroid Hormone (PTH) is a vital polypeptide hormone secreted by the parathyroid glands, acting as the primary endocrine regulator of calcium and phosphate homeostasis in the extracellular fluid. Its physiological role is to elevate circulating calcium levels when they fall below the homeostatic set point, protecting against hypocalcemia. PTH achieves this by acting on the bone, kidney, and indirectly on the small intestine, making it an essential component of skeletal and mineral metabolism in the context of hormonal health.

A distinct, aged, white organic form with a precisely rounded end and surface fissures dominates, suggesting the intricate pathways of the endocrine system. The texture hints at cellular aging, emphasizing the need for advanced peptide protocols and hormone optimization for metabolic health and bone mineral density support.
