THE CALCIUM MASTER
A-21 parathyroid peptide bioregulator
Bonothyrk is derived from the parathyroid glands and helps restore optimal calcium regulation in your body. It works by supporting your parathyroid's ability to produce PTH (parathyroid hormone), which controls calcium levels, bone density, and neuromuscular function. It's particularly useful for preventing osteoporosis and muscle cramps.
