Your bones are in a constant state of renewal — new bone is made, and old bone is broken down. HGH is a prime mover in this process. As we age, HGH levels drop, and old is no longer replaced as well as it was when we were younger, and bone mass is lost faster than it's created. This leads to the weakening of bones typical of osteoporosis. Osteoporosis affects men and women of all races. But white and Asian women — especially older women who are past menopause — are at the highest risk of developing osteoporosis.
