The collagen matrix is then hardened by calcification. The process of bone remodeling is carefully regulated. Hormones produced by the parathyroid and thyroid glands tell the osteoclasts to break down bone when calcium is needed in the bloodstream. When calcium phosphate in food is absorbed, it affects the levels of calcium in the blood. Vitamin D helps your body absorb calcium so that it can be used in bone building.
Bone formation exceeds bone loss throughout childhood, adolescence, and early adulthood.
During these developmental stages, bones continue to grow until they reach their peak mass or density. After the age of 40, the tables are turned, and bone loss exceeds bone formation. Although a net loss of bone is inevitable, preventative measures involving preparation and discipline can be introduced to help minimize the loss. When women enter menopause, they stop producing estrogen, and the rate of bone loss increases. Because women have smaller skeletons than their male counterparts, they have less bone mass from the outset, contributing further to the higher incidence of osteoporosis in women than in men.
