Document Summary
Store calcium in the bone, bone acts as reservoir. Blood levels of calcium are maintained in any lost bone. When ca high intake, build bone, when low intake, dissolve bone. Necessary for calcium absorption (much have d to absorb calcium) Osteomalacia (adults) weakens bones, not enough mineral in them. Blood levels are going to be too high, deposited in places you don"t want it to (soft tissue, kidneys, etc. ) Osteocalcin (low k intakes- higher risk of bone fractures), also more prone to bleeding. Not important for bone strength as much as a place to store it. Jumping (even 40 jumps a week can increase bone density), Jumping (even 40 jumps a week can increase bone density), plyometrics. Low body fat can cause low estrogen levels. Elderly people get shorter as they lose bone density. Lower sun exposure, less efficient synthesis, less efficient activation of precursor, mucosa- less responsive, lower ca absorption.
