Many findings has been suggested that inadequate dietary boron may one factor than enhances the susceptibility of bone loss and osteoporosis because of the mineral’s possible effect on calcium metabolism.
Feeding low boron to humans with <0.3 mg/day altered the metabolism of macrominerals, electrolytes and nitrogen as well as oxidative metabolism and produces changes in erythropoiesis and hematopoiesis.
