The human requirement for boron is estimated to be between 0.3 and 1 milligram per day - an amount easily consumed though a normal diet.
Boron is found in many tissues; however, bone contains the most. Boron has been shown to replace iron in some of its functions, particularly in the healing of wounds.
Boron appears to either directly or indirectly affect the metabolism of calcium in bone and influence the composition and strength of bone.
In situations where the body receives an adequate supply of calcium but has deficient magnesium resources, boron seems to actively substitute for magnesium during the process of bone formation.
Boron needs are increased during a vitamin D deficiency.
Boron has the ability to reduce the urinary excretion of calcium and magnesium. It preserve calcium in the body, while decreasing urinary losses of calcium, through its actions on the kidneys.
