Phosphorus is the sixth(*) most important component of our bodies, mainly in the form of phosphates. Phosphates are key components of DNA, cell structures and energy transmission in cells, as well as bones and teeth, and are involved in many biological processes. They are essential to the health of all living creatures.
As our bodies regularly excrete phosphates through the kidneys, it is vital that we constantly replenish our supplies.
To ensure good health, the minimum RDA is 700 mg for adults, 800 mg for pregnant women and 1,250 mg for teenagers.
Phosphorus and calcium intake need to be balanced, as high doses of either may prevent assimilation of the other. This is why some women who are given calcium supplements for osteoporosis also need to take phosphate supplements.
(*)Hydrogen 63%; oxygen 25% (including body water content), carbon 9.5%; nitrogen 1.4%; calcium 0.33%; phosphorus 0.22% .
