Look, it`s not as simple as that. There are many stages in uptaking dietary phosphorus and Ca from digestive system to bones.

Increased concretation of those two in the bones is followed by precipitation of Ca-phosphorus salts in it. It is achived passively or by transporters on osteocytes, or both (not sure).

However, If the question is about a therapy for , let`s say, rahytis (osteomalatia) then vitamin D is frequently applied in large ammounts, or PTH (hormon) very rearly. However, problem is usualy in Calcium, not phosphorus.

ooooooooops the earlier  post was a mistake in hurry Mr Rokitansky,I place my apologies for that .

Well, as u say there r many ways in uptaking dietary P& Ca,do u think BISPHOSPONATES will help in the uptake of calcium ,fm the stomach, especially when one is undergoing treatment for endometriosis,where Gnrh anolog is the mode of treatment ?
