calcium, sodium, magnesium

This is very cibai. So it is good to figure it out :

• 1. Bone is a reservoir for Ca, Na, Mg, in descending order of mass
• 2. If one of these minerals is deficient in serum, the entire bone structure gets resorbed, and the other excess minerals are dumped into urine
• 
  
• 3. Finally the same minerals are reabsorbed by the kidney using a common mechanism, so dumping any of one, dumps more of the others too

Practical conclusion : Ca, Na, Mg need to be consumed together
