I've read too much calcium (Hypercalcemia) encourages Calcitonin secretion, which is linked in various studies to inhibiting GH. Is it possible too much calcium would stunt growth?

but calcitonin would decrease calcium levels so you wouldn't have continual high calcitonin levels to inhibit GH significantly...

AFAIK, the source of calcium is important role in this too. Milk calcium has this affect, but not so much calcium from green leafy vegetables. I'm not sure why, perhaps something to do with the absorption rates.

 

I'll try and find a source for this.
