I ubol01nderstand CA absorbability is about the same for all CA compounds. However, I have an excess of CA loss in my urine although I take a diuretic (per 24 hour urine collection test). My Vit. D level is at 38, which is normal. BMD, which had been dropping in spite of medication is now much less while on Fosamax and now on Forteo. I had been on Forteo for 10 months when the DEXA showed no improvement. Any suggestions as to what might be going on? How do I increase the absorption rate?
