No calcium citrate on NHS

I was told by my gp and pharmacist today that calcium citrate is not available on the nhs.  He's going to look into it for me, but I was wondering if any of you guys use it, and if so where do you get it from - or do you just stick with the calcium carbonate, which lots of posters on the main board advise against because it is not easy to absorb. 

I use good old Boots soluble calcium. My GP said it was fine, my nut said ti was fine, my surgeon said it was fine! To heck with the band know-it-alls! It is carbonate but has vit D and citric acid to help absorption. But I am banded not RNY.

Thx Kate, I appreciate your down to earth posts, sometimes I need reminding that those who shout hardest don't necessarily know everything.  Nice having you around.
