<<Disclaimer: Verify this information before applying it to your situation.>> So many people here have asked for a GF calcium supplement that I thought I'd offer this suggestion. Since calcium citrate is much easier for people to assimilate than calcium carbonate, then it might be a good idea to try Citracal: according to Guide Through the Medicine Cabinet by Stokes Pharmacy, Citracal or Citracal + D or Citracal Liquitab are all GF and dairy free. It might be a good idea to try this, even if it is advertised by Paul Harvey :) -vance Charles Darwin was a naturalist who wrote the organ of the species.
