Hi Molly, Strontium Citrate is not available here in Canada. Until they get a patent, and decide on fillers like (sulfites (in all drugs here in Canada), corn starch, lactose etc. - all things I am allergic too - only guessing on fillers). Will check it out though, when and if there is ever a patent for the drug here in Canada.

PS: Some of the foods with the natural Strontium, I am still able to eat (at least today - tomorrow don't know). Molasses is off my list of foods.
