Hi Anna, welcome... Here's a link to the manufacturers of Fosteum explaining who can and can not take it. It will also answer many other questions as well.
If you are allergic to any of Fosteum's ingredients, you shouldn't take it. Fosteum has Genestein in it, which is isolated from soy, so check with your Dr. to see if this would be contraindicated.
Good luck and let us know what you find out.
