<<Disclaimer: Verify this information before applying it to your situation.>> Recieved 17 responses and all but 2 said that it was safe. One of the 2 said that it had made them ill. One said that they had been taking it for 2 years with no problems. The others have either taken it or were taking it and it was ok. The company said that it was "safe" with a doctor prescribing it and to follow what he/she said. I have been taking it and have no problem. Thank you for all that answered my query. Kate/Illinois
