<<Disclaimer: Verify this information before applying it to your situation.>> I have taken OSCal calcium for years and have never had problems. When I began taking them I checked and was told they were gluten free. I am now taking Freeda calcium. I changed because I can no longer have sugar and the OsCal had corn syrup in them.
