Hi winston, i donate regularly, over 60 units, and have never been ask that. As long as your not taking any of the drugs on the can't donate list or other reasons you can donate. You could call the Red Cross and ask to be sure, but if they turned away people with osteo they would be losing a lot of good donors. take care...phyllis
