"optimally functioning digestive system is very important" could be a direct response from my sister who was a Registered Dietician for 30+ years (Michigan State and internship at Mass General). Because of her I'm on Tymlos as her advice was that anything that would disrupt or hurt the digestive system would prevent healing.
It is now on the record that there two of us with osteoporosis who believe that the digestive system is important!
