i went to my natural doctor today and she thought my supplements that i was taking was a good start but wants me to try ostinol. ostinol is put oou by zycal bioceuticals and has been CLINICALLY PROVEN to stimulate mesnchymal stem cells that grow bone(thats osteoblasts). its a bone derived protein compleX which containsBMP, BONE MORPHOGENETIC PROTEINS. it is supposed to naturally activate bone and cartilage growth. im now taking 2 tablets a day. she feels strongly that it will reverse my osteoporosis. but, im also 42 yrs old and i have no medical problems or diseases to get under control. ostinol is supposed to repair the inner bone, unlike biophosphinates she explained work on the outer layer of the bone and just causes bone to be more brittle. i just wantd to share this with everyone in case it might help someone else also.the webite is www.zycalbio.com. my doctor also explained that this BMP was originally used by orthopedic surgeons on their patients to ensure that they grew good quality bone and the fracture healed well.
