Had some issues where I was losing bone mass on my ankles and also had an issue with bone loss on my mandible. A friend recommended I take this, its been a year and I have slowly recuperated the bone loss in my mandible. I have also take calcium, magnesium and zinc supplements to assist with it as im unable to have dairy. The product was shipped promptly and I received it right away without any issues, I purchased from Best Deals International, same price as amazon, but I rather help a small business
