In my opinion this is the healthiest form of calcium you can buy. I'm 68 and have been diagnosed with osteoporosis for many years which resulted in frequent fractures and pain and discomfort in my bones. After two years of using this product I now have been diagnosed with osteopenia which is a milder form of osteoporosis. So my bone density has increased without the use of harmful medications. Because this is food grade calcium the body metabolizes it effectively, efficiently and safely.
