Thanks! I'm a newbie, as I was only diagnosed 2 weeks ago with severe osteoporosis and I'm scrambling to get up to speed. I immediately bought 2 large bottles of calcium, only to later learn that due to my high coronary calcium scores, I should not use them! So I'm thrilled to learn about this water. Getting 260mg of calcium from 1 bottle of water daily makes it alot easier for me to manage!
