I'm new to all of this with a recent diagnosis of Osteopenia and Osteoporosis. I'm trying to gather as much information as possible to make an educated decision about what route to take in order to deal with this. I'm so confused about Calcium--what kind to take, how much to take, when to take it, whether or not it actually does any good. Everything I have read talks about the absorption. It seems like no matter how much you take hardly any of it gets absorbed. Can anyone offer some help?
