I have read nearly all of your profiles, and see that some say they take calcium, or perhaps another will mention magnesium, or just vitamin D3.
There are a few different types of Calcium, but it's the Citrate we need to protect our bones. The magnesium is great for our muscles, and so very many of us are D3 deficient.
Here is a link about Calcium citrate, and I will also include one that talks about how these vitamins need to be balanced with the others to effective and provide us with the best protection against bone loss, and ease muscle pain and spasms.
I know that there are a few members who have a vast knowledge of vitamins, that I have learned so much from. Please share with us the vitamins that you take, especially to prevent Osteoperosis.

This last link mentions algae cal, our member Allergic who is a nurse was telling me of one of her friends reversing Osteoperosis by taking this for a year! I am considering trying it, as I was recently diagnosed with Osteopenia.
My Rheum told me 1200 mg of Cal citrate daily, while my Chiropractor told me I could take 1800 mg daily! Always check with your physician before adding any supplements to your meds!
I am interested in any information you can include. Thanks, SK
