The calcium in supplements is found in combination with another substance, typically carbonate or citrate. Each has benefits and downsides. Calcium carbonate supplements tends to be the best value, because they contain the highest amount of elemental calcium (about 40% by weight). Because calcium carbonate requires stomach acid for absorption, it's best to take this product with food. Most people tolerate calcium carbonate well, but some people complain of mild constipation or feeling bloated. Some well-known calcium carbonate products include Caltrate, Viactiv Calcium Chews, Os-Cal, and Tums.
Calcium citrate supplements are absorbed more easily than calcium carbonate. They can be taken on an empty stomach and are more readily absorbed by people who take acid-reducing heartburn medications. But because calcium citrate is only 21% calcium, you may need to take more tablets to get your daily requirement. Calcium citrate products include Citracal and GNC Calcimate Plus 800.

The more you can exercise, the better you will feel, and it will be better for your body. We just have to be careful how we exercise, and don't do any exercise that hurts when you do it. Don't over do, start slowly and build up. That old slogan "no pain no gain" is for young fools. We vintage ladies with osteoporosis have special issues that need to be treated with care. So get off that couch and go for a short walk, and it's always safer and more fun if you go with someone. And remember to always wear quality, well fitting, good support shoes when you exercise.

Thank you so much for the u tube!! That helps a whole lot. I guess silver sneakers and yoga are good for me. I was questioning it, Now I will go back there!
