It is not likely that a calcium supplement reversed osteoporosis. Advacal is like other supplements in that it has calcium, K2, D3, and some minerals. There's nothing special about it. It helps to make sure that you're getting those things, but it is not a cure.

Osteoporosis is usually not an issue of insufficient calcium. The bone remodeling process in the body gets out of balance. There can be a number of causes - and something the cause its unknown. I wish it were as easy as buying a pill on Amazon. 🙂
