What are health benefits of calcium?

You need a lot of calcium: 1,000 mg per day for women and men up to age 50 and 1,200 mg after that. Calcium helps preserve and build bone and regulates heart rate, muscle function, and blood pressure. It's also linked to prevention of several types of cancer and type 2 diabetes.

You can get it all through your diet, but you have to work at it. There are a variety of calcium supplements; both calcium carbonate (such as Tums) and calcium citrate (such as Citracal) are well absorbed when taken with a meal. These and other brands have versions that include vitamin D, good choices if you want more than the 400 IU in most multivitamins.
