Cran-blueberry Spritzer with Calcium

I love using mineral waters to help get the calcium I need.  This drink is one of my favs!

Mix 1/3 cup cranberry blueberry juice with one cup high calcium sparkling water.  I love to use a brand called Salvetat in France (253 mg/l), but others, such as Perrier (147 mg/l) are very good as well.  Just check the label.
