The chewable calcium citrate adult I found on iHerb only one and it was not calcium in its pure form, and a small set of vitamins and minerals - with the addition of vitamins D and K, magnesium and zinc for better absorption of calcium, as well as extracts of raspberry and cranberry to improve digestion. In general, a very good set, only for sunny days in it too much of vitamin D, so it is best to take it in the winter and in the offseason. The complex consists of a large circular solid tablet with a pronounced cocoa taste. As for me, it is edible and even delicious, you can eat a bit of sugar with their tea as candy.
