They make some pretty tasty calcium chews. All sorts of different flavors like chocolate and vanilla. They come in a purple container, but I can't remember the name, you can find it in any store.
On iherb.com, I was searching for a vit. D supplement, they make chewables in sour orange and lemon flavor. Reviewers say it tastes like a lemon drop. I'm gonna have to try some myself. Mmmmm!
