In the same vein, try some Rich Chocolate Ovaltine! (My signature on the old site used to be "More Ovaltine, Please!"
Mixed with skim milk, it's probably equivalent to the nutritional benefits of Horizon's chocolate milk, but much cheaper, and adds even more vitamins and minerals. It's definitely way healthier than chocolate milk made with Hershey's syrup.
The Rich Chocolate flavor is the only one that ever appealed to me and my sweet tooth, but maybe you and your kid will like the other flavors? I chug a mason jar of it after climbing, skiing, or cycling. Mmm, so yummy! Drink it within 45 min. of your workout for the most benefit to your muscular system. It's got that nice 4:1 ratio, as well .
