Several people have mentioned Tropicana with Calcium, so I pulled our container out of the fridge. This is what my son drinks every morning with breakfast and he has an anaphylactic allergic to cow's milk and its proteins. The product is called: Tropicana Pure Premium Calcium and extra Vitamin C. The ingredients: Orange Juice, FruitCal (Calcium Hydroxide, Malic Acid, Citric Acid) and Ascorbic Acid. The number to call for more information: 800-237-7799. My son has had no reaction to it...but it's always better to check with the manufacturer to be sure! Rose
