We are not receiving proper levels of Vitamin D from milk. By the time the farmers are done boiling the milk, all the nutrients are gone. It's funny I was just going to suggest Chew-4-Health as a supplement and I saw the add to the right. All three of my children were recommended this by our pediatrician. We are so impressed by their great health and mental clarity through out the day in school! We need to be giving our children natural chewable supplements to keep them healthy!!!
