Do you want to protect yourself and your family from sniffles and colds this winter? According to the Academy of Nutrition and Dietetics one of the best things you can do is consume more Vitamin C. In addition to helping the body repair itself, Vitamin C is also good for absorbing excess iron. For natural sources, look for fresh red bell peppers, broccoli, and tomatoes. No fresh veggies around? Take a high quality supplement instead.
