From the Manufacturer:
Kid's Stuff provides a full range of vitamins and minerals for children. Children get a full day’s worth of many vitamins and minerals from just one chewable tablet. Many children need iron to help prevent anemia and Kid's Stuff provides a significant portion of the daily needs. Adolescent girls who are starting their periods also often need additional iron. Calcium is a necessity for strong teeth and bones but many children do not drink milk, one of the primary sources of calcium for children. Kid's stuff will help meet some of that daily need by supplementing the diet.
