Wellkid Immune Chewable contains specific nutrients such as zinc, which contributes to normalimmune system function. It also contains supporting botanical ingredients including citrus bioflavonoids, natural carotenoids and vegetarian flaxseed oil.Calcium is an essential mineral, also needed for normal growth and development of bone in children. However, it has not been included in the Wellkid Immune Chewable formula, as it is not possible to include the right amount in one tablet. For mothers particularly concerned about the normal bone health of their children we recommend Wellkid Calcium Liquid, which can be taken alongside Wellkid Immune Chewable and contains calcium and vitamin D.Calcium is an essential mineral, also needed for normal growth and development of bone in children.
