This product has a risk that it could melt during shipping by ground services due to the warm weather, especially during the summer months from May through August. We would suggest you to choose any expedited or express carrier service available during those summer months, however, this still does not guarantee that it will not melt. Kirkland Signature Complete Children’s Multivitamins Gummies are a perfectly balanced formulation of key vitamins and minerals to support the healthy growth and development of children. Your child will love the delicious orange, cherry and green apple flavors and you can feel good knowing we use only natural fruit flavors. Vitamins A, C, and D and the mineral zinc are all included in this formula to support immune health. Vitamin C is important for the normal production and functioning of white blood cells. Vitamin D also appears to assist with the regulation of these cells. White blood cells are an important part of the immune system that are found throughout the body in the blood and lymph. Vitamin A is involved in the regulation of important immune response elements, and contributes to the body’s physical barrier of defense by supporting the integrity of the respiratory, GI and urinary tracts. The mineral zinc is also included because of its important role in immune function. Children’s Complete Multivitamin Gummies offer the immune support to keep your child at his/her healthy best all year long. UPC: 000000897980 Weight: 2.63 lbs RKU: COS897980
