Has anyone (that is not a seller of a product) tried any of the nutritional supplements that are available for kids? I was approached by a representative that sells Reliv products when she saw my son wearing his transplant mask. She suggested the children's product for my 8yr old son. He has had transplants to cure his not so common Leukemia. He is one year out from his last transplant and so far so good. But with all the treatments he has had, it has compromised some of his nutritional needs, such as calcium, etc.
