Healthy infants can take Icocin from about two weeks of age and need to take it at least until they are two years old, and it is recommended to take it then for another winter. Infants need a lot of vitamin D and vitamin A during their growth and development, and the main ingredients of Iconocin are vitamin D and vitamin A, which can promote the absorption of calcium. If the infant is sick within two years of age, there is usually no need to stop taking it. It is recommended that the health and nutritional status be evaluated every six months while the baby is taking it, and that the results be used to determine whether the amount of each dose should be changed. Breastfed babies should eat more vegetables and calcium-rich foods to promote the absorption of calcium and to maximize the effects of Iconocin.
