Healthy Height promotes their product for children between the ages of 3-9. However, some research shows that some older children may still benefit from this supplement when their growth plates are still open and active (before they hit puberty). Additionally, children younger than 3 may also benefit from it, but should always be advised by their pediatrician first. It’s important to keep in mind that Healthy Height is nothing more than a formula with nutritious foods, not medication, therefore, there is no harm or risk in older children consuming the shakes. In fact, the extra dose of nutrition will only serve to support their continued growth.
