I know you don’t like giving vitamins or other supplements to children just in case, what about if their pediatrician has prescribed them? For example what about Vitamin D or iron?

I am not against the use of vitamins and minerals if there is laboratory evidence they are required, such as is commonly the case when the pediatrician prescribes vitamin D or supplemental iron. I am very much against the broad application of various supplements that are being used “just in case” or because someone else’s child seemed to do better on them.
