My son of 5 not eating well en pail skin can i give him iron suplement

First get diagnosis: Pediatrician can evaluate. People who don't eat enough iron in foods, such as women who don't eat red meat, can have low iron and be anemic. Screening tests for iron deficiency are simple blood tests. If a person has low iron, the doctor will check to see if he is losing blood anywhere, as well as look for other reasons for low iron. Kids who eat enough iron in foods don't need iron supplements.
