Not exactly - an iron supplement will give his body the building block he needs to make more RBCs, but there is no food or supplement that can stimulate red blood cell production. A medication called erythropoietin can stimulate RBC increase - this is an injection that would be given at your vet. It has to be given three times a week initially and then can be modified after that. It usually takes about a month to see the results we want, so at this point I would wait to start it with your boy until you decide if we are going to pursue further treatment/diagnostics with him.
