About 6 mo. ago my retired gelding was diagnosed as anemic. I began
using Red Cell. Shortly after I acquired a 9 yr old mare which I have
started in endurance. Figuring red blood cells are an asset to an
endurance horse I put her on Red Cell also. Now that the gelding's
blood is back to normal, I am wondering if I should continue the
endurance mare on Red Cell. Is it possible to o.d. on iron?
