Not all forage has too much iron, though it is pretty normal in the UK. To counter that you need copper, and then zinc in a 3 to 1 ratio to balance the copper. You do not need a full spectrum balancer. Mud fever can generally be resolved with copper and zinc, which strengthens the skin, ime.
In addition, most full spectrum balancers contain added iron, too little copper and zinc, and often other fillers that horses don't need.
If the OP needs to balance out iron and not buy copper and zinc alone, then she should buy one of the very, very few balancers that have enough copper and zinc.
IMO if she doesn't have foot/coat quality issues then it is difficult to see why the vet wants her to use any kind of balancer, especially without knowing what is supposed to be being "balanced".

I suspect the vet might think the horse the would benefit from the protein as well as the antioxidants most balancers contain .
