Supra said:If you take the zinc away from the rop you take out half the effects because you loose the zinc ions. Doing that you loose the benifits of zinc.
Not so. Supplemental zinc ingested orally is way different than the galvanic reaction of the ROP. The ions creating the electric current are electrons bearing no relevance to the "host" metal/element. So something like aluminum/copper would work just as well as zinc/copper.
