Just FYI you can't overdose on vitamins or minerals by getting your 100 percent RDA through the shakes and bars, plus taking a general multivitamin (which usually includes potassium). It's the same as eating normal food (assuming you were getting 100%) then taking a multi, which a lot of people do. You don't absorb all the vitamins and minerals from the shakes and bars just because you are ingesting them. If any doubt ask a doctor, everyone is different. It makes sense that adding salt helps because almost all salt is enriched with iodine.
