Ben, the iodine you need, and that too much of can affect the thyroid (but that takes a whopping huge dose) is the ionic form, iodide.  Though Potable Aqua tablets include potassium iodide, I understand that is to make the iodine (molecular form, nonionic) more readily soluble.  It is the molecular form that is the effective disinfectant.  In fact, some backpackers, back in the day, used to just put a lump of molecular iodine in the water bottle.  It is barely soluble, and will dissolve over time to an equilibrium point.  Once the water is refilled, it begins to dissolve again.  Just make sure not to swallow the lump!

So far as choice of beverages, mine won't be coming from a soft drink bottle or as bottled water, at least on a usual basis.  I'll take the camper tank water over either.
