Any thing with ascorbic acid (vitamin C)will neutralize the iodine flavor.I believe Aqua Pure is the brand name but it comes in a two bottle package.Use the first pill to purify and the second pill to neutralize.On the bottle it says active ingredient:ascorbic acid.Now I use a Sawyer filter or chlorine dioxide.Also carry a means to boil if I need to.
