Is there any sugar in effervescent k-lytte?

Yes, A Small Amount: Every manufacturer of potassium supplements may vary in the amount and type of sugars, but there will be a small amount. (even in the tablets that are swallowed whole.) most medications that have flavorings will have added sugars to make the flavoring taste good. Potassium is very bitter tasting and the effervescent forms require flavor and sugar to cover the taste.
