It'll end up as much as a twentieth of a teaspoon of salt per bottle, depending on the soft drink. This is not a huge dose all by itself but you don't register it as salt: it sneaks in as part of other ingredients, rather than being added by the spoonful in raw form (that said, 'natural flavorings' can cover a lot, so it CAN be just added as part of the recipe.) Leave it out and your flavor balance will be more along 'New Coke' lines.
