Are there any benefits in drinking club soda?

Well kind of.

It's essentially the same thing as water, except it contains CO2. Co2 does hurt humans in this form so, club soda is basically just drinking water-very healthy :) !

Also, if this is in a substitute for a soda, its even more healthy! You are not injesting all of the harmful chemicals to your teeth (Comparable to batttery acid) and toxins to your body (Aspartame-a carcinogen)

Final Answer- Club soda is beneficial by hydrating yourself and mabey not drinking as much soda.

Hope this helps!!
