What is club soda, and how is it different from carbonated water?
Club soda is a carbonated water sold for drinking and mixing. USDA lists it with 0 calories, 0 g sugar and 21 mg sodium per 100 g, about 75 mg in a 12 oz can (our calculation), so it is the one that carries some salt. We found no official legal definition that separates club soda, seltzer and sparkling water.

What is club soda?
USDA’s food database lists club soda under carbonated beverages. Per 100 g it has 0 calories, 0 g sugar, 0 mg caffeine, 5 mg calcium, 2 mg potassium and 21 mg sodium. The sodium is what a plain seltzer would normally lack, so club soda is often described as a salted fizzy water. USDA does not say which salts are used.
Is club soda the same as carbonated water?
In everyday use, club soda is one kind of carbonated water: water with carbon dioxide, and here a little sodium. We found no FDA or USDA page that defines club soda, seltzer, soda water and sparkling water as separate legal categories. FDA’s bottled water rule (21 CFR 165.110) says bottled water does not include products labeled seltzer water, soda water, sparkling water or tonic water. It does not mention club soda. The only FDA-defined type is sparkling bottled water, which keeps the natural carbon dioxide of its source.
What are the ingredients in club soda?
We found no official ingredient list for the whole category. Brands differ, so read the label. The salts named in many articles, such as potassium sulfate or sodium citrate, could not be confirmed from an official source.
