An 8 oz (240 ml) serving of Clamato juice typically contains about 70 calories, 700 mg of sodium, 10 grams of sugar, and 2 grams of protein. The high sodium comes mostly from added salt and clam broth, while sugar is added to balance the acidity of the tomatoes and spices.

Low sodium Clamato juice options exist, offering significantly less salt while keeping the characteristic flavor. Alternatively, homemade versions can reduce both sodium and sugar by controlling added salt and sweeteners.
