What are the nutrition facts for tonic water?

Tonic water is carbonated water with sweetener, citric acid and quinine for its bitter taste. US brand labels list about 130 calories per 12 fl oz for regular tonic, and a generic data entry gives about 124. Sugar is roughly 30 g or more per 12 fl oz. It has no fat. Values vary by brand, so check the label.

Type Approx. per 12 fl oz
Regular tonic About 110 to 130 calories; about 30 g sugar or more
Zero-sugar tonic About 0 calories, with artificial sweetener

Is tonic water low in calories?

No. Regular tonic has about as much sugar as many sodas, so it is not a diet mixer. For fewer calories, choose a zero-sugar or light tonic.

What is quinine in tonic water?

Quinine is a bitter compound from cinchona bark, once used to treat malaria. In the US, the FDA regulation allows quinine in carbonated beverages at up to 83 parts per million, and the label must state that quinine is present. That is a flavoring limit, far below the doses used in quinine medicines. Tonic water is not a treatment for malaria or leg cramps, and the FDA has warned against using quinine medicines for leg cramps. Ask a doctor if you are pregnant, take medication or have had a reaction to quinine.

How to use tonic water

  • Mixer for gin or vodka; remember the sugar adds up.
  • Mix half tonic, half soda water to cut sugar.
  • Choose zero-sugar if you are watching calories.

What else to check on the label

  • Sweetener: sugar, corn syrup or a zero-calorie sweetener.
  • Serving size: cans and bottles differ.
  • Vitamin and mineral claims: tonic is not a significant source of vitamins.
