Tonic water is a popular beverage known for its distinct bitter taste and effervescence. It is commonly used as a mixer in cocktails but can also be enjoyed on its own.

Calorie Content

Tonic water is relatively low in calories compared to other carbonated beverages. On average, an 8-ounce serving of tonic water contains approximately 90 calories. However, it’s important to note that the calorie content may vary among different brands and flavors.

Carbohydrate Content

Tonic water contains carbohydrates in the form of added sugars. The sugar content can range from 20 to 30 grams per serving, contributing to the overall calorie count. It’s worth noting that excessive sugar consumption can have adverse effects on health, so moderation is key.


Quinine is a key component of tonic water that gives it its distinctive bitter taste. It is derived from the bark of the cinchona tree and has historically been used to treat malaria. In modern tonic water, the quinine content is significantly lower and primarily included for flavor.

Sodium Content

Tonic water typically contains a small amount of sodium. A single serving can have around 5 to 10 milligrams of sodium. While this amount is relatively low, individuals following a low-sodium diet should be mindful of their tonic water intake and consider lower-sodium alternatives if necessary.


The effervescence of tonic water is a result of carbonation. Carbonated beverages can cause bloating and discomfort in some individuals. If you experience such symptoms, opting for still tonic water or reducing carbonated beverage intake may be beneficial.

Quenching Thirst

While tonic water can be refreshing, it’s important to note that it may not be as effective at quenching thirst as plain water. The presence of sugars and other additives can leave you wanting more, so it’s essential to balance tonic water consumption with adequate hydration from water.


Tonic water may contain some antioxidants derived from its ingredients. For example, citrus-flavored tonic waters may provide a small amount of vitamin C, which is known for its antioxidant properties. However, the overall antioxidant content in tonic water is relatively low compared to fruits and vegetables.
