Standard tonic water contains approximately 8.8g of carbohydrates per 100g, which is almost entirely sugar. This is comparable to the sugar content in many sodas, though the bitterness of the quinine often masks the sweetness. Always check the label as sugar content can vary significantly between brands.
Tonic water contains small amounts of quinine, which was historically used to treat muscle cramps. However, the concentration in modern tonic water is very low and generally not enough to provide medical relief. It should not be used as a substitute for medical treatment for nocturnal leg cramps.
Regular tonic water is not keto-friendly because it contains significant amounts of sugar and carbohydrates. However, diet tonic water made with non-nutritive sweeteners is zero-carb and can be included in a ketogenic diet. Always verify the ingredient list for hidden sugars.

Unopened tonic water should be stored in a cool, dry place away from direct sunlight. Once opened, it must be kept in the refrigerator with the cap tightly sealed to preserve carbonation. For the best experience, consume opened tonic water within 2 to 3 days.
Unopened tonic water has a long shelf life and is usually safe to drink past its 'best by' date, though it may lose carbonation over time. If the liquid appears cloudy or the bottle is damaged, it should be discarded. Once opened, it will eventually go flat but remains safe to consume for several days if refrigerated.
Tonic water glows a bright fluorescent blue under ultraviolet (UV) light because of the quinine it contains. Quinine is a fluorescent chemical that absorbs UV light and re-emits it as visible blue light. This is a natural property of the ingredient and does not affect its safety or flavor.
