Tonic water is a carbonated soft drink flavoured with quinine, which gives it a distinctive bitter taste. Standard tonic water contains added sugar (around 7-8g per 100ml) and around 83mg quinine per litre. Quinine was historically used to treat malaria; at tonic water concentrations it has no therapeutic effect. Slimline tonic water uses sweeteners instead of sugar. It provides negligible nutrition beyond carbohydrate.
Choose slimline tonic water to eliminate the sugar burden when making gin and tonic; it contains the same quinine flavour without the 70+ kcal per can from sugar. Those on the antimalarial quinine drug should discuss tonic water with their doctor.

* % Daily Value is the proportion of an adult
EU Nutrient Reference Value (NRV) supplied by 100g of this food.
NRVs are the labelling standard — the same basis as the “%RI” figures printed on
food packaging — so these percentages are directly comparable with a shop label.
They are a single adult figure and do not vary by age or sex, which is why they
sometimes differ from UK dietary reference values: the NRV for vitamin C is 80mg
where the UK RNI is 40mg. When Nutriofia assesses your own intake in the
reports and trackers, it uses the age- and sex-specific UK values instead.
Fibre is shown without a percentage. Our fibre values use the UK
Englyst NSP method, while the published 30g daily goal is an AOAC figure — the two
are measured differently and a single percentage would mislead.
