Caffeine Content in Diet Cola Soft Drink
Caffeine Amounts in Soda: Every Kind of Cola You Can Think Of
Cola is a popular flavor of soda around the world. Although the kola nut, from which the flavor of cola soda comes from, does naturally contain caffeine, the majority of the caffeine in cola is added by the manufacturer.
Colas typically contain between 30-50 mg of caffeine per 12 fl oz (355 ml). However, there are a few exceptions as listed below.
These caffeine amounts are from an extensive lab test (done in 2007). While being out of date, it is still one of the most comprehensive caffeine testing of sodas done in recent decades.
