                                In Canada, energy drinks are strictly limited to a maximum of 180 mg of caffeine per serving, a regulation enforced by Health Canada for supplemented foods. This rule is one of several that define precisely how much caffeine can be in a drink in Canada, encompassing not only energy drinks but also sodas and other beverages.
