Caffeine and other substances that are commonly found in energy drinks are added to teas by the brand Zest. It doesn’t always follow, though, since it can’t provide the same energy boost as energy drinks.
Zest Energy Teas are available in cans and teabags, come in a variety of flavors, and can give you an energy boost without making you jittery.
In addition, Zest Energy Teas have little to no sugar and are plant-based, vegan, keto-friendly, and gluten-free. Zest Energy Teas include up to 150 mg of caffeine along with healthy nutrients including ginger root extract.
