black tea energy

Caffeine primarily comes from black tea leaves or black tea extract. Some products also include other tea-derived ingredients such as yerba maté, and ready-to-drink cans typically list the total caffeine amount contributed by the tea blend.

When manufacturers list exact amounts, servings typically provide about 61–80 mg of caffeine per serving.

Some blends include herbal ingredients like yerba maté and adaptogens such as ashwagandha. Certain ready‑to‑drink cans also list B vitamins intended to support steady energy.

Common labels include USDA Organic, Rainforest Alliance Certified, Non‑GMO, Kosher, Vegan, Gluten‑Free, and (on some brands) Certified B Corporation.

Many items are formulated for both hot and iced use—tea bags often note suitability for hot or iced preparation—though a few caffeinated blends are described as best enjoyed hot.
