Ingredients / Caffeine & caffeine sources

Caffeine

Also listed as: caffeine anhydrous, natural caffeine, di-caffeine malate, caffeine from green tea or coffee

What it is

A stimulant found naturally in coffee beans, tea leaves, cacao and guarana. "Anhydrous" just means the dry powder form. Caffeine made in a lab and caffeine extracted from a plant are the same molecule.

Why it is in energy drinks

It is the main reason people drink an energy drink: it is marketed for alertness and for less tiredness.

Worth knowing

The FDA says about 400 mg a day is not generally linked to negative effects for most healthy adults, but sensitivity varies a lot from person to person, and pregnancy, medications and heart conditions change the advice.
