Caffeine
Also known as: contiene cafeína
A natural stimulant that's safe in normal drink amounts but risky in concentrated or excessive doses.
Caffeine is a stimulant found naturally in coffee, tea, and cacao, and added to many sodas and energy drinks. Typical servings are safe for most healthy adults, but high doses, sensitive individuals, children, and pregnant people need to be more careful.
Why it matters
Caffeine is a naturally occurring stimulant that blocks a brain chemical (adenosine) that makes you feel sleepy. It speeds up your heart rate, increases alertness, and is mildly addictive - regular users can get withdrawal headaches or fatigue if they stop suddenly. Most healthy adults tolerate normal amounts well, but people with heart conditions, anxiety disorders, pregnant people, and children should pay more attention to how much they consume.
