Is koffein vegan?

Caffeine, also known as koffein, is a naturally occurring stimulant found in the seeds, leaves, and fruits of some plants. It is widely consumed by humans in the form of coffee, tea, chocolate, and energy drinks. Caffeine is known for its ability to increase alertness, improve concentration, and enhance physical performance. It works by blocking the action of adenosine, a neurotransmitter that promotes sleep and suppresses arousal. Caffeine can have both positive and negative effects on health, depending on the amount consumed and individual sensitivity. While moderate intake is generally safe for most people, excessive consumption can lead to anxiety, insomnia, and other health problems.
