What Is Caffeine and Where Can It Be Found?
Caffeine is a bitter, white crystalline xanthine alkaloid that acts as a central nervous system stimulant. It is found naturally in the leaves, beans, and fruit of more than 60 plants, including coffee trees, tea bushes, and cacao trees.
It is also added to many manufactured foods and beverages such as soft drinks, energy drinks, sports drinks, and even some over-the-counter medications.
How Does Caffeine Work?
Caffeine works by blocking the action of adenosine on your brain cells. Adenosine is a neurotransmitter that promotes sleepiness and relaxation. When caffeine blocks adenosine from binding to its receptors, it causes an increase in alertness and energy levels.
What Are the Effects of Caffeine?
The effects of caffeine vary from person to person. Some people may feel more alert and energetic after consuming caffeine, while others may experience jitters, anxiety, or insomnia.
Caffeine is also a diuretic, which means that it increases urine output. This can lead to dehydration if you are not drinking enough fluids throughout the day.
How Much Caffeine Is Safe to Consume?
Most healthy adults can safely consume up to 400 milligrams of caffeine per day. However, pregnant women and people with certain medical conditions should limit their intake to 200 milligrams per day.
It is important to note that the amount of caffeine in a food or beverage can vary widely. For example, a cup of brewed coffee can contain anywhere from 95 to 200 milligrams of caffeine.
When Is the Best Time to Consume Caffeine?
The best time to consume caffeine depends on your sleep patterns and needs. If you are trying to improve your alertness during the day, it is best to consume caffeine in the morning or early afternoon.
If you are trying to improve your performance during exercise, it is best to consume caffeine about 30 minutes before you start working out.
