What Is Caffeine?

Caffeine is a naturally occurring stimulant in different natural substances and products. You can get caffeine from more than 60 plants, from coffee to chocolate. Caffeine is a stimulant for your brain and nervous system to increase activity and performance.

Since caffeine is a chemical substance, we can define it in the same language:

An alkaloid compound that naturally occurs in different plants that work as a stimulus for the central nervous system. Coffee plants and tea plants are the most popular sources of caffeine.

If we talk about the taste and essence of caffeine, it is a bitter substance. The bitterness in coffee, cocoa, and tea is due to the presence of caffeine in it. Usually, naturally occurring caffeine is consumed around the world, but there is a synthetic one as well.

How Does Caffeine Work On Your Body?

We all know that caffeine is a stimulant that works on our central nervous system and brain. But how does it actually work on your body?

Here is a simple explanation of how caffeine goes into your body and provides a sudden boost of energy to stay active and improve your overall performance in daily life.

When you consume caffeine, your body will absorb it within 45 minutes. The caffeine peak in your blood is between 15 minutes to 2 hours. One serving of caffeine can work on your metabolism for about 2 hours.

So how does caffeine is absorbed by your body?

The caffeine you take in beverages is quickly absorbed and dissolved in your body’s water and fat molecules. It also crosses into your brain. How caffeine absorbs in your gut depends on different factors, and food is one of them. The type of food you have consumed can slow the absorption process.

If you drink coffee on an empty stomach, it quickly absorbs in your gut and gives you a quick energy boost compared to when drinking coffee after or with breakfast.

The breakdown of caffeine takes place in the liver. The time for coffee to remain in your blood is around 2 to 9 hours. However, if you are a smoker, the breakdown of caffeine is faster, but pregnancy slows down caffeine breakdown in the body.

What Amount Of Caffeine Is Safe For Adults?

If we talk about the safe consumption limits of caffeine in adults, the U.S. Food and Drug Administration has a recommended limit for that purpose.

According to the stats, the average caffeine consumption per person is 135 mg/day in the U.S. However, anywhere under 400 mg of caffeine is considered safe consumption for adults. It equals 4 cups of brewed coffee.

Pregnant women have an exception and should not consume more than 200 mg of caffeine daily. Children under the age of 12 should not consume caffeinated beverages or food.

Below 18 and above 12 children should not consume more than 100 mg of caffeine daily. These recommendations have been issued by the American Academy of Pediatrics.

Is it Safe To Take 600 mg of Caffeine At Once?

As mentioned, 400 mg of caffeine per day is considered the safe limit. Therefore, it is clear that 600 mg of caffeine per day, whether taken at intervals or at once, is not safe at all. There are several short-term and long-term implications for this practice.

The instant effects of consuming 600 mg of caffeine at once or in a day can be shaking, short-term insomnia, agitation, irregular heartbeat, restlessness, irritability, and nervousness.

There might be long-term implications of consuming more than 600 mg of caffeine every day, ranging from chronic insomnia to continuous depression & anxiety. It can also trigger stomach problems, high blood pressure, and an increased risk of miscarriages in women.

Therefore, it is not at all safe to consume more than 600 mg of caffeine at once. You should always consume caffeine in moderation to get energy without compromising your health.

What Are Side Effects Of Caffeine Overdosage?

When taken in moderate amounts, caffeine is not dangerous nor poses health risks. However, overdosage for extended periods or consuming caffeine for a longer period can have some side effects on certain people.

How Much Coffee Is Enough Based On Caffeine Intake?
