Caffeine is mostly used in food and beverage. It’s a great addition to improving your body’s function and the quality of the drink. It helps you improve your overall function, assisting you with your school, work, and even workout.

With an appropriate amount of caffeine, you can improve your daily functions and be motivated at all times. It’s a lifesaver, especially during crucial times.

If you often play and usually engage in sports, caffeine may be a good companion to level up your performance. Energy drinks provide a boost that can help you strengthen your body and improve physical endurance. It helps you perform well and give your best during the game.

Caffeine increases your alertness and concentration by blocking your adenosine receptors from entering your brain.

The role of adenosine is to tell your body to take breaks, which is why your body will feel tired when adenosine enters your brain.

With caffeine, you will feel a sudden burst of energy that helps you manage your body.

Brain and Cognitive Functions

Caffeine can improve your thinking process and short-term memory. It helps you strategize effectively and handle your activities in your own way. It also plays an important role in slowing down your mental decline brought by age. It’s a good drink to cram for late-night studies and last-minute work.


The FDA has proposed a limit of 400mg of caffeine a day to manage the effect and symptoms of caffeine. It’s important to pay close attention to your consumption as excessive intake of caffeine can lead to health problems, like:

Caffeine Addiction

Excessive consumption of caffeine can lead to addiction. You need to moderate your caffeine intake as it might lead to addiction and dependency on caffeine. When your body becomes fully dependent on caffeine, you’ll not be able to function well without drinking caffeinated drinks.

Sleeplessness or Insomnia

Insomnia or sleeplessness is one of the side effects of caffeine. That’s why it’s advised not to drink caffeine hours before going to bed. Know that the half-life of caffeine in your body is five hours. Drinking too much can slow down your caffeine metabolism, which prevents you from getting a good night’s sleep.


Drinking too much caffeine can trigger your mood, which leads to an anxiety attacks and depression. The more caffeine you consume, the more susceptible you’ll be to having depression and anxiety.

How Long Does Caffeine Lasts?

Caffeine is a powerful stimulant, a minute of drinking it can give you an instant boost. In general, your body needs at least 5 hours to digest the half-life of caffeine. For example, if you consume 50mg of caffeine, you’ll still have 25mg of caffeine in your system after five hours.

There are several factors that affect the caffeine in your system. These factors include your age, health condition, and even genetics. Given that, the duration of caffeine varies from one person to another. Also note that 300mg of caffeine might not be healthy for children, pregnant women, or people with low caffeine tolerance.

In my experience, I always recommend that folks consume between 50 and 100 milligrams of caffeine. It is an enough quantity that will provide your body with the necessary fuel and stimulation to go through the day. Additionally, it is simpler to digest, and it helps you keep the right balance in your body so that you don’t have any crashes.

Is It Bad To Have 300mg of Caffeine Every Day?

The FDA provided a daily limit of 300mg of caffeine a day, so 300mg is the hard limit for the amount of caffeine you can have in a day. While 300mg is still within the limits, there’s a huge possibility of developing caffeine tolerance, which would lead to a craving for a higher caffeine dosage in the future.

The 300mg of caffeine that you consume every day can be problematic, especially if you’re not used to caffeine. Instead of getting the boost you need, you’ll end up feeling dizzy, unmotivated, and even more fatigued than when you started.

While it’s true that caffeine can help you boost your energy, continuously drinking the same amount can danger your health. So, my advice is, to drink strong energy drinks only when you really need them. Otherwise, stick to other beverages with lower caffeine content.

How to Manage Caffeine in your Body?

Caffeine build-up can be problematic because of its adverse effects. To manage that, here are some of the things that you can do to manage and release the caffeine in your body.

Know your Limitations

Consuming caffeine should also be backed up with knowledge. Make sure that you know your limitations to handle the effects. For example, if you notice that you’re starting to feel a bit light-headed or an increase in heart rate, it’s best to put down that energy drink even if you haven’t finished it yet.

While caffeine metabolism varies from one person to another, it’s still recommended to drink responsibly. Don’t wait until you’ve reached your limits.

Hydrate Yourself

Know that caffeine is a diuretic by nature, so it would be advisable for you to keep yourself hydrated. Increasing your water intake can help remove caffeine faster as it would increase your excretion, which would flush caffeine out of your body.

I would recommend keeping the caffeinated beverage to water ratio at a 1:1 rate. So, for every energy drink you have, you should try and have the same amount of water if you’re trying to shake off accidental jitters as quickly as possible.

Eat Healthy and Exercise

Considering caffeine is known to improve exercise performance, if you start getting jittery, it might be best to go for a quick run to metabolize the caffeine at a faster rate. Plus, you get to burn some calories in the process, making it a definite win-win situation.

Eating nutritious foods can help you get the energy and nutrients your body needs. It helps you improve your overall well-being.
