Caffeine is one of the primary stimulants that keep you alert and awake for a specific time. It aims to boost both your physical and mental awareness, and it helps you manage your overall condition to accomplish the tasks at hand. So, it’s no surprise that it is one of the primary ingredients in energy drinks.
While it’s undeniable that caffeine comes with various benefits, you might be wondering: how much caffeine is safe for consumption?
Caffeine gives your body an essential boost in every sip. However, the Food and Drug Authority (FDA) recommends a caffeine consumption of no more than 400mg of caffeine. This amount is enough for you to get the energy that you need throughout the day and won’t subject you to any side effects, such as caffeine addiction.
To know more about what caffeine can bring, here are the things that you need to bear in mind.
What Is Caffeine?
Caffeine is a natural stimulant most commonly found in plants like coffee and tea. It’s primarily used in food and beverages to improve your mental alertness and physical endurance.
Caffeine is also a psychoactive drug that boosts your brain activity and overall mental capacity. It stimulates the circulation of chemicals in your system like cortisol that keeps you active for a specific time. It’s a good addition to your food because it gives you a boost that can help you carry on for the entire day.
Fun Fact: About 80% of the population consumes caffeinated products every day. It helps them improve their concentration and focus to accomplish most of their tasks.
What Can You Get From Caffeine?
Caffeine doesn’t exactly have any nutritional value, and it’s also tasteless. That said, when your body consumes caffeine, it serves as a stimulant that activates your body’s physical and mental functions. While caffeine is beneficial, you should also be wary because too much caffeine can trigger health diseases.
Below is a brief table weighing the pros of caffeine against the cons when consumed in excess:
| Advantages | Disadvantages |
| Improve Brain and Cognitive Functions | Sleeplessness or Insomnia |
| Improve Alertness and Concentration | Increased Chances of Anxiety |

Benefits Of Caffeine
Caffeine acts as a central nervous system stimulant. When it reaches your brain, you’ll experience a burst of alertness running in your system. This happens because your body reacts to the stimulants brought by caffeine. The following are the other benefits of having caffeine:
Improve 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.
As energy drinks contain caffeine, it’s definitely a beneficial drink to have if you’re cramming for late-night studies and last-minute work.
Improve Alertness and Concentration
Caffeine increases your alertness and concentration by blocking your adenosine receptors from entering your brain. Know that once the adenosine receptors enter your brain, you will feel tired and want to rest. 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.
Improve Sports Performance
If you often take part 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.
Disadvantages of Caffeine
Caffeine is mostly used to improve mental alertness and physical endurance. However, it comes with disadvantages once you consume it in excess.
Note that excessive consumption of caffeine can lead to disastrous side effects. The FDA has recommended 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, such as:
Sleeplessness or Insomnia
Insomnia or sleeplessness is one of the side effects of caffeine. That’s why it’s not advisable 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.
Increased Chances of Anxiety
Caffeine is your partner to improve your performance and stay alert for a specific time. It gives you the energy and motivation to do your tasks. However, excessive consumption can lead to an increased heart rate, which can lead to increased anxiety.
You need to manage your consumption to avoid feeling jittery and restless and raise your anxiety levels. The less caffeine you consume, the calmer you will feel. It will help if you only drink caffeine occasionally or during important events.
Depression
Drinking too much caffeine can affect your mood negatively, which leads to anxiety attack and depression. The more caffeine you consume, the more susceptible you’ll be to having depression and anxiety.
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.
How Can You Manage The Effects of Caffeine?
Having too much caffeine is problematic for your body. To manage caffeine, here are the things that you can do.
Know your Limits
If you’re a caffeine lover, it would be best if you know your limitations. You should know your limits as knowing your limitation can help take the necessary precautions to prevent the side effects.
For example, if you notice that you’re starting to feel a little light-headed or have an increased 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 staying hydrated is essential. Increasing your water intake can help remove caffeine faster as it would increase your excretion, which would flush caffeine out of your body.
Know that nothing beats water when it comes to proper hydration. It can help you refresh and improve your overall wellness.
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 any unwanted jitters as quickly as possible.
Eat Healthy and Exercise
Consuming caffeine can effectively improve your exercise performance. But, 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, which makes 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 body’s overall capacity.
Is 600mg of Caffeine Too Much?
Considering the recommended consumption of the FDA, consuming 600mg of caffeine might be too much for your body. Continuous consumption of such excessive caffeine will lead you to no longer be able to feel the boost with a smaller amount, and you’ll just keep wanting for more.
There is a huge possibility of developing caffeine tolerance, and caffeine crashes. Instead of improving your performance, which ultimately slows you down. Make sure to consume only the amount your body needs. Don’t assume that having a lot of caffeine is beneficial, because having too much has its negative effects.
Is Caffeine Bad for Your Heart?
Caffeine is a good stimulant but it can greatly stress your heart if you drink too much.
Note that consuming caffeine in moderation can lead to positive effects on your system. However, it has also its bad sides. Caffeine increases your body’s cortisol production, which can lead to anxiety, heart disease, and even weight gain.
The sudden increase of cortisol in your system can increase your blood pressure which is not good for your heart. Regulating your consumption is a must to keep you at safe levels. Help yourself by managing your body’s caffeine.
Caffeine is good for your body as long as you have minimal consumption. So, I would recommend that you set a specific level of consumption to avoid disastrous side effects.
How Long Does Caffeine Last?
Caffeine is a powerful body stimulant, you can get an instant boost a minute of drinking it. 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.
Several factors affect caffeine absorption in your system. These factors include your age, health condition, and even genetics. Given that, the duration of caffeine’s effect may vary, you should never dive into strong energy drinks without knowing your limits first. If you have low caffeine tolerance, you should not consume too much caffeine a day.
It’s also advisable to manage your caffeine consumption if you’re pregnant. Children should not consume caffeine carelessly because their bodies can handle its effects.
Personally, I always prefer a caffeine content of about 50mg to 100mg as I find it to be the appropriate amount that’s enough for your body to get the boost for the day. Your body can manage it easily, so you don’t need to worry about caffeine crashes or any other caffeine-related side effects.
How much caffeine is too much for a teenager
The amount of caffeine that is considered harmful for teenagers depends on the tolerance of the teenager. Other factors such as age, weight, and health must also be considered.
Although it is mostly safe for teenagers to have caffeinated drinks, they still have to take them in moderation to avoid health risks.
