Take your body weight (Let’s say 220 lbs)


Divide that number by 2.2 (220 / 2.2 = 100)


Take the number found in step 2 above, and multiply it by 3 (100 x 3 = 300)


This number is the maximum amount of caffeine in milligrams that you should consume.

So in this case, our calculator shows that if you’re 220lbs, you should not be drinking more than 300mg of caffeine per day.

What is caffeine and how does it work in the body

Caffeine is a stimulant. It is a naturally occurring chemical found in coffee beans and other foods, drinks, and medicines. It can also be artificially synthesized for use in certain medicines. Consumption of caffeine increases alertness and activates the nervous system, temporarily warding off drowsiness and restoring mental alertness. This effect begins approximately 15 minutes after consumption but may take up to 2 hours before experiencing a full effect.

According to Cleveland Clinic, caffeine has a half life upto 6 hours. That means that after consuming caffeine at 8 AM one morning it could potentially take you until 2pm before the body eliminates 50% of it!

Caffeine was approved as a food additive in 1958 because it has been found to dissolve easily in water and mix well with other ingredients. Caffeine is often associated with coffee, due to its high concentration in coffee beans.

However, caffeine can be found in other ingredients that are commonly added to many products consumed every day including tea leaves, guarana seeds, cocoa beans, kola nuts, and yerba mate leaves. These are all considered dietary supplements because they contain naturally occurring levels of caffeine.


Caffeine tolerance calculator - How many cups of coffee can I have per day without getting jittery or having a heart attack? 

How long does caffeine last calculator will help you figure out how many cups of coffee you can have each day without being overstimulated, experiencing negative health effects from caffeine, or having a heart attack.

The amount of caffeine that is safe to consume in a day varies from person to person. But if you're a heavy coffee drinker who has a high tolerance, don't take it for granted! Much like any other drug, too much caffeine over time could be bad for your health and could even cause death*.

Fortunately, there are steps that you can take to prevent the negative health effects of caffeine.

For example, when you're consuming caffeine in high amounts it's suggested that you take a break every once in a while to allow your body to adjust and lower your tolerance. However, be careful if you go cold turkey, and completely stop drinking caffeine. Caffeine withdrawal is real, and can cause irritability, nausea, and headaches. Therefore, gradually taper off once in a while.

It's also important to keep in mind how different types of caffeinated products affect people differently - some might get jittery or suffer from palpitations whereas others may feel nothing at all. That's why it's very important that you know exactly what affects you personally!

Keep in mind that everyone's tolerance for caffeine is different so even though some people can handle much more than others, remember that everyone has a limit. This caffeine calculator will help you know how much caffeine is safe for you, so it's important to be aware of your own limits!


What should I know about the dangers of too much caffeine? - How can one overdose on caffeine?

There are some people who suffer from chronic overconsumption, which means that they have been consuming large amounts of caffeine daily for weeks or months.

Caffeine has a half-life in the body of up to 6 hours, meaning that half of the amount consumed at 8 am could still be in your system at 2 pm. With this type of long-lasting effect, there are serious consequences when you're drinking too much coffee and tea on a regular basis. Chronic over-consumption can lead to caffeine intoxication, which is when you have more than 400 milligrams of caffeine in your body.

Caffeine toxicity can cause symptoms that are similar to poisonings, such as vomiting, palpitations, and tremors. Symptoms of caffeine overdose include abdominal pain, delirium, disorientation, diarrhea, dizziness/lightheadedness, excessive urination or diuresis, hallucinations, or neuromuscular tremors. If the body has too much caffeine it could suffer from cardiac arrest.

It's important to be aware that some medications also contain caffeine. Taking medication with even 50mg of caffeine could mean ingesting around 200 mg if you're sensitive to it - double the recommended daily intake! That's why it's also important to check the caffeine content of what you're taking.


How does caffeine affect sleep?

Caffeine blocks adenosine receptors, which is a molecule that makes our bodies tired. This means that when we ingest lots of caffeine, our bodies won't be able to trigger the chemical reactions that send us signals to feel tired or sleepy. This is why many people experience alertness after drinking coffee or tea.

Adenosine builds up in our blood throughout the day before increasing at nighttime, which causes melatonin levels to increase and allows us to fall asleep naturally. When caffeine disrupts this process by blocking adenosine receptors, melatonin levels remain low and this causes difficulty falling asleep, insomnia, and sleep deprivation.


How much caffeine is safe to consume daily?

The FDA says that 400 mg of caffeine each day is the limit for healthy people over 17 years old, and this equals about four (8 fl. oz.) cups of coffee or 10 (8 fl. oz.) cans of cola! It's important not to exceed this amount because consuming more than 400mg can lead to unpleasant side effects such as jitteriness, insomnia, and heart palpitations, among others.


What happens if you don't drink enough water and take too much caffeine?

Caffeine has diuretic properties, meaning it makes you urinate more frequently. If your body doesn't get enough water, it could lead to a lowering of the potassium levels in the body, which could cause serious health problems. If you drink too much caffeine and don't get enough water, you could actually die!

It's important to stay hydrated when consuming caffeine, especially if you're planning on doing any sort of physical activity.


How much caffeine is in caffeinated beverages?

The amount of caffeine in coffee depends on the type of bean used, how it's prepared and how concentrated it is. The average cup of brewed coffee contains about 100 mg, although there are many varieties that have more than 200mg!

A standard "energy shot", like 5-Hour Energy, has around 215 milligrams of caffeine for every serving (2 fluid ounces). Energy drinks usually contain around 80-150 milligrams per 8 ounces serving so drinking one or two energy drinks daily would be within the daily limit of caffeine intake as long as you don't exceed the suggested serving sizes on each container.

There are some additional risks to be aware of if you're drinking too much caffeine. Caffeine is a stimulant that can increase your heart rate, which can cause cardiovascular problems like heart palpitations, irregular heartbeat, and chest pain. It can even cause a heart attack in some cases! Consuming too much caffeine can also lead to increased anxiety and restlessness, which means you'll take longer to sleep and feel tired the next morning.

It's also important to remember that caffeine can be very addictive. If you're drinking coffee, tea, or energy drinks on a daily basis and feel like cutting back, read about the withdrawal symptoms of caffeine: headache, irritability, and lethargy.


Energy Drinks and Caffeine Consumption

Energy drinks have a very high caffeine content because they combine natural caffeine from coffee beans as well as synthetic caffeine which is created in a lab.

But the most worrisome effect is that it may cause you to have an increase in your blood pressure which can lead to an increased risk of having a heart attack.

If you're going to drink energy drinks, then it's best that you understand the caffeine amount of each type and how much caffeine is too much for you. Additionally, energy drinks contain a lot of sugar and tons of artificial ingredients, so it is important to also read the sugar content for each drink.

The FDA has recently recommended more research on energy drinks as a concern as to whether or not they are safe for consumption.


Can you drink coffee while pregnant?

While the American College of Obstetricians and Gynecologists recommends pregnant women to reduce their caffeine intake to as little as possible (lower than 200 mg or 2 cups per day), Dr. John Foxe, PhD, director, Del Monte Institute for Neuroscience, University of Rochester, recommends going decaf and trying to eliminate caffeine altogether.

This also depends on the side effects of going cold turkey and cutting out caffeine altogether, as it could cause withdrawal, irritability, stress and anxiety and they can have effects on a pregnancy. Although pregnant women have been advised to limit their caffeine intake in order to reduce their risk of miscarriage or preterm birth for many years, a new study suggests that pregnant women who consume any coffee during pregnancy may be more likely to have children who develop behavioral problems later in life.

Brain scans of children whose mothers drank caffeine while pregnant revealed abnormalities in circuits that could lead to behavioral disorders later in life, such as attention difficulty and hyperactivity, according to the researchers.


How do I cut down on caffeine?

Firstly, know that if you just stop drinking caffeine all at once, it may lead to withdrawal symptoms like headache, irritability, fatigue, and nausea. If you're going to cut back make sure to do so slowly over time by mixing caffeinated and non-caffeinated beverages together gradually until eventually, you are not getting any caffeine in your diet. You can also replace caffeinated beverages with healthier drinks such as tea or water. If you drink coffee only because you are tired, it is best that you go for a balanced diet to increase your energy levels, and get proper sleep at night.
