45Mg Caffeine: Comprehensive Guide to Caffeine Content in Popular Beverages
How much caffeine is in your favorite drinks. What are the health effects of consuming caffeine. How to manage your caffeine intake for optimal health and energy. Which beverages contain the most and least caffeine.
Understanding Caffeine Content in Common Beverages
Caffeine is a widely consumed stimulant found in various beverages, from coffee and tea to energy drinks and sodas. Understanding the caffeine content in these drinks is crucial for managing your daily intake and avoiding potential side effects. This comprehensive guide explores the caffeine levels in popular beverages, helping you make informed decisions about your consumption.
Caffeine in Coffee
Coffee is one of the most popular sources of caffeine worldwide. The caffeine content in coffee can vary significantly depending on factors such as the type of beans, roast level, brewing method, and serving size.
- Brewed coffee: 95-200 mg per 8 oz cup
- Espresso: 63 mg per 1 oz shot
- Instant coffee: 30-90 mg per 8 oz cup
- Decaf coffee: 2-12 mg per 8 oz cup
One notable example of high-caffeine coffee is Black Label Brewed Coffee from Devil Mountain Coffee Company. This highly caffeinated blend contains a staggering 1,555 mg of caffeine per 12 fl oz cup, making it one of the strongest coffees available on the market.
Caffeine in Tea
Tea is another popular caffeinated beverage, with varying levels of caffeine depending on the type and brewing method.
- Black tea: 14-70 mg per 8 oz cup
- Green tea: 24-45 mg per 8 oz cup
- White tea: 6-60 mg per 8 oz cup
- Oolong tea: 12-55 mg per 8 oz cup
Steeping time significantly affects the caffeine content in tea. For example, a study of various black tea brands showed that caffeine levels increased with longer steeping times:
- 1-minute steep: 14-59 mg
- 3-minute steep: 22-59 mg
- 5-minute steep: 25-61 mg
It’s important to note that herbal teas, which are not derived from the Camellia sinensis plant, do not contain caffeine unless it’s added artificially.
Exploring High-Caffeine Beverages
In recent years, there has been a surge in the popularity of high-caffeine beverages, particularly energy drinks and specialty coffees. These products cater to consumers seeking an extra energy boost or those with high caffeine tolerance.
Energy Drinks
Energy drinks are known for their high caffeine content, often combined with other stimulants and sugars. Some popular energy drinks and their caffeine content include:
- Bang Energy: 300 mg per 16 fl oz can
- Monster Energy: 160 mg per 16 fl oz can
- Red Bull: 80 mg per 8.4 fl oz can
- Starbucks Triple Shot Energy: 225 mg per 15 fl oz can
Specialty High-Caffeine Coffees
Some coffee brands specialize in producing extremely high-caffeine blends. These products should be consumed with caution and only by individuals with high caffeine tolerance:
- Black Label Brewed Coffee: 1,555 mg per 12 fl oz cup
- Death Wish Coffee: 728 mg per 12 fl oz cup
- Black Insomnia Coffee: 1,105 mg per 12 fl oz cup
Factors Affecting Caffeine Content in Beverages
The caffeine content in beverages can vary due to several factors:
- Bean or leaf variety: Different coffee bean and tea leaf varieties naturally contain varying amounts of caffeine.
- Roasting process: Contrary to popular belief, lighter roasts often contain slightly more caffeine than darker roasts.
- Brewing method: Espresso and French press methods typically extract more caffeine than drip brewing.
- Serving size: Larger servings naturally contain more caffeine.
- Steeping time (for tea): Longer steeping times result in higher caffeine extraction.
- Water temperature: Hotter water extracts caffeine more efficiently.
Health Effects of Caffeine Consumption
Caffeine consumption can have both positive and negative effects on health, depending on the amount consumed and individual tolerance levels.
Potential Benefits
- Increased alertness and focus
- Improved physical performance
- Potential protective effects against certain diseases (e.g., Parkinson’s, type 2 diabetes)
- Antioxidant properties (particularly in coffee and tea)
Potential Risks
- Insomnia or sleep disturbances
- Anxiety and restlessness
- Increased heart rate and blood pressure
- Digestive issues
- Caffeine dependence and withdrawal symptoms
Is there a recommended daily limit for caffeine intake? The FDA suggests that healthy adults can safely consume up to 400 mg of caffeine per day. However, individual tolerance levels may vary, and some people may be more sensitive to caffeine’s effects.
Managing Caffeine Intake for Optimal Health
To enjoy the benefits of caffeine while minimizing potential risks, consider the following strategies:
- Monitor your intake: Keep track of the caffeine content in your beverages and stay within recommended limits.
- Be mindful of timing: Avoid consuming caffeine late in the day to prevent sleep disturbances.
- Stay hydrated: Balance caffeinated beverages with water intake.
- Consider your individual sensitivity: Pay attention to how caffeine affects you personally and adjust your consumption accordingly.
- Gradually reduce intake if necessary: If you’re consuming too much caffeine, slowly decrease your intake to minimize withdrawal symptoms.
Alternatives to High-Caffeine Beverages
For those looking to reduce their caffeine intake or find alternatives, consider the following options:
- Decaf coffee and tea
- Herbal teas (e.g., chamomile, peppermint, rooibos)
- Caffeine-free sodas
- Sparkling water with natural flavors
- Fruit-infused water
- Golden milk (made with turmeric and other spices)
- Kombucha (contains minimal caffeine)
The Future of Caffeine in Beverages
As consumer preferences and health awareness evolve, the beverage industry continues to innovate in the realm of caffeinated drinks.
Emerging Trends
- Natural energy drinks: Beverages made with natural caffeine sources like guarana and yerba mate
- Functional beverages: Drinks that combine caffeine with other beneficial ingredients (e.g., adaptogens, vitamins)
- Low-caffeine alternatives: Development of coffee and tea varieties with naturally lower caffeine content
- Personalized caffeine solutions: Products tailored to individual caffeine tolerance and preferences
How might these trends shape the future of caffeinated beverages? As consumers become more health-conscious and seek personalized solutions, we may see a shift towards more diverse and tailored caffeine options in the market.
Conclusion: Making Informed Choices About Caffeine Consumption
Understanding the caffeine content in various beverages empowers consumers to make informed decisions about their intake. Whether you’re a coffee enthusiast, tea lover, or energy drink consumer, being aware of the caffeine levels in your favorite drinks allows you to balance enjoyment with health considerations.
Remember that moderation is key, and individual responses to caffeine can vary. By staying informed and mindful of your consumption, you can harness the benefits of caffeine while minimizing potential risks. As the beverage industry continues to evolve, staying up-to-date on new products and trends will help you navigate the ever-expanding world of caffeinated drinks.

The caffeine amounts in tea can vary considerably. The longer the tea (or tea bag) is steeped in water, the more caffeine will be present.
On average loose black tea has 22-28 mg of caffeine per 1 gram dried matter.
Most tea manufacturers do not list caffeine amounts on labels (one exception is Lipton regular tea listed at 55 mg per serving).
The amount listed above is an average amount taken from various laboratory tests. Originally we listed an amount (47 mg/8 fl oz brew) taken from the USDA. However more recent lab tests show this amount to be lower.
The following table lists recent lab test results for one tea bag of the various brands steeped in 6oz cups of water.
Tea | 1 Min Steep Time | 3 Min Steep Time | 5 Min Steep Time |
---|---|---|---|
Lipton Decaf* | 1.8 mg | 2.7 mg | 3.1 mg |

What About Herbal Teas?
So-called herbal teas aren’t actually tea at all, but a collection of other herbs and flavors. Herbal teas do NOT contain caffeine.
What About Green Tea?
Green Tea contains less caffeine than black tea. However it also is affected by brew time. The longer you leave your bag in the cup, the more caffeine you will get.

How much caffeine is in a cup of coffee beans: table
It’s no secret that coffee is an invigorating drink. After all, it is precisely because of this property that we drink it in the morning, right? It’s all about caffeine – an alkaloid found in many plants: coffee, tea, cocoa, cola. It helps plants to protect themselves from insects. And in humans, it stimulates the nervous system, causes the expansion of blood vessels, enhances cardiac activity … Due to these properties, caffeine is often used in medicine. This alkaloid can be seen in formulations for migraine medication, for colds, to stimulate mental and physical activity.
And if a cup of, for example, americano in the morning or at lunch is beneficial, then excessive consumption of the drink leads to devastating consequences for the body. And where is this line?
In 400mg of caffeine. This is an established norm that does not harm a person. But after all, on a mug with a drink it is not written how much an invigorating substance is contained there? How to determine the norm? Let’s figure out how much caffeine is in a cup of coffee.
First, let’s make a reservation that each variety has its own strength, and hence the amount of alkaloid contained. The two most common are Arabica and Robusta. The first option has at least 60 mg of caffeine, the second about 120 mg. But in addition to the variety, indicators such as the method of roasting, grinding and the method of brewing the drink also affect.
Thus, there are 4 types of roast:
- Weak – it will taste sour;
- Medium – has a bright aroma and sourness;
- Between medium and dark – has a rich taste with sweetish-bitter notes;
- Dark – intense taste and smell, possible bitterness.
Dark roasts may taste like they have the highest caffeine content, as they are quite rich and can even be bitter. But this is a myth. During processing, caffeine burns out, so in a dark roast it is not so much, but in a weak one it is the maximum amount.
There are also 4 types of grinding:
- Coarse – like sea salt;
- Medium – like river sand;
- Thin – like coarse flour;
- Superfine – looks like powdered sugar.
Here the gradation goes from the highest to the lowest caffeine content. The reason is that due to the grinding of grain, the amount of alkaloid decreases.
Finally, let’s take a closer look at the dependence of the caffeine content on the method of brewing the drink. How much caffeine is in a cup of coffee beans?
- Fans of a natural Turkish drink will be curious to know that a liter of drink prepared in this way contains from 380 to 650 mg of caffeine. Therefore, a standard cup of 200 ml is 76 – 130 mg of an invigorating substance.
- Slightly more in a mug made in a drip coffee maker – 145 mg.
- French press drink contains up to 200 mg of alkaloid.
- In instant coffee 310 – 480 mg active ingredient per litre. So the circle will be 62 – 96 mg enzyme.
- Espresso is a fairly strong drink. Which is not surprising, because caffeine here is from 1700 to 2250 mg per liter. A standard espresso cup is 75 ml, so one serving will have between 127 and 168 mg.
Don’t forget espresso drinks. We are talking about americano, latte and cappuccino.
- Americano contains 715 to 970 mg of caffeine per litre. A standard serving is 120 ml, which means there are 85-117 mg of the substance here.
- Latte is 500-900 mg alkaloid. 400 ml of this drink is 200 – 360 mg of cheerfulness.
- Cappuccino suggests 500 – 680 mg of caffeine. The 200 ml standard refers to 100-136 mg of enzyme per serving.
We should also highlight decaffeinated coffee. It would be naive to believe that the invigorating component is completely absent in a decaffeinated drink, but its content is significantly reduced: 12-13. 4 mg per serving. The plus is that despite the branded taste, such a drink is suitable for hypertensive patients and even pregnant women.
The table shows how many servings of a particular drink can be consumed per day.
Beverage preparation method | Caffeine content per serving | Permissible quantity servings per day |
Instant coffee | 62-96 mg per 200 ml | 4 to 6 |
Turk | 76-130 mg per 200 ml | 3 to 5 |
Drip coffee maker | Up to 145 mg per 200 ml | Up to 2 |
French press | Up to 200 mg per 200 ml | Up to 2 |
Espresso | 127-198 mg per 75 ml | Up to 2 |
Americano | 85-117 mg per 120 ml | 3 to 4 |
Latte | 200-360 mg per 400 ml | 1 to 2 |
Cappuccino | 100-136 mg per 200 ml | 2 to 4 |
Decaffeinated | 12-13. 4 mg per 200 ml | From 29 to 33 (but it’s better not to get carried away) |
If you don’t like the taste of coffee, but want to cheer up, tea will come to the rescue. Black, for example, contains about 27 mg of caffeine per 100 ml, and green about 30. Three to four servings of a leafy drink contain as much caffeine as coffee beans. Other natural variations for a bouncy morning include ginger, cocoa, ginseng, and chicory.
By observing the daily intake of caffeine, you can drink your favorite drink without harm to your health without any consequences for the body.
Dose of caffeine | FPA
Author – Natalia Reznik.
In our hectic time, when there is so much to do, many resort to tonics. One of the most famous and affordable is caffeine. However, they must be used with caution. The May issue of Examine.com talks about the benefits and dangers of this stimulant.
Caffeine has been used for a very long time. Its source in India and the countries of the Middle East was coffee; in China, India and Southeast Asia – tea; in America, the yerba mate plant, cocoa beans, guarana leaves, and kola nuts. These days, caffeine is often added to sugary sodas, energy drinks, and weight loss supplements. The vast majority of people use some form of caffeine. In 2016, for example, they drank 7 million tons of coffee. The sale of energy drinks is also on the rise, and Figure 1 shows the caffeine content of some popular products. In drinks poured into cans and bottles, it is standard, but in a cup of coffee it can vary markedly.
Fig. 1 Where and how much do we get caffeine.
What is the overdose?
There is no exact answer to this question – the safe dose of caffeine depends on the state of health. Some people drink strong coffee all day without any harmful effects, while others have a pressure jump from a single cup, sleep is disturbed, their head hurts and their nerves are naughty. True, caffeine-induced nervousness can be alleviated by the amino acid L-theanine, which is found in green tea leaves. Interestingly, similar symptoms are observed in people with caffeine withdrawal. And they also yawn, complain of fatigue, runny nose, muscle stiffness, it is difficult for them to concentrate. Alas, caffeine cannot be considered a completely safe product.
Healthy Adults – Reasonably Allowed
Authoritative organizations such as the European Food Safety Authority (EFSA), the US National Academies of Sciences (NAS) and Health Canada have concluded that healthy adults can safely consume up to 400 mg of caffeine per day. More than 400 mg can be taken on special occasions (for example, during emergency preparation for an exam). Such a dose will not cause side effects if such force majeure occurs rarely.
The effects of caffeination depend on the time of intake. Most people can drink 200 mg of caffeine at a time less than 2 hours before intense exercise. However, even 100 mg can disturb sleep if you drink coffee or an energy drink at night. Caffeine leaves the body quite slowly, the half-life is about five hours, so people who drank strong coffee less than 10 hours ago still have some amount of alkaloid roaming in the blood.
So, healthy adults can consume up to 400 mg of caffeine per day, but not at bedtime.
Pregnant and lactating women – handle with care
The European Food Safety Authority recommends that lactating and pregnant women, as well as those who are just planning a pregnancy, limit their daily intake of caffeine to 200 mg. Some experts allow up to 300 mg / day, however, according to some reports, caffeine causes nausea in pregnant women and, much worse, the risk of miscarriage.
There are very few clinical studies on the effects of caffeine on pregnant and lactating women, and in such a situation it is wiser to limit the intake of alkaloid. In pregnant women, the time required to remove caffeine from the body increases by more than three times, so caffeine can accumulate: drunk in the evening is added to what has been preserved in the morning, and the total dose of the substance circulating in the blood is higher than the calculated one.
So, pregnant and lactating women should not exceed the daily dose of 200 mg, although they are allowed 300 mg.
Children and adolescents should refrain
Data on safe doses of caffeine for children and adolescents is clearly insufficient. According to European experts, young consumers will not be harmed by 3 mg / kg of body weight per day. In Canada, no more than 2.5 mg/kg/day is considered safe. In accordance with these standards, children, depending on age, are allowed to:
- 4-6 years – 45 mg/day
- 7-9 years – 62.5 mg/day
- 10-12 years 85 mg/day.
Not everyone agrees with this opinion. So, in 2013, a group of honored American doctors sent a letter to the US Food and Drug Administration calling for a ban on the sale of caffeinated drinks in schools. Scientists point out that
caffeine concentrations in energy drinks are strongly correlated with adverse health outcomes in children, adolescents, and young adults.
So the safe level of caffeine for children and adolescents has been determined, but some medical organizations are calling for more thorough research on this issue, and until the data is collected, the less caffeine the child consumes, the better.
If you suffer from heart disease, consult your doctor
Caffeine increases blood pressure for 3-4 hours, this is a proven fact. However, with regular consumption, this effect is not so noticeable. In healthy people who do not exceed the allowed 400 mg, the risk of developing cardiovascular disease does not increase. But for people with high blood pressure or those who have already suffered cardiovascular disease, in other words, for patients who are contraindicated in stimulants, the consequences of caffeine intake are not so obvious. Moderate amounts will not hurt them, but it is best to consult a doctor about specific doses.
So, for people with high blood pressure or who have had cardiovascular diseases, regular consumption of caffeine-containing drinks is not indicated. There should be no harm from small portions, but it is better to consult.
How much do you have to drink to hit your caffeine limit?
To answer this question, you need to know how much caffeine is in each cup/can/bottle you drink. This information is contained in Figure 1, but for those who find it difficult to concentrate without caffeine, as well as for adherents of a mono-diet (as they started the day with coffee from McDonald’s, they won’t take anything else caffeinated in their mouths) there is also Figure 2.
Fig. 2 How many and what drinks can you drink so as not to exceed the daily caffeine limit of 400 mg.
And what happens if you sort it out?
When taken orally, 15 mg of caffeine per kilogram of body weight is toxic, and 150 mg is lethal. That is, a person who weighs 68 kg will be poisoned by one gram of caffeine, and will die from 10 g. Think about it before drinking 10 cans of energy drinks on a bet.
Powdered caffeine is a special song. It is used as a nerve stimulant and advertised as a fitness and muscle builder, and some people take it arbitrarily for that purpose. The US Food and Drug Administration warns that one teaspoon of pure caffeine powder is equivalent to 28 cups of coffee. To allow an overdose of powder is much easier than to overdrink energy drinks. A large amount of caffeine increases the activity of the sympathetic nervous system, causes a strong heartbeat and convulsions.
While caffeine powder poisoning is rare, it does happen, and sometimes fatally. Both athletes who independently take this substance and specialists are mistaken. So at the University of Northumbria, scientists, conducting an experiment, accidentally gave two students 30 grams of caffeine instead of 300 mg. The students, fortunately, survived, but they had to spend some time in the hospital.
If you are healthy, you can safely drink drinks containing caffeine, guided, of course, by figures 1 and 2, but it is better not to deal with the powder.
The best thing to do
All of the above recommendations are based on the long-term effects of regular caffeine intake. Higher doses, up to 800 mg, may be taken on special occasions if health permits. So, in one study
rugby players took different doses of caffeine before training. The alkaloid increased the content of testosterone in the blood, that is, it showed itself as an anabolic. However, the 800 mg dose also increases the concentration of cortisol, which has a catabolic effect.
The more often you swallow large portions of caffeine, the more likely you are to feel its negative effects. In addition, with frequent use, some of the caffeine benefits are lost, a kind of tolerance is developed. To avoid this, caffeine is taken periodically. This makes sense if caffeine is drunk for the release of adrenaline, and regular breaks in drinking coffee, tea and energy drinks are necessary for the synthesis of dopamine. But if caffeine is hoped to reduce the risk of developing Parkinson’s disease or type 2 diabetes, it must be consumed regularly, and it is better not to swallow powders, but to drink tea and coffee.
