Caffeine is a natural substance that acts as a central nervous system stimulant. It is found in more than 60 plants, including coffee beans, tea leaves, cocoa beans and kola nuts. Although many people consume it on a daily basis, few know exactly how much they are ingesting depending on the type of beverage.
We are going to analyze and compare the caffeine content in five very common beverages: regular coffee, decaffeinated coffee, Coca-Cola, Red Bull and Monster.
1. Regular coffee (240 ml cup).
Estimated caffeine: 80-100 mg.
Coffee is the best known source of caffeine. Its content varies according to the type of bean (arabica or robusta), the preparation method (filter, espresso, French press, capsule), the roasting and the extraction time.
- An average cup of filtered coffee usually contains between 80 and 100 mg of caffeine.
Coffee provides a quick energy boost, improves alertness and can promote concentration. However, excessive consumption can cause nervousness, insomnia or palpitations.
☕ 2. Decaffeinated coffee (240 ml cup).
Estimated caffeine: 2-7 mg.
Contrary to what many believe, decaffeinated coffee is not caffeine-free. In general, between 97% and 99% of its content is removed through different processes (water, solvents, CO₂). The result is a very low caffeine beverage, but not completely free of caffeine.
It is ideal for those who are sensitive to this stimulant or want to avoid it in the afternoon or evening, without giving up the taste of coffee.
🥤 3. Coca-Cola (330 ml can).
Estimated caffeine: 32 mg.
Coca-Cola contains caffeine in a low proportion compared to coffee or energy drinks. It is enough to have a mild stimulant effect, although many people are not aware that they are consuming it.
In comparison, Coke Zero and Diet Coke also have caffeine, but slightly above (34-46 mg, depending on the country and formula). Other cola brands may vary their content.
⚡ 4. Red Bull (250 ml can).
Estimated caffeine: 80 mg.
Red Bull has a caffeine concentration similar to a normal cup of coffee, but with sugar and other ingredients such as taurine or B vitamins. Its stimulant effect is strong, especially in those who are not used to caffeine.
This makes the effect fast and noticeable, although of short duration. Its use has become popular among students, athletes and people who work night shifts. However, it is not recommended to consume it in excess or to combine it with alcohol.
Monster Energy (500 ml can).
Estimated caffeine: 160 mg.
Monster is one of the most caffeinated energy drinks on the market. A single can can contain as much as two cups of regular coffee, plus large amounts of sugar and other stimulants.
Its effect can last several hours and be intense, especially for those who are not accustomed to caffeine. In adolescents and people with anxiety or heart problems, its consumption should be limited or avoided.
So what has the most caffeine is: Can of Monster>Cup of regular coffee>Can of Redbull>Can of Coke>Cup of Decaf.
How much caffeine is safe per day?
Leading health authorities agree that moderate caffeine consumption is safe for most adults. The general recommendation is:
- Up to 400 mg daily (equivalent to 4-5 cups of coffee or 2 cans of Monster).
- For pregnant women: maximum 200 mg per day.
- In adolescents: no more than 100 mg per day.
Side effects of excessive caffeine may include insomnia, tachycardia, irritability, anxiety, heartburn or tremors.
💡 Other common sources of caffeine.

- Dark chocolate (10-30 mg per serving) (many people do not know this).
