How Many Caffeine Can I Intake Per Day?

June 2, 2022
Caffeine is a stimulant that is found in coffee, tea, and other beverages. The caffeine content can be affected by the quality of the beans, water used to brew it, and more. The quality of the beans is one factor that can influence caffeine quality. Coffee beans are grown in different areas which may have different climates and growing conditions. This affects the type of bean used to make the coffee which may result in varying levels of caffeine content.

Coffee is an indispensable drink for many people every day. A cup of coffee in the morning is definitely an artifact to wake up the spirit of the whole day! However, although coffee is fragrant and refreshing, drinking too much can cause problems such as rapid heart rate. So how much coffee should you drink every day? How much caffeine is there in different brands of coffee?

It is important to know how many caffeine you can take before it becomes a problem. For healthy people, the answer is anywhere from 400-600 mg per day. For those with chronic health problems, it is recommended to stay below 300 mg of caffeine a day. The best way to determine how many caffeine you can take in a day is by looking at your body mass index and heart rate. If your body mass index (BMI) is greater than 30, then you should not exceed 300 mg of caffeine per day. If your BMI falls between 25-30, then you should not exceed 400 mg of caffeine per day. . If your BMI is between 18.5-25, then you should not exceed 500 mg of caffeine per day. And if your BMI falls below 18.5, then you should not exceed 600 mg of caffeine per day.

For Pregnant women: If you are already pregnant, the American College of Obstetricians and Gynecologists recommends that pregnant women limit their caffeine intake to 200 mg per day. That's about two 6-ounce cups of coffee. (However, the specific coffee intake varies from person to person, please discuss with your gynecologist)

For Children: According to the Mayo Clinic, children and adolescents ages 12-18 should limit their intake to 100 mg per day. The American Academy of Pediatrics (AAP) recommends that children under the age of 12 should not consume caffeine.

There are a number of factors that can influence the quality of caffeine. These factors include the type of beans, the time it takes to extract caffeine from them, and how they are processed.

There is a trade-off between quality and price in this market. Beans that have been grown in high altitude areas tend to offer better quality but are also more expensive than those grown at lower altitude areas.

One of the factors that can influence caffeine quality is the type of beans. The caffeine content in coffee is a result of how much caffeine is extracted from the beans during roasting.Some factors that can influence caffeine quality are:- The type of beans (e.g., Arabica vs Robusta)- The roast level (e.g., light, medium, dark)- The grind level (e.g., coarse, fine)- How long it takes to brew- How you brew your coffee (e.g., short or long brewing time, filter vs. espresso)

- The amount of coffee you brew per cup (e.g., the more coffee you brew, the stronger it is)

- The brewing time

Brewed Coffee

Brewing in the US is the most common way to make coffee. Brewed coffee is made by pouring hot or boiling water over ground coffee beans, usually contained in a filter.A cup of brewed coffee (8 ounces) contains about 70-140 mg of caffeine, or an average of about 95 mg.


Espresso is made by passing a small amount of hot water or steam through finely ground coffee beans.While espresso has more caffeine per volume than regular coffee, it's usually less caffeine per serving because espresso tends to be smaller in serving size. A cup of espresso is generally about 30-50 milliliters (1-1.75 ounces) and contains about 63 milligrams of caffeine. So, two cups of espresso have about 125 mg of caffeine.Many coffee beverages are made from espresso mixed with different types of milk, including lattes, cappuccinnos, macchiatos, and americanos. Since milk does not contain any additional caffeine, these beverages contain the same amount of caffeine as drinking espresso straight. A single (small) cup contains an average of about 63 mg of caffeine, and a double (large) cup contains about 125 mg.

Instant Coffee

Instant coffee is made from brewed coffee that has been freeze-dried or spray-dried. It is usually bulky, dry and can be dissolved in water. To prepare instant coffee, simply mix a teaspoon or two of dry coffee with hot water. Instant coffee usually contains less caffeine than regular coffee, with about 30-90 mg in one cup.

Decaf Coffee

Decaf coffee is not completely caffeine-free. It may contain varying amounts of caffeine, ranging from 0-7 mg per cup, with an average cup containing 3 mg. However, some varieties may contain more caffeine, depending on the type of coffee, the method of decaffeination, and the size of the cup.
