What Does Science Say About the Ideal Quantity?
According to the Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA), the safe caffeine intake for healthy adults is up to 400 mg per day, which is roughly four 240 ml cups of filtered coffee. This amount may vary depending on the type of coffee and preparation method.
Recent studies also suggest that consuming 3 to 5 cups of coffee per day may be associated with a lower risk of mortality from various diseases. However, it is important to remember that this amount may not be suitable for everyone.
Factors That Influence Coffee Consumption
The ideal amount of coffee can vary from person to person. Some factors influencing this dose include:
- Caffeine sensitivity: Some people metabolize caffeine quickly, while others may experience adverse effects with small amounts.
- Health conditions: Individuals with high blood pressure, anxiety, or gastrointestinal issues may need to moderate their intake.
- Pregnant and breastfeeding women: The recommendation for pregnant women is to limit caffeine intake to about 200 mg per day (equivalent to two cups of coffee).
- Medication use: Some drugs can interact with caffeine, enhancing or reducing its effects.
- Physical activity: People who exercise regularly may have a higher tolerance to caffeine and benefit from its stimulating effect.
- Circadian rhythm: The time of day when coffee is consumed can impact its efficiency and effects on sleep.
- Genetics: Some genetic variations can affect caffeine metabolism, making some people more sensitive to its effects than others.
- Type of coffee and preparation method: The caffeine content can vary depending on the coffee bean type, roast level, and brewing method.
Does Excessive Coffee Consumption Cause Harm?
While coffee has many benefits, excessive consumption can cause adverse effects, such as:
- Insomnia and sleep disturbances
- Increased blood pressure
- Anxiety and nervousness
- Gastrointestinal problems, such as acid reflux
- Dependence and withdrawal symptoms
- Headaches and palpitations in extreme cases
- Reduced iron absorption, potentially contributing to anemia

- Fatigue after the initial stimulating effect wears off
Additionally, excessive consumption can affect mental health, contributing to symptoms of stress and irritability. It is essential to find a balance to avoid these undesirable effects.
How to Find the Right Balance?
If you enjoy coffee and want to reap its benefits without harming your health, some tips can help:
- Avoid drinking coffee late in the day to prevent sleep disturbances.
