What Is the Safe Amount of Caffeine Per Day?

Caffeine is one of the most prominent natural stimulants found in various beverages and foods, such as coffee, tea, chocolate, and energy drinks. It's also one of the most widely consumed stimulants worldwide.

In this Prifaco blog article, we'll outline the safe daily caffeine intake for different individuals based on their health condition, as well as provide important information on how to deal with caffeine overdose. If you're interested, read on until the end!


Factors affecting the determination of the safe amount of caffeine

The amount of caffeine that suits you depends on several factors, including:

  • Your weight.
  • Your age.
  • Your overall health.
  • Genetics.
  • Medications you are taking.
  • Your sensitivity to caffeine.

For example, it is common for older individuals and those who are overweight to have lower sensitivity to caffeine compared to younger individuals and those who are underweight. Additionally, women may have a lower tolerance for caffeine due to hormonal changes.

Therefore, it is advisable to start with a small dose of caffeine and gradually increase it until you find the ideal amount that suits you.

Pregnant women and individuals with certain medical conditions should limit their caffeine intake, as we will explain in the following paragraphs, to avoid any negative effects on their health.


Safe amount of caffeine per day for healthy adults

According to the U.S. Food and Drug Administration (FDA), most healthy adults can consume up to 400 mg of caffeine per day without experiencing any harmful effects. However, as mentioned earlier, it's important to note that caffeine sensitivity varies from person to person.

Some individuals may experience negative effects even with low doses of caffeine, so it's advisable to test the impact of caffeine on your body by starting with small amounts and gradually increasing them.


Safe amount of caffeine per day for pregnant and breastfeeding women

The safe amount of caffeine can vary based on medical and health recommendations, depending on individual circumstances. However, as a general guideline, it is advisable for pregnant and breastfeeding women not to exceed a daily caffeine intake of 200 mg.

Therefore, it's important to monitor your sources of caffeine to estimate the amount. It's also recommended to wait a few hours after consuming a caffeinated beverage or food before breastfeeding to allow the caffeine levels in the mother's bloodstream to decrease.

Caffeine safe limits for children

Children are often exposed to caffeine from various sources, including soda, coffee, energy drinks, and even tea. While there are no official guidelines for children's caffeine consumption, some experts suggest that a safe limit is less than 2.5 mg of caffeine per kilogram of the child's body weight daily.

In Canada, recommended daily caffeine limits are 45 mg for children aged 4 to 6 years and 85 mg for ages 10 to 12 years.


Caffeine side effects

Excessive caffeine consumption can lead to a variety of negative symptoms, including:

  • Muscle tension.
  • Anxiety.
  • Irregular heartbeats.
  • High blood pressure.
  • Sleep problems.
  • Headaches.


Recovering from caffeine overdose

There are several steps that can be used in the event of an overdose of caffeine, as follows:

1. Seek Urgent Medical Assistance

The first step should be to seek immediate medical care, as an overdose of caffeine can be life-threatening if left untreated.


2. Stay Hydrated

Consuming a large amount of caffeine can increase urination, leading to dehydration. It's important to drink a substantial amount of water throughout the day, up to 10 cups, to replenish lost fluids.


3. Practice Deep Breathing

When someone consumes more caffeine than their body can tolerate, it stimulates the sympathetic nervous system, increasing heart rate and blood pressure.

Deep breathing can help counteract this effect and reduce heart rate and blood pressure by activating the parasympathetic nervous system. It's worth mentioning that this technique should be repeated for several minutes until the symptoms subside.


4.  Avoid Caffeine the Next Day

It's advisable to steer clear of caffeine the day after consuming a large dose to allow the body to eliminate the previous amount and avoid the rapid onset of negative effects due to caffeine accumulation in the bloodstream.
