What is Caffeine?

Caffeine is a stimulant that acts on the central nervous system. It occurs naturally in tea, coffee, cacao, and other plants. Or it can be prepared synthetically and added to products like caffeine pills, caffeinated sodas, and energy drinks.

Caffeine Health Benefits

Caffeine offers numerous health benefits when consumed appropriately, especially when you drink coffee. According to the Harvard School of Public Health, coffee has many other nutrients that work symbiotically with caffeine to promote overall health.

Consumption of 3 to 5 standard cups of coffee daily has been consistently associated with a reduced risk of several chronic diseases.

Caffeine’s main impact is on your brain. It boosts energy by blocking the neurotransmitter adenosine, which is responsible for making you feel sleepy. Studies have also shown that it can improve focus and mood and protect against brain diseases like Alzheimer’s and Parkinson’s (1).

Outside the brain, caffeine has been shown to boost metabolism, protect against heart disease and diabetes, improve athletic performance, and reduce the risk of liver damage, among other possible benefits. Talk about a miracle drug – in the right dose, that is.

Caffeine Overdose

Caffeine overdose to the point of illness or death is very rare. If you exceed our caffeine counter’s recommended dose, you might notice mildly unpleasant symptoms like anxiety, restlessness, and trouble sleeping. Go further over the limit, and you could suffer from migraines, an irregular heartbeat, or increased blood pressure. At very high doses, vomiting, abdominal pain, and seizures are possible.

Death By Caffeine

Studies have shown that caffeine blood levels need to reach about 180 mg/L to run the risk of death (2). That’s equivalent to drinking about 30 cups of coffee in a short time frame!

Caffeine overdose is usually the result of caffeine pills or amped-up energy drinks.

For example, there’s the case of 29-year-old personal trainer Tom Mansfield, who died after accidentally consuming caffeine powder equivalent to 200 cups of coffee (3).

Final Thoughts

Knowing your daily caffeine limit and the amount of coffee it takes to get there is essential, and this caffeine calculator makes it easy. Caffeine is a powerful force for good in your body when consumed correctly, but take too much, and you’ll experience jittery discomfort.

If you found this calculator useful, share it with your coffee and tea-loving friends to reap the health benefits of proper caffeine consumption together. 

FAQs


What is the pregnancy caffeine limit?

The pregnancy caffeine limit is 200 mg daily, about half the standard guideline. In the past, pregnant women were advised to avoid caffeine altogether because it can cross the placenta. But more recent research has shown that moderate amounts are safe.


How long does it take for caffeine to wear off?

It takes up to 10 hours for caffeine to wear off – i.e., completely clear your bloodstream. However, in only six hours, 50% of the caffeine consumed will be metabolized, at which point only those sensitive to caffeine will still feel its effects.


What coffee style has the most caffeine?

The coffee style with the most caffeine is espresso, which has 60 – 80 mg per ounce. However, espresso is typically consumed in small volumes, no more than 3 ounces at a time. 16-ounce drip coffee or cold brew can easily have more caffeine than a double shot.
