Caffeine can give you that needed boost, but you can easily go overboard with it. According to registered dietitian Beth Czerwony, RD, it is a stimulant that affects your body in multiple ways.

Czerwony believes that it is best to weigh the risks and benefits but before that, let's discuss how much caffeine is too much caffeine.

How Much Caffeine Should You Ingest Per Day?


It's dependent on who you are. People who should avoid caffeine include pregnant women, kids, people on anti‐anxiety medication, and those with high blood pressure or heart disease.

If you're none of that and are healthy as a buck, then it's best to take caffeine in respectable quantities. Here are the rules.

Healthy adults should avoid consuming more than 400 milligrams (mg) of caffeine daily. That's about four 8-ounce cups of brewed coffee or ten cans of cola. Teenagers need to limit their caffeine intake to less than 100 mg per day, i.e., one 8-ounce cup of coffee or about two cans of cola.

What Happens When You Take Too Much Caffeine?


Caffeine can be a great help for you when you're trying to get through the day, but what happens when you go too far? Side effects appear, and they look like these:

1. Insomnia: people who have trouble sleeping teach for coffee to keep them active the next morning, but what they don't know is that it can keep them up at night, which means they'll have to repeat the notion the following morning. To avoid this, avoid caffeine in the afternoon and evening.


2. Anxiety: according to Czerwony, caffeine excites the central nervous system, and it can make some feel anxious and irritable. Reducing caffeine intake can help avoid this.

3. Heart palpitations: they are made worse by excess caffeine and can be quite alarming even though they won't kill you.

4. Dehydration: Caffeine is a diuretic which means you pee more when you drink it. Make sure you don't forget to take a lot of water between sips to avoid getting dehydrated.


5. High blood pressure: caffeine causes a mild increase in heart rate and blood pressure, which could spell doom for someone with the affliction.

Heartburn and stomach ache: caffeine can agitate stomach acids and trigger uncomfortable heartburn. Too much caffeine will cause stomach issues, so remember to cut back sometimes.


Caffeine is not a terrible product, but like many other things humans take, too much of it can constitute a problem, including addiction. If you find yourself addicted, it is best to cut back gradually to avoid or lessen the withdrawal symptoms. It will not be easy but rest assured it is a great decision.
