Is 300 mg of caffeine a day bad? Consuming up to 400mg of caffeine per day is safe for most healthy adults. That 400 mg constitutes to about 4 cups of brewed coffee or 10 cans of coca cola or two energy shots. Now that sounds like a lot of caffeine and most people don’t need that much to stay alert unless they are not getting enough sleep. Or maybe they are not getting enough carbohydrates in the foods they ate.
One of the worst things in the world is to live off caffeine every single day because you don’t get enough sleep daily. The result of this is you will need caffeine daily to stay awake. The problem with that is you will feel the symptoms of having too much caffeine such as nervousness, anxiety, jittery, fast heartbeat, irritability, etc.
Pregnant women and children should limit their caffeine intake to 200mg or less.
Studies have shown that extremely high caffeine doses of 1000mg or more per day has caused nervousness, anxiety, jitteriness, and other unhealthy symptoms. It is unhealthy and dangerous to consume that much caffeine daily.
Everybody reacts to caffeine differently as some people have more of a higher tolerance than others. So, if you feel any of those symptoms such as feeling jittery or nervousness then you may need to cut down your caffeine intake.
Studies have shown that excessive caffeine can lead to a high amount of insomnia which would affect your ability to fall asleep. And studies have shown it will affect your quality of sleep too. It is important to reduce your caffeine consumption around the afternoon time to avoid sleeping issues.
Caffeine has been shown to raise blood pressure levels in healthy adults who exercise. And people who already have elevated high blood pressure levels.
Large doses of caffeine can also increase your heartrate, heartbeat, and rhythm in people. This will cause your heart to beat faster than the average rate.
There was a case study where a woman consumed a massive dose of caffeine powder and tablets in an attempted suicide. Their side effects were a very rapid heart rate, kidney failure and other serious related health issues.
