How much caffeine is safe?

Most people can consume as much as 400 milligrams of caffeine a day without facing side effects. How much is 400 milligrams? In terms of coffee, it’s about four cups of brewed coffee. If you’re drinking energy drinks, it’s approximately one 16 ounce energy drink, two energy shots or ten cans of cola. Since it varies, you need to check the label to see how much each one contains. More dangerous than those drinks is straight caffeine, either in pill or liquid form. It only takes one teaspoon of powdered caffeine to equal the amount in 28 cups of coffee.

Some people shouldn’t consume even an average amount of caffeine.

If you have children, keep the caffeinated drinks away from them. Excessive caffeine can easily be consumed with very little intake. Pregnant or lactating women should cut caffeine intake in half, ingesting less than 200 mg a day. For people who are sensitive to the effects of caffeine, even a small intake can cause side effects.

The effects caffeine can vary.

Caffeine is a stimulant. When you drink something that contains caffeine or take caffeine powder or pills, it absorbs into the bloodstream and goes to the brain where it blocks the neurotransmitter adenosine. That causes an increase in dopamine and norepinephrine, which boosts the firing of neurons. For most people, a little caffeine can improve the functioning of some areas of the brain. It can also cause the body to burn more fat, plus improve athletic performance.

You may think caffeine is only contained in soft drinks, energy drinks and coffee, but chocolate also contains caffeine. Dark chocolate coated coffee beans contain 336 mg of caffeine for 28 pieces.

  • There are other health benefits from food and drink with caffeine. Coffee has nutrients that reduce the risk of diabetes, plus vitamins and minerals. Green and to a lesser extent black tea and dark chocolate also have health benefits.
  • Too much caffeine can cause heart palpitations, tachycardia, headaches, irritability, muscle tremors, frequent urination or loss of control, panic attacks and insomnia.
  • Caffeine is addictive and dizziness, nausea, brain fog and a headache may be part of the withdrawal. If you take an OTC pain reliever like ibuprofen, acetaminophen or aspirin, it helps relieve the pain, but extends the withdrawal time, since they contain caffeine, too.
  • In order to avoid the effects of too much caffeine, stay hydrated. Drinking more water can lower the risk of losing too much fluid from the increased urination.
