Caffeine Sensitivity Guide

Caffeine, a stimulant, is most commonly found in coffee, tea, and soda. Caffeine has a positive effect on most people. It can give them an extra boost of energy or improve their focus. Nevertheless, some people can be more sensitive to caffeine’s effects on the nervous system. This is called caffeine sensitivity.

What is Caffeine SensitivityCaffeine sensitivity stems from a person’s ability synthesize caffeine and metabolize it in the body. The genetic makeup of an individual is often a factor in determining sensitivity. Genetics can cause some people to be more sensitive than others to caffeine’s stimulant effects.

The liver enzyme CYP1A2 is responsible for metabolizing caffeine. CYP1A2 is the gene that controls how well this enzyme can be produced. This gene has small differences that can affect the way caffeine is metabolized.


Caffeine Sensitivity Side Effects
People with normal caffeine reactivity can consume 200-400mg per day without experiencing any adverse effects.

Even with a standard serving, those with caffeine sensitivity can experience the symptoms of an overdose. These symptoms include:

  • Restlessness or jitters are both examples of jitters.
  • Anxiety without a known cause
  • Excessive talking.
  • Inability to concentrate.
  • Nausea.
  • Heart palpitations.
  • Elevated heart rate and blood pressure.
  • Insomnia.
  • Vomiting.
  • Sweating.
  • More.

Caffeine sensitivity may be at work if you feel these symptoms following a cup of coffee. Caffeine may be safe for many, but for those who are sensitive to it, it can cause serious health problems such as heart issues and even cardiac arrest. Caffeine sensitivity is a reason why those who are sensitive to it should avoid caffeine.

There are many delicious decaf teas and coffees available. For those who want to increase their energy levels without caffeine, they can turn to regular exercise, meditation or a better diet.

Some people cannot drink caffeinated drinks. Some people are more sensitive to caffeine’s stimulant effects due to genetic differences. You should avoid caffeine if you are experiencing negative side effects.
