Side Effects of The Green Tea and Who Must Avoid It!

To have a perfect start of the morning I always prefer to have a cup of green tea. A new day, a positive thought, a fresh mind asks for this cup of life. This cup of energy is like a fuel to the engine of my body which gives a kick to start the day. I used to take it thrice in a day as in the morning, in the afternoon and after returning back from work. This evening dose rejuvenates me and helps me to leave all the tiredness.




As we know that people of this era are very much health conscious. They choose their food by their nutritional values. In that way, green tea is something that is very rich in its qualities. It is a good source of antioxidants and alkaloids. It contains various vitamins like A, D, C, B, B5, H, and K. The most important component of it is Epigallocatechin gallate (EGCG), which helps to reduce inflammation, aid weight loss and helps to prevent heart and brain diseases. Moreover, it is a calorie-free beverage that can be consumed up to five to six cups a day. Nowadays different tea brands are providing exciting flavors of green tea, like Jasmine green tea, Moroccan mint green tea, Honey Lemon and many more. So now it is not just a simple tea but a treat to oneself.

Besides its goodness, it has some side effects also that will make a person think before taking a sip of it.

Here are certain health conditions when it should be avoided  -

Iron deficiency and anemia 

Catechin present in green tea decreases the absorption of iron. So persons having a low level of hemoglobin in blood should avoid it.

Pregnant or nursing women 

Green tea contains caffeine which pregnant women are urged to drink in moderation. It should be avoided by nursing mothers also as caffeine passes into breast milk and can affect the infant.

Insomnia, Nervousness, and Anxiety

The caffeine content in green tea increases alertness and that can affect sleep. That is why it is generally advised to not take it before sleep.

Irregular Heartbeat

Caffeine in green tea might cause irregular heartbeat. It can raise blood pressure. So it should be avoided by people who have high blood pressure problems.



Nausea or Upset Stomach

The tannins present in green tea increases stomach acidity, which can lead to problems like stomach aches, nausea, etc.

High Blood Pressure

Compounds in green tea decrease the level of fibrinogen, a protein that helps in the blood clot. It also prevents the oxidation of fatty acids, which can lead to thinner blood consistency.

So, like all other elements of earth green tea has several good effects and side effects. Green tea is considered as a safe beverage by the FDA when consumed in moderation. Most of these side effects are only due to the caffeine content and only occur when the consumption amount is high, Which may include some or all of these symptoms:


  1. Mild to serious headaches
  2. Nervousness
  3. Diarrhea
  4. Sleep problems
  5. Vomiting
  6. Irregular heartbeat
  7. Tremor
  8. Ringing in the ears
  9. Heartburn
  10. Dizziness
  11. Irritability etc.

So, one should be wise enough to decide what amount of green tea should be taken under which health conditions.
