3. Green Tea reduces the Absorption of iron from food

Your morning delicacy may turn into a nightmare as green tea reduces the absorption of iron from food and leads to iron deficiency (Fan, 2016). As far as the 2015 Dutch dietary guidelines are concerned, a person is recommended not to drink more than three cups of tea daily (Fan, 2016).

4. Green Tea slows down blood clotting

On an average, people drink 2-3 cups of green tea a day. Anything higher may slow down blood clotting since it contains vitamin-K (Punnose, 2015). High dose of vitamin K increases the length of time a clot takes to form over an injury (Punnose, 2015).

In case, you have a history of blood clots then you should discontinue taking any blood-thinning drug such as warfarin if you are also having green tea in your diet routine.

5. Green tea leads to stomach upset

As mentioned above, green tea leaves contain 3% caffeine and drinking it in excess of three cups a day may urge you to hit the washroom quite often. A higher dose of caffeine intake is associated with increased risk of diarrhea and Irritable bowel syndrome (IBS).

After going through the above green tea side-effects, a question must be popping out of your mind whether green tea is good for health or not? We must not forget that anything in excess can harm our body; therefore, it is necessary to control our craving for something we love rather than eliminating it out of our daily routine.
