Green Tea Side Effects

No doubt it is one of the healthiest drinks today but like most of the drinks there are things that you will have to consider before grabbing the next cup of green tea. This article will shed light on some of the mild and serious concerns that green tea can cause. Check out side effects, problems of Green tea –

Effect of Caffeine

Green tea is considered to possess the lowest rate of caffeine when compared to normal coffees and teas. However it still involves caffeine which can lead to restlessness, anxiety, increased heart rate, elevated blood pressure, palpitations and irritability when consumed in excess quantities. People who are sensible to caffeine are more prone to such effects. You can prevent this by consuming better quality Green teas that contain more Theanine which will calm your brain against the effects of caffeine. You can even consider drinking decaffeinated Green tea as an alternative.

Nausea and stomach upset

Tannins are a key ingredient present in Green tea that causes the stomach to produce more acid. Mostly people who have a history of peptic ulcer or acid reflux problems will generally suffer from a stomach upset or nausea. It is strongly recommended that you do not consume Green tea during diarrhoea as Tannins will just worsen the situation further more. The best way to tackle such situations would be consumed Green tea after a meal and not on an empty stomach.

Iron deficiency

Tannins come into play even here and in a research it was found that tannins prevent the blood from absorbing essential nutrients such as iron which results in deficiency. It was found that excessive consumption of Green tea resulted in 25% less iron in the body and the best way to tackle them would be to add lemon to the Green tea or consumption of Green tea between meals.

Pregnancy issues

Doctors strictly advice pregnant ladies not to consume any form of caffeine during the early stages of their pregnancy as it might result in a neural birth defect and since Green tea too contains caffeine it might produce side effects similar to a normal coffee or tea.

Medication problems

Green tea and medications are not quite compatible. It causes reactions similar to a normal tea when it comes in contact with some medications. Just to be on the safer side make sure you do not intake any caffeine or Green tea for two hours after you have consumed the medicine. However the advice of a trusted doctor is always recommended for such complications.


Well undoubtedly the worst side effect of Green tea is Osteoporosis. In some case studies it was found that Green tea increases the amount of calcium that is flushed out from the body through urine. However this mostly occurs when a person consumes around 400 mg of caffeine or more per day i.e. around 4 to 5 cups of Green tea per day. this can be tackled by consuming adequate calcium supplements.

On the whole the benefit of consuming Green tea is more than the side effects that it brings and in most of the cases it was found that people who consume Green tea inadequately or in excess quantities are more likely to develop such conditions caused by caffeine. Most of the Physicians advice drinking around 2 to 3 cups of Green tea per day but exceeding that margin may lead to undesirable effects and harmful problems.

These are some of the most common Green Tea side effects brought to our lives unknowingly.
