Green Tea Side Effects You Need to Know About

Green tea is a superdrink — there’s no doubt about it.

Originating from China, this healthy beverage can be taken for a variety of purposes such as reducing stress, calming the mind, improving cognitive functioning, alleviating joint pain and swelling, shedding off excess pounds and fending off all sorts of medical conditions, many of which can be very serious, such as diabetes, heart disease and cancer.

But just because it’s regarded as a healthy drink doesn’t mean that you should have lots of it!

Especially if you are extremely sensitive to caffeine, having several cups of green tea per day can cause some side effects to come into being although some of them are quite rare, experts say.

Needless to say, too much of something — including one that’s super beneficial — is bad for you!

Keep on reading to know some of the unfavorable side effects that you may encounter if you consume excessive amounts of green tea. Don’t forget to share this article on your various social media sites afterwards so that your health-conscious family members and friends may also get acquainted with the said potential side effects.


It’s true that the intake of green tea is recommended for people who have lots of anxious thoughts. That’s because certain compounds in it is scientifically proven to help calm the mind.

Since green tea has caffeine in it, the consumption of multiple cups of it a day or something with a really strong brew can leave a person with anxiety even more anxious. Its caffeine content is a stimulant, and that’s why it can cause all kinds of symptoms that an anxious person finds terrifying — heart palpitations, lightheadedness, chest tightness, etc.


Having lots of green tea in a short period of time can cause the consumer to rush to the bathroom constantly. It’s for the fact that diarrhea may strike if this healthy beverage is consumed excessively.

It’s not just the nervous system that can get excited by caffeine in green tea, but also the digestive tract. What’s more, it has laxative properties that can make the stools loose and always coming. Naturally, excitation of the digestive tract can cause abdominal pain to be experienced, too, by the individual who can’t control his or her green tea intake.


Having a cup of green tea can help a person get a good night’s sleep especially if it’s taken after a long and tiring day and lots and lots of stress hormones are coursing through his or her blood vessels. However, someone who is sensitive to caffeine should not follow suit as he or she may fail to have a trip to dreamland.

Again, it has something to do with the fact that the caffeine content of green tea can stimulate the nervous system. As a general rule of thumb, a caffeine-sensitive individual should stay away from green tea 6 hours before bedtime.


Put simply, anemia is a blood condition in which there’s insufficiency in red blood cells or RBCs, which are blood components that carry oxygen molecules. This is a bad thing because it can deprive the organs and muscles of oxygen, thus causing fatigue, heart palpitations, shortness of breath and many others.

Unfortunately, those who are suffering from anemia or at high risk of it are discouraged from taking green tea as some of its antioxidant content can hinder absorption of iron, a mineral needed for the production of RBCs.


It’s not just iron that some of the compounds in green tea can inhibit the proper absorption of, but also calcium. Everyone knows that calcium is very important for keeping the bones strong.

This is the reason why excessive consumption of green tea is not a good idea especially for people who seem to be sensitive to this healthy drink. Individuals who are at high risk of developing the bone disease called osteoporosis — such as the elderly and menopausal women — should think twice before having several cups of green tea a day.
