Keep reading to discover more about the side effects of consuming too much green tea.

HOW I STARTED MY RESEARCH ABOUT THIS TOPIC

Last month, a customer asked me this question.

Is drinking too much green tea bad for me?

Since I knew very well about caffeine from my earlier research and article I wrote, I told the customer about the disadvantage of caffeine during the call.

After that, I thought I should see if there are another effect of drinking too much green tea.

As I research more, I find out some negative effects.  I almost stopped writing about the article once as you know I promote healthy green tea and I am drinking green tea because it makes me feel better and healthy. But I thought it is important to write about this and being honest with you.

As a green tea lover, this article was really hard to write, but I wanted to be true to the facts and science. 

This article is not my favorite one as a result but gives you important information about green tea when drink excessively.

EXCESSIVE CAFFEINE INTAKE IS HARMFUL TO HEALTH

Green tea is a caffeinated beverage and has many health benefits. It almost helps in all body functions and keeps you active and fresh all day. The caffeine levels vary from green tea brands to brand or types. To check the exact amount of caffeine in a green tea product, you should look at the packaging and check before buying.

Many major brands of green tea include approximately 35 milligrams of caffeine per tea bag. The consumption of between 200 and 300 milligrams of caffeine per day is useful and beneficial for health. However, less caffeine intake may cause stronger side effects for sensitive people, and it is always advised to confirm the amount before drinking.

On the other side, as you know, excess of anything is harmful in every way for the human body, and green tea is no exception. Green tea has caffeine, and excess of it is harmful to health. When you consume tea in more doses than intended, then it can cause a health problem. Such issues include:

An increase in heart rate

Though caffeine is present in a moderate amount in tea but can help in many ways, such as lowering blood pressure. However, it is not good for people with some heart problems; it causes irregular heartbeat in some people due to some compounds and also interferes with blood pressure medication. If you are thinking of consuming green tea, then it is a wise decision to seek your doctor about your heart problems first and then make a decision.

An upset stomach

Green tea, if not taken with precaution, may cause stomach problems and would be harmful to health for those who already have stomach issues. It contains tannins that increase the level of acid in your stomach, and that may lead to digestive problems such as constipation, acid reflux, and nausea, etc. Moreover, if you brew it strong or take it on an empty stomach, then it will cause stomach irritation.

If you take it in excess amount, then caffeine present in tea produces laxative that stimulates the colon muscles, which in result contract and release more and causes upset stomach and diarrhea. The tea brewed with too hot water can worsen these problems, and it is advised to keep the water temperature between 160 to 180F.

 Also, to avoid most of these symptoms, takes green tea after one hour of a meal and in a small amount. Lastly, absolutely avoid it if you are already suffering from acid reflux disease because it will increase acidity.

Increase in anxiousness

The high level of caffeine in the blood leads to a jittery feeling in body parts and anxiousness. In one way, it helps with a mild anxiety issue, but excess consumption may lead to worsening the condition. It is advised that if you are prone to anxiousness, then it is wise to monitor your daily green tea intake. 

Restlessness

It can cause restlessness if you overdose the green tea because caffeine though present in a moderate amount, can still affect your nerves if taken in excess amount. To keep your nerves relax and active, you should keep your consumption mild.

Tremors

Tremors, some call it jittery or trembling, feeling on parts of your body, which is caused by taking caffeine in large amounts. It is another prominent side effect along with others and happens if you drink green tea more than the safe quantity.

Insomnia

The caffeine is known as a stimulant that activates your brain and nerves and keeps you on feet all day. It works the same evening green tea and keeps you up and active all day. However, if you drink too much or late in the day or at night, then it may lead to insomnia. If you already have sleeping problems, then avoid taking it late evening or at night, so your sleeping schedule does not disturb due to high caffeine in your blood.

Withdrawal symptoms

It is good to build up a routine about healthy habits and stick to it. However, if you are routinely drinking green tea and suddenly stops, then you may experience withdrawal symptoms. Such symptoms include irritability, drowsiness, and headaches, etc.

Too much green tea

Along with caffeine, green tea contains many other compounds that are not only beneficial for health but can cause harm to your health. Green tea has substances like antioxidants that control oxidant levels in the blood and are useful for health. If not taken properly or without consulting a doctor first, it may harm your health. Such problems caused by tea are explained below:

IMPAIRED IRON ABSORPTION DUE TO GREEN TEA

Green tea contains an antioxidant known as flavonoids that benefits human health in many ways. Food and tea that contain flavonoids when consumed help the body to absorb nonheme iron present in the blood and thus increase the iron level in blood. The nonheme iron is also present in plants like beans, vegetables, and fruit. However, if you drink tea right after the meal, then flavonoids will bond with iron resent in the meal, and these bonds body cannot absorb or use. 

It is advised not to drink green tea with a meal because it will lead to less absorption of iron from your food into the blood and result in iron deficiency. If you want to drink tea, then at least wait 45 minutes or an hour after eating a meal.

Moreover, squeeze a little lemon to your green tea because it will help in the prevention of the flavonoids binding to the iron in your diet. So, if you take green tea with a meal, then the best way is to squeeze a lemon into your cup and have the best health benefit.

THE NOT-SO-SWEET RESULTS OF DRINKING SWEET TEA

The best way to drink tea is self brewed with little sugar added. However, If you buy green tea in an already made bottle from a store or add a large amount of sugar or honey, then it is not healthy for your body. In this way, you are adding extra calories to your daily calorie intake, and that will lead you to gain extra weight.

Plain green tea from a teabag or other source is calorie-free and beneficial. However, bottled green tea is sweetened with an excess amount of sugar and can cause health problems such as obesity and diabetes.

DRINKING GREEN TEA DURING PREGNANCY COULD HARM YOUR BABY

Among many other ingredients, green tea also has tannies, which is not beneficial for pregnant women. Drinking green tea for more than three cups a day affects the baby’s growth and prevents the absorption of folic acid.

Folic acid is an important nutrient during pregnancy and is advised to increase its intake because it helps in protecting against birth defects. According to studies, folic acid supplementation lowers the risk by 70% of spina bifida and other neural conditions.

Lastly, if you are pregnant, then it is advised to limit your intake of green tea to a minimum or avoid it altogether. Fewer nutrients in the body lead to complications during delivery and may cause after effect.

COULD MY GREEN TEA CONSUMPTION CAUSE MEDICAL PROBLEMS?

Generally, green tea is beneficial for health, but, as stated earlier, the excess is always bad for health. Same way, drinking green tea too much will only worsen the already existed medical conditions. If you have issues like anxiety, diarrhea, and such, then it will increase the level and amount and will leave you sicker.

Moreover, people possessing medical conditions mentioned below should not consume green tea at the risk of making it worse. But if you like to drink, then consult your doctor before drinking it to make sure the small amount is suitable for your body. The health conditions include:

  • Bleeding disorders
  • Anemia
  • Glaucoma
  • Heart conditions
  • Bleeding disorders
  • Any liver condition
  • Anxiety
  • Diarrhea and other gastric disorders
  • Depression

To conclude, green tea has many health benefits but can also damage health if you overindulge and drink in excess quantity. Also, if you have a caffeine sensitivity, then cut down your intake and, most importantly, consult your doctor before continuing your consumption of green tea.
