Green tea is known as one of the healthiest beverages in the world, with a wide range of proven benefits. However, some side effects are possible and should be taken into consideration when drinking green tea on a regular basis.

Green tea has a number of benefits and side effects. It is important to know who should not drink green tea, so that it does not do any harm.

Benefits and Side Effects Of Green Tea

Green tea is one of the world’s healthiest drinks. It is high in a variety of minerals and antioxidants, all of which offer several health advantages. So, in this post, we’ll learn about some of green tea’s established health advantages and adverse effects.

Green Tea’s Health Benefits

Green tea is good for your brain.


Green tea has a number of active ingredients that may help you boost your brain performance. Caffeine and l-theanine, an amino acid that may penetrate the blood-brain barrier, are the most crucial.

Green tea consumption has been demonstrated to lessen psychopathological symptoms such as anxiety and depression in studies. It also improves a person’s memory and raises their attention. L-theanine has also been shown to boost alpha-wave generation in the brain in studies. Caffeine and l-theanine have synergistic effects, which means they boost brain function by working together.

Furthermore, research have shown that green tea may help to lessen the risk of degenerative illnesses including Alzheimer’s and Parkinson’s. Green tea’s antioxidants and anti-inflammatory chemicals are likely to be responsible for this impact.

Green tea has been shown to lower the risk of a variety of malignancies.


Cancer is caused by uncontrolled cell proliferation. It is one of the major causes of death in the globe. Free radical oxidative damage is one of the key causes that lead to cancer. Within our cells, these free radicals are constantly forming. Cells, on the other hand, have the potential to produce antioxidants, which may neutralize free radicals. Green tea also has a lot of antioxidants and anti-inflammatory compounds. Green tea drinkers have been demonstrated to have a lower chance of acquiring malignancies such as breast cancer, prostate cancer, and colon cancer, according to research. To gain the best health advantages from green tea, avoid adding milk since milk might lower the antioxidant activity.

Green tea may aid in the prevention of type 2 diabetes.


Diabetes is a global health issue that is becoming more prevalent. Elevated blood sugar levels are a symptom of type 2 diabetes, which may be caused by insulin resistance or an inability to make insulin. Green tea has been shown in studies to enhance insulin sensitivity and lower blood sugar levels.

Green tea may assist in the prevention of cardiovascular disease.


The primary causes of mortality are cardiovascular disorders, such as heart disease and stroke. Green tea has been shown in trials to improve some of the primary risk factors for these illnesses, such as total cholesterol and LDL cholesterol levels. Green tea also boosts the blood’s antioxidant capacity, which protects LDL particles from oxidation, which is one of the factors that leads to heart disease. Furthermore, green tea may help to reduce blood pressure. Green tea use decreases the risk of mortality from cardiovascular disease by roughly 30%, according to evidence-based research, which is fairly astonishing.

Green tea boosts fat oxidation.


Green tea contains caffeine, a stimulant that has been demonstrated to help in fat burning and workout performance. Various studies have shown that a wide spectrum of antioxidants may help burn fat and enhance metabolism, both of which are important for weight loss. Furthermore, green tea aids in increasing metabolic rate, fat oxidation, and even insulin action. It is crucial to remember, however, that these effects may range from person to person. As a result, it is impossible to state that drinking green tea alone will help you lose weight in all cases; this does not always happen.

Green tea has been shown to help with foul breath.


Test tube studies reveal that catechins may restrict the development of bacteria, possibly decreasing the risk of infections streptococcus mutants is a prevalent bacterium in the mouth that promotes plaque production and is a primary contributor to cavities and tooth decay. Green tea catechins have been shown in studies to suppress the development of oral germs and decrease foul breath.

Green tea is good for your skin.


Green tea also includes various vitamins, including vitamin C, vitamin B2, vitamin E, and folic acid, in addition to the chemicals previously mentioned. Vitamin C is necessary for collagen formation, and all of these vitamins are necessary for good skin.

Green Tea’s Surprising Side Effects


They say that being green is the way to go, and we agree. Green tea is usually thought to be safe to take by adults. There are a few negative consequences to be aware of.

We’ll look at six of the disadvantages of drinking green tea today.



Green tea includes caffeine, which may induce headaches in certain people. Migraine sufferers should drink green tea on a regular basis. However, if you suffer from frequent headaches, you should avoid drinking green tea every day. If you have a caffeine sensitivity, green tea should be avoided.

Stomach Issues:


Green tea includes tannins, which might cause your stomach acid to rise. Constipation, acid outflow, and nausea are all symptoms of too much acid in the stomach. If the water is overly hot, the negative effects of green tea might be increased. Green tea should be brewed using water that is between 160 and 180 degrees Fahrenheit.

Rare instances of bleeding problems include:


Green tea has the potential to cause bleeding problems. Green tea contains chemicals that reduce fibrinogen, a protein that assists in blood clotting. Green tea also inhibits the oxidation of fatty acids, which might result in a thinner blood consistency. If you have a blood clotting condition, stay away from green tea.



Green tea in excess may cause nausea and vomiting, so limit yourself to no more than 4 cups per day. If you’re a tea aficionado.

Liver Illness:


Green tea supplements and excessive green tea use might cause liver damage and illness. This, according to experts, is due to a buildup of caffeine, which may damage the liver. Prevent drinking more than four to five cups of green tea every day to avoid the negative effects.

Pregnancy and child risk:


Tea catechins, tannins, and caffeine have all been associated to increased stress during pregnancy, but doctors believe that 20 in modest quantities, no more than 2 cups per day, is safe during pregnancy and nursing.

The majority of the negative effects of green tea may be prevented by drinking it in moderation. If someone suffers green tea side effects, it’s because they drank too much of it, had a low-quality tea, or are caffeine sensitive. Green tea should never be consumed on an empty stomach.
