Aside from water, black tea is one of the most consumed beverage in the world.

It comes from the Camellia sinensis plant and is often blended with other plants for different flavors, such as Earl Grey, English breakfast or chai.



Here are 10 health benefits of black tea, all supported by science.

1. Has Antioxidant Properties

Antioxidants are known to provide a host of health benefits.

Consuming them can help remove free radicals and decrease cell damage in the body. This ultimately may help decrease the risk of chronic disease.

Polyphenols are a type of antioxidant found in certain foods and beverages, including black tea.

Groups of polyphenols, including catechins, theaflavins and thearubigins, are the main sources of antioxidants in black tea and may promote overall health.

In fact, one study in rats examined the role of theaflavins in black tea and the risk of diabetes, obesity and elevated cholesterol. Results showed that theaflavins reduced cholesterol and blood sugar levels.

Another study examined the role of catechins from green tea extract on body weight. It found that those who consumed a bottle containing 690 mg of catechins from tea on a daily basis for 12 weeks showed a decrease in body fat.

While many supplements contain antioxidants, the best way to consume them is through food and beverages. In fact, some research has found that taking antioxidants in supplement form may harm your health.

2. May Boost Heart Health

Black tea contains another group of antioxidants called flavonoids, which benefit heart health.

Along with good quality tea, flavonoids can be found in vegetables, fruits, red wine and dark chocolate.


One randomized controlled study found that drinking black tea for 12 weeks significantly decreased triglyceride values by 36%, reduced blood sugar levels by 18% and lowered the LDL/HDL plasma ratio by 17%.

Another study found that those who drank three cups of black tea per day had an 11% reduced risk of developing heart disease.

Adding black tea to your daily routine is an easy way to incorporate antioxidants into your diet and potentially reduce your risk of future health complications.

3. May Lower “Bad” LDL Cholesterol

The body contains two lipoproteins that transport cholesterol throughout the body.

One is low-density lipoprotein (LDL), and the other is high-density lipoprotein (HDL).

LDL is considered the “bad” lipoprotein because it transports cholesterol to cells throughout the body. Meanwhile, HDL is considered the “good” lipoprotein because it transports cholesterol away from your cells and to the liver to be excreted.

When there is too much LDL in the body, it can build up in the arteries and cause waxy deposits called plaques. This can lead to problems like heart failure or stroke.

Fortunately, some studies have found that consuming tea may help reduce LDL cholesterol.

One randomized study found that drinking five servings of black tea per day reduced LDL cholesterol by 11% in individuals with slightly or mildly elevated cholesterol levels.

Another randomized three-month study in 47 individuals compared the effects of traditional Chinese black tea extract and a placebo on LDL levels.

Results showed a significant decrease in LDL levels in those who drank black tea, compared to the placebo, without any undesirable side effects. Researchers concluded that black tea helped improve cholesterol levels in individuals at risk for heart disease or obesity.

4. May Improve Gut Health

Studies have found that the type of bacteria in your gut may play a significant role in your health.

That’s because the gut contains trillions of bacteria, as well as 70–80% of your immune system.

While some of the bacteria in your gut is beneficial for your health, some are not.

In fact, some studies have suggested that the type of bacteria in your gut may play an important role in reducing the risk of certain health conditions, such as inflammatory bowel disease, type 2 diabetes, cardiovascular disease, obesity and even cancer.

The polyphenols found in black tea may help maintain a healthy gut by promoting the growth of good bacteria and inhibiting the growth of bad bacteria, such as Salmonella.

In addition, black tea contains antimicrobial properties that kill off harmful substances and improve gut bacteria and immunity by helping repair the lining of the digestive tract.

However, further research is needed before a strong conclusion can be made regarding the role of black tea and immune function.
