Black Tea vs. Green Tea~ Which Is Better?

June 25th, 2019


Indulging in tea is a tradition people all around the world have in common. While there are many different types of teas differentiating between flavors, uses and originating plants, two teas, green and black, are two of the most common teas with a very long history of being enjoyed by many.


In this article, we will cover the similarities and differences between both teas and help you decide which is the better tea for you.



Did you know that both black and green and black tea are actually made from the same leaves?

Both green and black tea come from the leaves of the Camellia sinensis plant. The main difference is that black tea is fermented and green tea is not.

Fermentation is the process where the tea leaves are rolled up and exposed to the air. This process darkens the tea leaves and causes the flavors to intensify.


In this article, we will talk about the similarities between the two teas and then share the differences between both green and black tea. We will then help you decide which tea may be more beneficial to you, based on your health needs.



  • Both teas are full of antioxidants which helps to lower inflammation, decrease the risk of cancer and heart disease and overall improves brain function. Green tea does contain more antioxidants than black tea. We will discuss this further below.

  • Both teas contain Fluoride which is known to strengthen bones and teeth.

  • Both teas contain caffeine and L-theanine which has a calming but alert effect. Green tea has more L-theanine while black tea has more caffeine. Green tea has about ¼ the caffeine as your cup of coffee and black tea has about ⅓ the caffeine.

  • Both teas help reduce “bad” LDL cholesterol and triglycerides as well as blood pressure.

  • One animal study found that both green and black tea were equally effective in preventing blood vessel plaque formation by 26% with minimal consumption and 68% with the highest consumption.



Black Tea (listen benefits below are a result of drinking at least 3 cups daily.)

  • Hydrates the body and strengthens the immune system with bacteria-fighting antioxidants.

  • Promotes blood flow to the brain which improves focus and concentration. This has given black tea the name “eye-opener”.

  • Rich source of theaflavins. This helps reduce liver enzymes and increases liver function as well as helps to decrease the amount of plaque in the heart and in blood vessels.

  • Antibacterial agent- damaging the bad bacteria from your body.

  • Significantly reduces cholesterol and blood sugar levels.

  • Known to promote fat breakdown, thus helping with obesity and weight loss.


Green Tea (listen benefits below are a result of drinking at least 3 cups daily.)


Very rich in EGCG (epigallactocatechin gallate)  due to no fermentation

ECGC has the following effects:

  • Inhibit the multiplication of cancer cells

  • reduce the harmful effects of amyloid plaques that build up in Alzheimer’s patients

  • Anti-fatigue.

  • Decreased levels of fatty liver

  • Antimicrobial properties→ damage to bacteria cell walls and can reduce transmission of some viruses

  • Calming effect on mind and body

  • Since oxidation is arrested, it is believed that more polyphenols are preserved. This supports weight loss programs that include diet and exercise

  • Less acidic, therefore washing off acidic waste

  • Detoxifying effects → glowing skin, boosted metabolism and stronger immunity


Which one should you drink?


When looking at the overall breakdown of both teas, green and black tea are very similar in terms of their properties and benefits. While green tea is EGCG rich and black tea is theaflavin rich, both teas are a great source of antioxidants and help you lower your blood pressure and weight, and can boost positive heart health.

If you are struggling with fatigue and mental fogginess, black tea may be better for you. With more caffeine than green tea, black tea is known to be a good pick-me-up and can help you feel more alert and focused. Black tea may also be best if you are someone who is trying to lower your blood pressure and sugar levels.

While both teas have some differences, they are overall very similar in terms of shared health benefits, especially for your heart, brain and metabolic system.  However, it is important to remember that to retrieve the health benefits of these teas, they should be consumed at least 3 times a day, and can be consumed with or without food.
