Green Tea Extract – Health Encyclopedia

As the world is steering keenly toward healthier options, many normal masala teacups are being replaced with hot and delicious green tea. This herbal drink is known for its ability to digest food organically. Along with all other benefits it contributes to the human body, green tea has become one of the most consumed beverages in the world. 

Since its discovery in China thousands of years ago, green tea has been used for its medicinal properties. It has been used as a staple herb in traditional medicines. Many scientists believe that green tea possesses tremendous potential for aiding many diseases and they have been spending years analyzing the potential health benefits and drawbacks of this precious herb.

What is Green Tea?

Green tea is made from a tea plant called Camellia sinesis. The leaves and buds of this plant are hand-picked for making green tea and several other teas such as black and oolong tea. Green tea is made by drying the leaves through pan-frying to prevent oxidation. This helps to keep the colour of the leaves intact. Also, since green tea is not fermented, it is able to keep in an important molecule called polyphenols which preserves the healthy nutrients and antioxidants in the leaves. Green Tea also contains a small amount of caffeine. 

What is Green Tea Extract?

Green tea extract is a concentrated form of green tea leaves and is made from the crushed ground powder of the leaves. According to studies, one capsule of green tea extract contains the same amount of active ingredients as in an average cup of green tea. 

Like green tea, green tea extracts are also an amazing source of antioxidants. Green tea extract is known for its wide range of health benefits and also for its strong defense against several health ailments. Some of the health benefits of green tea extract include:

  • High in antioxidants

Antioxidants can allow your body to fight oxidative stress by preventing cell damage produced by chemicals known as free radicals. Free radicals can cause health problems when they interact with damaged or degraded cells. Free radicals are responsible for oxidative stress, which has been related to cancer, liver damage, premature ageing, and heart disease. Catechins, a type of polyphenol antioxidant, make up the majority of the antioxidant content in green tea extract. Epigallocatechin gallate (EGCG) is the most investigated catechin in green tea and is regarded to have the most health benefits. EGCG helps to fight free radicals. According to research publishes in the European Journal of Nutrition, after rigorous exercise, athletes who consumed green tea extract had considerably reduced levels of oxidative stress.

  • Promotes Heart Health

Oxidative stress causes fat deposition in the bloodstream, which causes artery inflammation and high blood pressure. Green tea extract contains antioxidants that can help lower inflammation and blood pressure. They can also help reduce blood fat levels by inhibiting fat absorption in cells. Since green tea catechins may help lower blood pressure and enhance blood fat levels, all of which are beneficial to heart health.

  • Good for brain functioning

Green tea extract antioxidants, particularly EGCG, have been demonstrated to protect brain cells from oxidative stress. This shield can help protect the brain against damage that can lead to mental decline and disorders like Parkinson’s, Alzheimer’s, and dementia. Heavy metals like iron and copper, both of which can harm brain cells, can be reduced by green tea extract. It has also been found to improve memory by strengthening the connections between different sections of the brain.

  • Aids in weight management

Green tea extract is high in catechins and has moderate caffeine content. Green tea extract’s mild weight loss benefits appear to be due to this combination of components, which is interesting. Caffeine and catechins have both been demonstrated to aid weight loss by modulating hormones that promote thermogenesis. The process by which your body uses calories to digest food and produce heat is known as thermogenesis. Green tea has been demonstrated to aid this process by increasing the efficiency with which your body burns calories, resulting in weight loss.

Those who are caffeine sensitive or have cardiovascular problems should think about this before taking green tea extract for weight loss. It’s always a good idea to see a healthcare professional before deciding whether or not green tea extract is suited for you. You can get in touch with us at to consult our healthcare professionals.

  • Helps in Liver Functioning

Green tea extract’s catechins may also assist to lessen inflammation caused by liver illnesses including nonalcoholic fatty liver disease. It also lowers the level of oxidative stress.

  • Reduces the risk of cancer

Cell death and regrowth characterise the upkeep of your body’s tissues and organs. Stem cells are specialised cells that make new cells to replace those that perish. This procedure keeps cells healthy and active. Cancer can develop if this balance is interrupted. This is when your body begins to produce abnormal cells that do not die when they should. According to studies, green tea extract antioxidants, particularly EGCG, appear to have beneficial effects on the balance between cell creation and death. Since this extract has been shown to maintain cell health, it might help in the prevention of cancer. More studies are required to understand this in detail.

  • Good for healthy skin

Green tea extract has been demonstrated to promote skin health when taken as a supplement or applied to the skin. Green tea extract, when applied to the skin, can help treat a range of skin issues, including dermatitis, rosacea, and warts, according to a major review. It has been demonstrated to aid with skin ageing and acne when taken as a supplement.

  • Helps to lower blood pressure

Green tea catechins, particularly EGCG, have been proven to improve insulin sensitivity and regulate blood sugar synthesis, both of which can help to lower blood sugar levels. Green tea extract has been demonstrated to improve insulin sensitivity and tolerance while also lowering haemoglobin A1C and blood sugar levels.

  • Benefits of exercise and recovery

Green tea extract appears to benefit from exercise, whether it’s via enhancing recovery or improving performance. While exercise has numerous health benefits, it is also known to cause oxidative stress and cell damage. Green tea catechins, for example, can prevent cellular damage and delay muscular weariness.

Side effects of Green Tea Extract

Caffeine in green tea might create adverse effects. Anxiety, tremors, impatience, and sleeping issues are examples of these symptoms. If you’re sensitive to caffeine or take excessive dosages, this is more likely. Green tea has fewer side effects than other caffeine-containing beverages. This is due to the leaves steeping for a shorter period of time.

Green tea’s fluoride concentration may help prevent tooth decay. Tannic acid is also present in the tea. This might discolour your teeth.

Green tea extracts may irritate the liver. Yellowing of the skin or the whites of your eyes, nausea, and stomach pain are all possible symptoms. Stop drinking green tea and visit your doctor immediately away if you’re experiencing these symptoms. Green tea extract’s harmful effects on the liver may vary depending on how much you consume each day.
