Here's what you need to know about green tea extract and its promising health effects. 

Green Tea Extract 

So, what exactly is green tea extract?

Green tea extract is the concentrated form of essence extracted from the dried leaves of Camellia sinensis. Black, green, and oolong tea are the other tea extracts from the same plant.

Epigallocatechin gallate has active energy-boosting potentials,  making it an active energy drink ingredient. 

Other active compounds present in green tea extracts include: 

  • Theobromine 
  • Theophylline 
  • Caffeine

Polyphenol antioxidant, Epigallocatechin gallate is the potent component behind the energy-boosting capability of green tea extract. 

In addition, caffeine in green tea also adds a punch to the overall energizing effect. The presence of amino acid (L-theanine) works synergistically with caffeine, thus enhancing the overall working capacity. Various researchers have concluded that green tea extracts improve athletic performance and endurance. 

Green Tea Cancer Preventing Potential

Cancer is one of the most prevalent diseases. The cancer formation is primarily due to the oxidative damage caused by the free radicals within the blood. The increased oxidative stress causes cancer and impairs the immune system. 

In research, groups that are active consumers of green tea extract or other forms of green tea show less cancer incidence than others who don't. 

The polyphenols present in green tea extract render both anti-oxidant and anti-cancer capabilities. The catechins are active in controlling progressive cancer cell growth and preventing tumor cells from replicating.   

In addition, catechins also relieve muscle fatigue, thus rendering an overall relieving effect. 

Green tea extract has been able to treat the most prevalent cancers, including breast, colorectal, and prostate cancer.

Green Tea Improves Brain Functioning 

If you are having a busy day or are thoroughly exhausted, green tea will be a miracle to boost your overall performance. 

Catechin present in green tea works as a stimulant. It does so by preventing the release of adenosine, which works as a neurotransmitter inhibitor. By doing so, green tea extract boosts the release of norepinephrine and dopamine, thus improving brain function. 

In addition to this, green tea also regulates mood and memory. L-theanine in green tea renders anti-anxiety effects by stimulating the release of GABA.

If you ask Google for something that would help you eliminate all the deposited fat, google will add “green tea good for fat consumption” to the top of the list. 

The catechins can potentially accelerate the metabolic pathway of fat breakdown. In addition, it also boosts the release of catecholamines which are responsible for the release of fat in the blood. They also prevent the release of any inhibitor for catecholamines release. 

In short, the intake of green tea extract in the form of tea or capsules prevents the release of LDL and increases the HDL level of blood, thus improving overall health.

But it is best to take things in moderation as excessive consumption of everything will eventually lead to alarming consequences.

In addition, green tea is also promising in delaying skin aging and increasing skin elasticity.

Thus, the intake of green tea protects the liver from inflammation and other oxidative damage.
