EGCG Powder

What is EGCG?

Green tea extract EGCG Powder is the most effective active ingredient in tea polyphenols and belongs to catechins. EGCG has antibacterial, antiviral, antioxidant, antiarteriosclerosis, antithrombosis, antivascular proliferation, and anti-inflammatory effects. There is EGCG in green tea, but not in black tea. Because the EGCG in black tea is converted into thearubigin. EGCG powder has the functions of preventing and treating various diseases and enhancing immunity in medicine and health care; it can be used as antioxidant, antibacterial, fresh-keeping, and deodorant in the food industry; it can be used as a preservative and skin care agent with special functions in daily chemical products. 

Epigallocatechin gallate is the most effective active ingredient in catechins, accounting for approximately 8% to 13% of the gross weight of green tea, and is also the component with the highest content of catechins. (-)-Epigallocatechin gallate is an ester formed by α-phenol benzopyran and gallic acid. It has phenolic antioxidant properties and has 6 ortho-positioned phenolic hydroxyl groups in its molecular structure. , so it has many properties superior to other catechins.

What are the benefits?

It has been shown to protect against:

Acts as an antioxidant and free radical scavenger

Fight inflammation/inflammatory diseases by inhibiting the activity of pro-inflammatory chemicals

block neurodegeneration

Has metal chelating ability

Supports metabolic activity that may prevent weight gain and metabolic syndrome

May help reduce the development of diabetes, heart disease, and neurodegenerative diseases

Here's more information about some of the most well-known ECGC benefits:

1. Fight oxidative stress/inflammation

Studies investigating EGCG have found that it inhibits the accumulation of reactive oxygen species, alters signaling pathways in a way that prevents excessive inflammatory responses, lowers nitric oxide levels, and reduces oxidative stress.

There is also evidence that this polyphenol interacts directly with proteins and phospholipids and regulates signal transduction pathways, transcription factors, DNA methylation, mitochondrial function, and autophagy (how the body clears damaged/dead cells).

All of this translates into enhanced protection against a variety of health issues, especially those related to inflammation and aging.

2. Support heart health

The catechins in tea are thought to be responsible for many beneficial health effects related to the heart and blood vessels.

According to Harvard Health Publishing, flavonoids help suppress inflammation, which in turn can reduce plaque buildup in arteries, improve blood vessel reactivity, improve blood pressure and help lower LDL cholesterol levels.

There is also evidence that people who drink tea regularly may have a reduced risk of heart disease or stroke.

3. Help protect the brain

Researchers believe that EGCG is neuroprotective due to its antioxidant effects and ability to invoke a range of cellular mechanisms in the brain. Consumption has been linked to increased protection against neurodegenerative diseases such as Alzheimer's, dementia and Parkinson's disease.

Some studies have found that catechins can help reverse nerve damage and prevent further nerve death, thereby reducing the decline in cognitive function that occurs with age.

A number of large studies have found that adults who drank two to three cups of green tea per day for at least several years had a reduced prevalence of cognitive impairment, resulting in a 30 to 40 percent lower risk of developing Parkinson's disease.

In addition to suppressing cognitive dysfunction, EGCG may also help improve learning by reducing oxidative damage in the brain.

4. Supports healthy metabolism/weight loss

While not a quick fix for weight loss, there is some evidence that this compound may prevent metabolic syndrome and promote fat loss in several ways—such as reducing inflammation, suppressing appetite, and increasing energy expenditure. EGCG may also work in part by promoting thermogenesis (the body's use of energy to produce heat), although not every study finds evidence that these effects are significant.

In some studies, drinking two or more cups a day is associated with healthier body composition.

For stronger effects, EGCG and caffeine can be consumed together (such as from tea or some extracts and supplements). One study found that taking an EGCG supplement along with caffeine for several months helped help overweight adults lose fat.

Epigallocatechin gallate (EGCG) is an ingredient extracted from Chinese green tea. It is the main active and water-soluble component of green tea. It is the component with the highest content of catechins, accounting for 9% of the gross weight of green tea. -13%. Because of its special stereochemical structure, EGCG has very strong antioxidant activity. The antioxidant activity is at least 100 times that of vitamin C and 25 times that of vitamin E. It can protect cells and DNA from damage. Damage believed to be associated with heart disease and other critical illnesses is attributed to EGCG's ability to scavenge oxygen free radicals (antioxidants).

EGCG Powder is the main component of green tea polyphenols and the main component of green tea catechins. The catechins include EGCG, EGC, ECG, EC, GCG, etc., among which the antioxidant activity is in order of EC. Many studies have shown that EGCG has antioxidant properties. Free radical DNA damage, resistance to radiation and ultraviolet rays, preventing lipid peroxidation, reducing the levels of low-density cholesterol, ultra-low-density cholesterol and triglycerides in serum, inhibiting carcinogens in the diet, and interacting with other substances in the intestines, liver, and lungs Enzymes and antioxidants scavenge free radicals, resist the effects of pollution, sun exposure and smoking, and prevent skin aging and wrinkles.

Application direction

1. Medicine and health care

EGCG Powder has significant antioxidant, free radical scavenging and anti-mutagenic effects, can enhance immune system function, inhibit the growth of liver fat and cholesterol, and also has a strong inhibitory effect on dysentery, typhoid, Staphylococcus aureus and other bacteria.

EGCG also has functions such as anti-aging, lowering blood lipids, improving low-density lipoprotein, preventing atherosclerosis, and enhancing immunity; it can inhibit the proliferation of glomerular cell membranes and improve kidney function; it can effectively inhibit hyaluronidase, reduce inflammation and allergy.

2. It can be used as antioxidant, antibacterial, fresh-keeping and deodorant in the food industry.

3. Preservatives and skin care agents with special functions in daily chemical products

At normal temperature, low-concentration EGCG has strong antioxidant, free radical elimination, sterilization and odor removal functions. Therefore, adding a small amount of EGCG can prevent cosmetics from deteriorating. As a natural biochemical raw material for cosmetics, EGCG has the following characteristics compared with other biochemical raw materials: it has a small molecular weight, is easily absorbed by human skin, and has good transdermal absorption performance; its activity is extremely stable, and temperature has minimal effect on changes in its activity. Under acidic and light-enclosed conditions, the activity remains unchanged for a long time; it is safe and reliable. After inspection by relevant professional institutions, its toxicological testing and micronucleus test show that it is a non-toxic and non-irritating substance, which meets the quality standards of daily chemical products; the dosage is small, Strong effect; has strong antioxidant activity, its antioxidant capacity is 2-4 times that of DHA and BHT, and is effective at low concentrations.

The role of EGCG in cosmetics is summarized as follows:

⑴ Anti-wrinkle and beauty effect;

⑵ Sun protection and anti-spot effect;

⑶Relieve the toxic effects of heavy metals;

⑷ Antibacterial and anti-inflammatory effects;

⑸ Promote skin microcirculation, etc.;

(6) It can eliminate skin freckles and yellow spots and make the skin smooth.
