Benefits of Green Tea Extract

green tea extract

Green Tea is the most popular tea consumed all around the world. Even if you’re not a typical tea drinker, chances are you’ve had green tea at some point in time. It’s known for being an excellent source of antioxidants that are credited for offering a wide range of health benefits from improving skin health to reducing cancer risks. Green tea extract is the concentrated form of green tea, and just one capsule of the extract offers the same active ingredients as the average cup of green tea. Green tea extract is being researched extensively for its potential ability to aid with weight loss, and it is included in a number of weight loss products as a primary ingredient.

Our fat burner, Cinerate, includes green tea extract as one of its powerful ingredients to help explode the excess fat off your body. It helps decrease your appetite, increase energy, and enables extreme mental focus.

Let’s take a look at the variety of benefits people experience when using green tea extract:

Green Tea Extract is High in Antioxidants

Antioxidants are known for fighting the effects of cell damage caused by free radicals in the body. Free radicals are those little evil wrong-doers in the body that contribute to the process of aging and diseases. So, antioxidants are the good guys that fight against the bad guys, the free radicals. Got it?

Green tea extract offers many health benefits as a result of being loaded with antioxidants, polyphenol antioxidants called “catechins”, to be exact [1].  Studies show considerable increases in the blood antioxidant capacity when people take green tea extract. In a study involving 35 obese individuals given 870 mg of green tea extract for eight weeks, the antioxidant capacity of the blood increased from 1.2 to 2.5 umol/L on average. With greater antioxidant capacity in the blood the body can better protect itself against oxidative stress.

Any Green Tea Extract Side Effects to Worry About?

As with any supplement you should take note of any potential side effects that you may experience when taking green tea extract. Everyone responds differently to green tea extract, much like everyone experiences coffee in different ways. Some people get hyper, others feel more focused and energized, and some get jittery. The side effects of drinking coffee are similar to the side effects associated with green tea extract [2]. Some people report heart palpitations, anxiety, and feeling somewhat “weird” afterward. If you try it and don’t like the way it feels, try taking it with food and water. If you still have negative side effects, it may not be a good supplement for you.

Catechins and Caffeine in Green Tea Extract Assist with Weight Loss

The combination of catechins and caffeine, both contained in green tree extract, is responsible for giving green tea its weight loss properties. They play a role in regulating hormones in the body that improve thermogenesis [3]. Thermogenesis is the process your body goes through when burning calories in order to digest food and create heat. When you consume green tea, thermogenesis is enhanced and the result is a body that is more effective in burning calories.

To examine the effect on calorie burning, studies of green tea extract have been conducted. In one study, 14 people were given a supplement which contained EGCG from green tea and guarana extract and caffeine before each meal. It was found that the participants burned an average of 179 more calories in the following 24 hours than people who did not take the supplement.  A similar study with 10 healthy men participants found that they burned 4% more calories in the 24 hours after taking the green tea extract supplement with 50 mg of caffeine and 90 mg of EGCG.

When it came to weight loss, another study lasting 12 weeks with 115 overweight women resulted in a 2.4lb weight loss among participants taking 856 mg of green tea extract per day.

Protect Your Brain

Antioxidants like EGCG, found in green tea extract, are known to protect brain cells from oxidative stress. Why wouldn’t you want to keep your noggin sharp?! Protecting brain cells may reduce your risks of mental decline and diseases like Alzheimer’s, Parkinson’s, and dementia. Studies have also shown green tea extract to help strengthen memory since it improves the connection between the various parts of the brain [4].

In a study involving 12 people drinking 27.5 grams of green tea extract or a placebo, the group worked on memory tests. Researchers captured images of their brain to assess the brain functioning. The group consuming green tea extract showed improved task performance and braining functioning when compared to the group drinking a placebo.

Boost Your Heart Health

healthy heartYour heart is the engine from which everything else in your body gets its power.  Keeping your blood pressure and blood fat levels within normal ranges will reduce your risk factors for heart diseases and boost your overall heart health. Over time, oxidative stress will increase the buildup of fat within the blood and cause inflamed arteries and high blood pressure. You can use green tea extract to decrease the inflammation and reduce blood pressure.

In a study of 56 obese individuals with above normal blood pressure, it was found that taking 379 mg of green tea extract each day over a period of three months would decrease their blood pressure significantly compared to individuals who were not taking GTE. In addition to lowering blood pressure, the extra promoted reductions in the amount of fat in their blood, lower triglycerides and LDL cholesterol.

Minimize Your Risks of Cancer

When the normal life cycle of your cells is disrupted, cancer may occur. Healthy cells will die off and regrow, with healthier cells replacing those that die. It’s a process your body performs over and over from the day you are born. But if the balance is thrown off, you could produce extra cells and the old cells may fail to die off the way they should. This leads to cancer. When you consume green tea extract with EGCG, your cell health is improved and cell production is balanced, which may minimize your risks of cancer. A study of postmenopausal women who were at high risk for breast cancer consumed 1315 mg of green tea extract daily for 12 months and experienced a decrease in the biomarkers of breast cancer. More research is needed, but there is a potential for GTE to help prevent some types of cancer, along with all of its other health benefits [5].

Improve the Functioning of Your Liver

There have been a variety of studies that also show green tea extract to benefit liver function, however, it is important to note that exceeding the recommended dosage for green tea extract has the opposite affect and can harm the liver. This is a clear example of  the possibility of “too much of a good thing”!

The catechins can help reduce liver disease-caused inflammation, like non-alcoholic fatty liver disease [6]. A study of 17 patients with non-alcoholic fatty liver disease (NAFLD) took 700 ml of green tea that contained a minimum of 1 gram of catechins every day for 12 weeks.  They were tested and showed decreases in inflammation, oxidative stress, and liver fat content.

Another study indicated improved liver health in the form of reduction in liver enzyme levels.

Make Your Skin Healthier (And Look Better)

Our skin is subjected to everything in the environment, from harsh chemicals to air pollution, to the not-so-healthy things we consume at times. As a result, it may display a variety of problems from warts to dermatitis to rosacea, acne, or general skin rashes.  Green tea extract can improve the health of your skin, and therefore give it a better appearance [7]. For example, when applied directly to the skin, green tea extract can treat warts, dermatitis, rosacea and acne. It can give skin a more youthful appearance. In a study of individuals consuming 1500 mg of green tea extra per day for four weeks, there was a significant reduction in red skin bumps from acne.

Using green tea extract directly on the skin or as a supplement can prevent loss of skin elasticity, premature aging, cancer from exposure to UV rays, and inflammation symptoms.

Some cosmetic products also contain green tea extract as a moisturizer.

Keep Blood Sugar Under Control

Green tea extract can offer a variety of blood sugar benefits such as improved insulin sensitivity and lower blood sugar levels [8]. A common struggle of obese individuals is elevated blood sugar levels, so if you can manage appropriate blood sugar levels you may avoid or reduce problems associated with being overweight.  High blood sugar levels are also commonly associated with diabetes, which in turn increases your risks for heart disease, regardless of your age, and particularly for women. If you can help keep it under control with something as simple as green tea extract… you should, right?

Green Tea Extract is Good for Just About Everything!

The high antioxidant content of green tea extract improves your health and body composition. From helping you lose weight to regulating blood sugar to preventing disease, promoting strong brain functioning to a healthy liver and improving your skin condition – it’s like the full body supplement you never knew you needed.

Green tea extract is available in capsules, liquids, and powder form. It’s often included as an ingredient in other performance or health enhancing supplements – including our fat burner, Cinerate. It’s an easy way to add antioxidants into your diet and take advantage of the wide variety of health benefits they provide.

green tea extract health supplementsIf taking the liquid form of green tea extract, you can dilute it in water. Powder can be mixed into your smoothies or meal replacement shakes.  The recommended daily dosage of green tea extract is between 250 and 500 mg. While you can get the equivalent from drinking three to five cups of green tea, not everyone is up for the challenge of drinking that many cups of tea every day! Remember not to exceed the recommended daily dosage, as studies have shown too much of green tea extract can result in liver damage.
