Green Tea Catechins Dosage & Review

Green Tea Catechins Review Green Tea Catechins are the major polyphenolic compounds in green tea extracts that have various physiological effects that greatly benefit human health. They are known to be effective antioxidant agents by scavenging free radicals , chelating redox active transition-metal ions, inhibiting redox active transcription factors, inhibiting pro-oxidant enzymes and inducing antioxidant enzymes. Green Tea Catechins also improve blood lipid profile by inhibitng the key enzymes involved in the biosynthesis of lipids and serves to reduce intestinal lipid absorption. Moreover, catechins have been wshown to inhibit proliferation of vascular smooth muscle cells by interfering with vascular cell growth factors involved in arthrogenesis. They also suppress platelet adhesion thus, inhibiting thrombogenesis. In addition to thaat, Green Tea Catechins also regulate vascular tone by inhibiting endothelial nitric oxide as well as preventing vascular inflammation that plays a critical role in the progression of atheroscleoritc lesions. It is also known as Camellia sinensis, Green Tea Extract, GTE.

Green Tea Catechins Review: What is Green Tea Catechins?

Green Tea Catechins

Overview and Information

Green tea is the type of beverage that is very popular in the Western part of the world. This was once a favorite of the Asian people, and has captivated the Western people as well. Green Tea Catechins contains a lot of health benefits including boosting the function of the immune system, preventing the development of many types of cancer, decreasing the levels of low-density lipid (LDL) cholesterol, delaying the onset of age-related cancers, relieving pain, reducing blood sugar levels, fighting against tooth decay, and reducing the risk of cardiovascular disease (stroke).

Green tea contains high amounts of catechins, which are known as a specialized group of polyphenols. Catechins are the ones that give green tea its astringent flavor and is the primary reason for most of its health benefits by acting as detoxifiers, antioxidants, and antiseptics. Green tea is known to be the best dietary source of catechins and contains about 8 types of it, the major ones being epigallocatechin and epigallocatechin gallate. Unlike other teas, such as black tea and oolong, green tea has the ability to retain more catechins – as much as 30 to 42 percent of dried leaf weight compared to the black tea which is only about 9 percent.

What are the benefits of Green Tea Catechins?

Fight against Cancer

Many population-based studies show that both green tea and black can fight against cancer. One example that can prove this claim is cancer rates tend to be lower in countries where people drink green tea in a regular basis such as Japan. On the other hand, it not possible to know from these research studies if green tea could actually prevent cancer in people. Recent clinical studies show that the polyphenols found in tea, especially green tea, plays an important role in preventing the development of different types of cancer. Many experts believe that polyphenols can kill malignant cells and prevent them from growing.

Lowers cholesterol levels

Research studies conducted on both humans and animals reveal that green tea has the ability to increase the levels of high-density lipid (good) cholesterol and decrease the levels of total cholesterol. A population-based study shows that individuals who are consuming green tea regularly tend to have lower cholesterol levels than those who do not. One animal study shows that polyphenols in green tea could block cholesterol from being absorbed the small intestine and helps the body get rid of low-density lipid (bad) cholesterol. In another study conducted on men who smoke, researchers discovered that green tea could dramatically decrease the levels of low-density lipid (bad) cholesterol.

Prevents the development of Atherosclerosis

Atherosclerosis a disease of the arteries characterized by the deposition of plaques of fatty material on their inner walls. This is one of the leading cause of death in the United States. Population-based studies are studies that compare groups of people who have different diets and different cultures or observing large groups of individuals over a long period of time. According to these studies, the antioxidant properties of green tea could help prevent the development of atherosclerosis, especially coronary artery disease. Experts believe that green tea decreases the risk of heart disease by reducing the levels of triglyceride and total cholesterol. Some studies show that black tea also contains similar effects. As a matter of fact, experts estimated that consumption of 3 cups per day could decrease the rate of heart attack by 11 percent.

Enhances brain function and make you smarter

Aside from keeping you awake green tea also has the ability to make you smarter. The key ingredient is caffeine, which is known as a stimulant. Green tea does not contain too much caffeine, but it has enough to promote a response without causing the “jittery” effects following the consumption of high amounts of coffee. Adenosine is an inhibitory neurotransmitter of the brain. What caffeine does is block the Adenosine, thus resulting to increase in concentration of certain neurotransmitter like norepinephrine and dopamine as well as the firing of neurons.

Caffeine has been thoroughly studied by some experts and was found to be effective in improving various aspects of brain function including enhancement of memory, improving mood, reaction time, and vigilance. However, green tea contains more than just caffeine, it contains L-theanine, which is a compound that can cross the blood-brain barrier. L-theanine enhances the activity of an inhibitory neurotransmitter known as gamma-Aminobutyric acid (GABA). GABA has the ability to increase the production of alpha waves and levels of dopamine inside the brain and has anti-anxiety effects.

Researchers discovered that L-theanine and caffeine have synergistic effects. If these two are combined, it could have strong effects on brain function. Because of the combination of L-theanine and small amount of caffeine, green tea can produce much milder effects and different kind of alertness as compared to coffee. According to many user reviews, drinking green tea could promote a more stable energy and helps a person to be much more productive than drinking coffee.

How much should you need to take?

ADULTS

Depending on the brand, the recommended amounts of standardized green tea extract are about 100 to 750 mg a day or 2 to 3 cups a day (for a total of 240 to 320 mg of polyphenols).

PEDIATRIC

There are no studies or evidence available to determine if green tea is safe for pediatric use, therefore it is much better stay on the safe side and avoid giving it to children.

What precautions should you need to take?

Herbs are widely used by most people in the world to treat various types of diseases and promote enhanced body strength. However, herbs contain active substances that could cause side effects and react unfavorably when used in combination with other herbs, medications, or supplements. Therefore, it is important that you take herbs with care and talk to your physician of any qualified medical professional before deciding to use any of it.

Individuals who have glaucoma, anemia, osteoporosis, and diabetes are advised to talk to their physician before drinking green tea or taking an extract. Individuals who are suffering from kidney problems, high blood pressure, heart problems, psychological disorders (particularly anxiety), liver problems, and stomach ulcers are advised to avoid taking green tea or an extract. Women who are pregnant and lactating should also avoid taking it.

Individuals who drink large amounts of caffeine for long periods of time reportedly experience insomnia, irritability, dizziness, and heart palpitations. Caffeine overdose can lead to vomiting, nausea, headaches, diarrhea, and decreased appetite. On the off chance that you consumed a lot of green tea and begin to vomit or have abdominal spasms, you may have caffeine poisoning and should consult your physician as soon as possible.
