Green Tea Prevents Skin Cancer By Enhancing DNA Repair


What is green tea extract?

Odds are you’re familiar with green tea, one of the most consumed drinks in the world. Well, green tea extract is basically a concentrated form of the popular tea that’s made from dried green tea leaves.

Green tea is full of antioxidants and plant compounds called catechins that provide the foundation for many boost-your-health claims.

In fact, a catechin named epigallocatechin gallate or EGCG, gets most of the marketing attention. You’ve probably seen its presence hyped on energy drinks and supplements.

Health Benefits of Green Tea Extract

1. Support Weight Loss

The most widely known health benefit of green tea extract is its ability to speed up weight loss. Green tea pills contain high concentrations of tea catechins, flavonoids, and green tea polyphenols, which are antioxidants.

Catechins speed up metabolic rate. This helps trigger the release of fatty acids, which the body breaks down into energy. These compounds essentially encourage the body to burn existing fat stores to produce energy. Catechins may help to control body weight – especially when in high concentrations such as green tea pills or matcha green tea from Japan.

2. Detoxify the Body

Green tea extract supplements contain antioxidant properties that help to cleanse the body of free radicals. Uncharged cells or free radicals are highly reactive in the human body.

3. Green tea prevents non-melanoma skin cancer

UV-induced DNA damage, particularly the formation of cyclobutane pyrimidine dimers, has been implicated in immunosuppression and initiation of skin cancer. Topical application or oral administration of green tea through drinking water of mice prevents UVB-induced skin tumor development, and this prevention is mediated, at least in part, through rapid repair of DNA. The DNA repair by GTPs is mediated through the induction of interleukin (IL)-12 which has been shown to have DNA repair ability. The new mechanistic investigations support and explain the anti-photocarcinogenic activity, in particular anti-non-melanoma skin cancer of green tea and explain the benefits of green tea for human health.

Green tea pills may help lower your risk of cancer thanks to its free-radical fighting properties. Most research has been in the lab or on animals, although there are a few human clinical trials. Green tea extract also works most effectively on certain types of cancer including breast cancer, prostate cancer, and liver cancer.

The findings of another large study were in the American Journal of Clinical Nutrition in 2009. Dr. Yang and his team of scientists researched 3,234 incidences of cancer among 38,408 women over a period of 11 years. During the course of this study, researchers found that tea catechins correlate with lower risk of cancer.

4. May Support Heart Health

Taking green tea extract may protect against heart disease thanks to its anti-inflammatory properties. Green tea contains active ingredients such as antioxidants that help to reduce inflammation that can lead to high blood pressure and clogged arteries – risk factors of cardiovascular disease.

5. Supports Brain Health

Green tea may also help to enhance memory recall. A study published in Psychopharmacology examined the effects of green tea on memory processing. Participants who consumed green tea had improved task performance and memory recall than those that received a placebo. These results may be particularly useful for patients who suffer from dementia.

6. May Lower Blood Sugar

One of the leading causes of death in the United States and Canada is Type 2 Diabetes. This disease results in serious complications including death due to the body’s inability to process insulin properly. Green tea pills may help regulate blood sugar and decrease insulin resistance.

A study published in the Journal of Biological Chemistry found that green tea catechins—EGCG specifically—enhance insulin sensitivity and regulate the release of blood sugar. By lowering blood sugar levels, green tea pills help prevent symptoms of diabetes including dizziness.

7. May Boost Liver Function

The detoxifying powers of green tea pills may help to promote healthy and improved liver function. Green tea has been particularly useful in treating liver injury and liver disease caused by nonalcoholic fatty liver disease, also known as NAFLD.

Suggested dosage

Green tea extract comes in oral capsules. It’s available in different strengths. You can buy medizen-green-tea-extract and take 1 tablet each day. Though we recommend you to connect with an expert at to know the best dosage plan for you. 

Green tea as loose, dried leaves or in tea bags should be steeped in hot water for a short time. Make sure the water isn’t scalding. experts do this to preserve important chemicals in the leaf.

Side effects

Green tea can cause side effects due to caffeine, if taken in overdose. These can include anxiety, tremors, irritability, and sleeping problems. This is more likely if you’re sensitive to caffeine or take large doses. 

Side effects are less common with green tea than with other drinks that have caffeine. This is because experts steep the leaves for a shorter time.
