A sip of green tea is full of antioxidants, which not only invigorate the senses, but also hold the key to a fountain of youth. We're talking about epigallocatechin gallate (EGCG), the superhero among the antioxidants in green tea. In addition to its enchanting aroma and fine taste, EGCG has an excellent reputation for its diverse health and anti-aging effects.

What is EGCG?

EGCG, or epigallocatechin gallate, is a type of catechin — a compound from plants known for its antioxidant properties. Among catechins, EGCG stands out for its high antioxidant activity, which can help combat the effects of free radicals and slow down cell aging.

Where can you find it?

The richest source of EGCG is green tea, particularly varieties such as matcha, which contain a concentrated dose of this compound. Although other types of tea, such as white tea and oolong tea, contain lower amounts, green tea is considered the best source. There are also dietary supplements with green tea extract, but they should only be taken under expert guidance.

EGCG and Longevity

Research suggests that EGCG may play a role in promoting longevity through various mechanisms:

‍

1. Combating oxidative stress

Oxidative stress is one of the main factors for cell aging and chronic diseases. The powerful antioxidant properties of EGCG help neutralize free radicals, reduce cell damage and potentially slow down the aging process. This can reduce the risk of age-related diseases.

‍

2. Heart health support

Cardiovascular diseases are one of the most common causes of death worldwide. EGCG has been shown to support heart health by reducing cholesterol and blood pressure and improving blood vessel function. These benefits are another reason why EGCG can contribute to a longer life expectancy.

‍

3. Supports a healthy weight

Maintaining a healthy body weight is crucial for a long life. EGCG has been shown to stimulate metabolism, improve fat oxidation, and may help with weight loss. By supporting healthy weight management, EGCG could help prevent a wide range of obesity-related health problems and shorten life expectancy.

4. Protecting brain function

Neurodegenerative diseases such as Alzheimer's and Parkinson's are linked to aging. EGCG's ability to cross the blood-brain barrier makes it possible to protect brain cells from oxidative stress and inflammation, potentially reducing the risk of cognitive decline.

‍

5. Anti-cancer properties

Cancer affects almost everyone who wants to live a long and healthy life. EGCG can inhibit the growth of cancer cells, induce apoptosis (programmed cell death), and prevent cancer cells from spreading. These properties are promising for a long life, although further research is needed.

6. Reduce inflammation

Chronic inflammation is associated with various age-related diseases and aging itself (so-called “inflammaging”). The anti-inflammatory effects of EGCG can help reduce the effects of inflammatory diseases, leading to healthier aging and improved quality of life.

7. Strengthening immune function

A strong immune system is the key to a long life and to protecting physical health. The antioxidant and anti-inflammatory properties of EGCG support immune function and help protect against infections and diseases that can shorten life expectancy.

How to take advantage of the benefits

Did you know that green tea is a staple in Okinawa? This is not surprising when you consider that Okinawa is one of the “Blue Zones,” i.e. places with the highest density of people who live to 100 years in good health. Green tea consumption could play a role in their exceptional longevity. To benefit from EGCG's longevity benefits, you should drink a few cups of green tea daily. If you are considering taking supplements, you should seek advice from a doctor to ensure safe and appropriate use.

EGCG is a remarkable compound with potential longevity benefits ranging from supporting heart health and weight management to protecting brain function and reducing inflammation. So enjoy a comforting cup of green tea and sip your way to a longer and healthier life.
