Written by Allison Tannis, Author of Aging Bites

From brighter, younger-looking skin to witty wellness as you age, scientific research shows antioxidants, particularly epigallocatechin gallate (EGCG), promotes longevity and helps you age well. Fresh, green tea leaves contain abundant amounts of (EGCG). Here’s everything you’ll want to know about how to use this natural ingredient for anti-aging, including a helpful look into 8 amazing ways scientific evidence shows EGCG promotes longevity.


8 Amazing Ways EGCG in Tea Leaves Delays Aging

Scientific studies have found EGCG in tea leaves promotes longevity in many ways, including:

  • Anti-inflammatory
  • Rejuvenates Skin Cells
  • Improves Structure of Skin
  • Lowers Proteins that Age Skin
  • Promotes Longevity Factors
  • Helps Gut Microbiome
  • Benefits Immune System
  • Helps with Blood Sugar




Does EGCG in Fresh Green Tea Leaves Delay Aging?

If you’re feeling old, let’s talk about it – and what you can do to delay aging. It’s simple – eat more leafy greens. To be specific, fresh tea leaves! Let’s explain: there are a number of factors that influence how fast the body ages. Inflammation is  one such factor. Inflammation is destructive and when it’s constantly happening, aging happens faster. Many adults live with low levels of inflammation from stress, processed foods, lack of sleep, and exposure to environmental pollutants. Thousands of studies have looked at the anti-inflammatory effects of nutrients from around the world and the natural ingredient with some of the most exceptional abilities to promote longevity is EGCG.


EGCG in tea leaves stops inflammation, which helps delay aging.


How Does EGCG  Delay Aging?

Over a cup of tea or green smoothie with friends, you’d say EGCG delays aging by triggering longevity factors in the body. In geeky scientific terms, one would explain the antioxidant EGCG seems to turn on longevity factors (Fox03a and SIRT1), which have the ability to stop the NF-kB, which would otherwise wreak havoc by turning on inflammation.



EGCG prevents wrinkle formation and helps skin cells rejuvenate.




Does Green Tea Reduce Wrinkles?

Wrinkles tell stories of a life well-lived, but there’s a difference between healthy and unhealthy aging of the skin. EGCG is a well-known antioxidant. Anti-aging abilities of EGCG include preventing the formation of wrinkles and rejuvenating skin cells. In research studies, EGCG appears to improve the structure of the skin, reduce the presence of inflammation, and lower levels of proteins known to play a role in skin aging. That’s firmer, more youthful-looking skin!  


Studies show people who drink green tea are less likely to develop dementia.


Drinking Green Tea Lowers Risk of Dementia, Says Studies

In populations of people who tend to drink green tea often, there are lower rates of dementia. As such, researchers took a closer look at EGCG’s ability to promote longevity in the brain. Evidence suggests that EGCG helps activate nerve cells in a way that helps your brain age well. Plus, the brain benefits from theanine and arginine found in tea leaves, which have a stress-reducing effect.


3 Ways Eating or Drinking Your EGCG Improves Aging from Your Gut

Down in your gut, there are three impressive ways EGCG improves aging, according to researchers:


  1. EGCG Improves Your Microbiome’s Probiotics.

When EGCG is present in your gut, it beneficially influences the types of microbes there: more good microbes in your gut improved digestion, nutrient absorption, and immune responses, including lower inflammation. EGCG is a polyphenol, which is becoming well recognized by gut scientists as a very helpful nutrients for the probiotics and other helpful microbes that live in your gut.


  1. EGCG Flips the Switch on Aging Genes.

When EGCG is in your gut, it also impacts which genes are expressed. Your genes are recipes for many things: some keep you feeling young and energetic, while others promote inflammation and other aging processes.


  1. EGCG Helps with Blood Sugar.

There’s another benefit of having EGCG in your belly: when you drink a cup of EGCG-rich tea or eat fresh tea leaves, it appears to have beneficial effects on your ability to manage blood sugar – another culprit of aging.


At What Age Should You Drink Green Tea?

You may want to turn on the blender or pour yourself a cup of tea right now! When a group of researchers looked at the mechanisms by which EGCG delays aging, they discovered that despite much research raving about the effects of green tea in the elderly, the benefit to longevity may be peak if EGCG is part of your healthy routine in early- and mid-adulthood. In other words, drinking green tea, or better yet, including fresh tea leaves in your culinary creations, as early as your twenties is a great way to delay aging. Continue to consume these EGCG rich tea leaves for decades afterward and your body will have the tools it needs to age well.

The most potent source of EGCG is fresh tea leaves.

Which Tea is Anti-Aging?

Tea has been touted as a great anti-aging beverage. The science we’ve just covered points towards EGCG as a major promoter of longevity. Where can you find tea leaves with the most EGCG?  Fresh tea leaves contain 15x more EGCG than conventional dried green tea leaves. Millennia Tea offers fresh tea leaves in the frozen section of your favourite retailers.
