Matcha antioxidants: What are they and why do they matter?

Is matcha high in EGCG? What green tea has the highest EGCG?

You’ve probably heard of ceremonial matcha- the green tea best known for its bold green colour and grounding umami taste- but did you know that this powerful Japanese tea is considered one of the best sources of EGCG (epigallocatechin gallate) antioxidants? 

 Green tea and matcha come from the same tea family, but they differ in terms of their taste, quality and their antioxidants - the powerful compounds responsible for many of the health benefits associated with drinking green tea.

Green tea antioxidants: Green tea vs Matcha vs Ceremonial matcha

Green tea: Is commonly available as loose leaves, tea bags, or powder. Created using only part of the tea leaf, its associated health benefits come from polyphenol antioxidants. 

Matcha: is a powdered form of Japanese green tea loved for its distinctive green colour and umami taste. Made using the whole tea leaf, it delivers its health benefits via EGCG antioxidants and L-theanine catechins.

Ceremonial matcha: The highest grade of matcha, treasured for its vibrant green colour and superior umami taste. This matcha tea uses shade-grown leaves, making it the green tea with the highest level of EGCG antioxidants. It is this form of matcha that we use to ensure that Ancient + Brave’s Ceremonial Matcha + Collagen provides more antioxidant units than an entire pack of blueberries or spinach!

EGCG and catechins: Matcha’s evidence-backed antioxidants explained 

So, what are these antioxidants, and why do they matter? 

Catechins are a type of polyphenol, which are natural antioxidants found in plants. Various studies have shown that they have benefits for human health, including neutralising free radicals to help protect against cellular damage.

EGCG is the acronym used for epigallocatechin gallate, the most powerful of all the catechins. It's unique to green tea, and especially concentrated in matcha, thanks to the way matcha is grown and prepared. 

You see, unlike other teas, matcha is made from whole, powdered green tea leaves, so you’re consuming the entire leaf rather than just steeped extracts. 

Here’s a summary of the science-backed benefits of this remarkable matcha antioxidant:

• Fights free radicals and helps protect cells from oxidative damage

• Supports metabolism and healthy weight regulation

• Enhances cognitive performance and reduces neuroinflammation

• Promotes skin health by reducing UV damage and improving elasticity

• Reduces chronic inflammation, a key contributor to ageing and disease

Ceremonial-grade matcha: Your antioxidant powerhouse

These incredible benefits for whole-body health are one reason why we’ve upgraded our Matcha + Collagen ritual with ceremonial matcha from Uji, Japan.

Carefully crafted to bring you a superior umami taste alongside unrivalled antioxidant benefits, this energising rise ritual now delivers more than a 10% increase of EGCG.

*Please note, when we say our ceremonial matcha contains 9,440 ppm of EGCG, we’re talking about concentration - specifically, how much EGCG is present in a given amount of matcha powder. 

Evidence-backed matcha: Inside our antioxidant testing process

And don't just take our word for it.

As part of our ongoing commitment to bringing you the purest, most effective wellbeing rituals,  we commissioned independent lab testing with Knight Scientific to benchmark the total antioxidant capacity of our Ceremonial Matcha + Collagen powder. 

Using Singlet Oxygen Quenching Antioxidant Testing, a robust test that simulates oxidative stress in the body, our lab results revealed a high score of 2,773 ABEL-RAC™, validating Ceremonial Matcha’s polyphenol density, antioxidant capacity, and evidence-based benefits. 

These scores indicate high antioxidant capacity, which means that every serving of Ancient + Brave’s Ceremonial Matcha + Collagen provides more antioxidant units than an entire pack of blueberries or spinach. After all, your trust and your well-being deserve nothing but the best.
