Thank you for sharing the science behind EGCG. As a nurse and tea specialist I’ve been singing its praises for years and have written about it often. For those who haven’t acquired a taste for matcha, it’s so simple to add to a glass of orange juice or smoothie in the morning. I’ve even added to my espresso! The liver concern with high doses in capsules is real and I’m glad you highlighted that. Beware of where you buy your capsules.

Bravo Dr Marik, for this excellent information about green tea and Matcha!

I read that glucose and glutamine (l-glutamate) are fuel sources for cancer cells.  Learning that green tea and matcha can inhibit glutamine (l-glutamate) is news to me!

Dr. Christina Parks, PhD, a cellular and molecular biologist, advocates using EGCG (green tea) and vitamin C to treat Mycoplasma pneumonia, alongside other therapies.  She says the polyphenol found in green tea has known anti‑inflammatory, antioxidant, and immunomodulatory properties

Bravo back to you. Thanks.

Glutamine even the supplements that are good for the gut?

Cancer & Metabolic Healing's avatar

If you have cancer.. STOP glutamine.

Colleen's avatar

You have a good question for Dr. Marik. I suspect people with cancer would be wise to stop taking glutamine supplements.

I am not a medical professional and am not qualified to offer medical advice. Dr. Marik is the smart one!

Yes. STOP glutamine supplements

Thank you for this detailed review. I owe you a debt of gratitude for much of your work over the past few years including the FLCCC. In addition your personal conduct and professional reorientation of your work is so inspirational. Thank you so much.

Thanks for the support. Greatly appreciated.

I have to agree with Debbie. Thanks so much.

This is a fascinating overview. I especially appreciated the distinction between drinking green tea as part of daily life and using concentrated extracts, where dose and liver safety matter.

As a Japanese reader, I smiled at the matcha section — but the mechanisms here are what make the piece linger after the smile.

hank you my friend. Welcome to my world.

Deb's avatar

I follow your root protocol and added Japanese matcha tea every day. Thank you for the detailed info and research. Allows me to exhale even more.

Breathing is good. You should do it every day. Paul

Is matcha’s high oxalate content a concern?

Cancer & Metabolic Healing's avatar

I dont think so unless you have a history of kidney stone. Make sure you are adequately hydrated.

Thanks, Doc. I’ve been using green tea as a standard of proper nutrition for a long time. Food is medicine, and when used appropriately produces long term benefits, as you teach. Life style coaching used to come from societal norms, parents and Grandparents. However, with libertine lifestyles also comes disease. Folks need to get back to the Bible, Christian principles, and wake up. Relying on treatments and cures as an answer to lousy life style choices is not a wise replacement for prudence and knowledge. All bad choices lead to poverty, death and disability. All good choices lead to health, peace and prosperity. Thanks for educating the folks, Doc, i.e. prompting them to choose green tea instead of enriching the death dealing soda pop perps. They, along with Pharma, are getting wealthy killing us AND our kids. Don’t support their efforts, is my plea to the folks. Thank you, Dr. Marik, for taking the flak from them, and doing right. God bless you.

When taking as matcha tea whats dose comparing supplement to tea? ie how many cups of matcha (1/2 teas spoon tea) = supplement?

Thanks!

Cancer & Metabolic Healing's avatar

The recommendation is up to 4 cups of Matcha tea a day; Calculation below,

Typical Matcha Content

A standard serving using:

½ teaspoon matcha powder contains approximately:

60–120 mg of EGCG

Typical EGCG Supplement Dose

Most EGCG supplements provide:

200–400 mg EGCG per capsule

Approximate Equivalence

Therefore:

1 cup matcha (½ tsp) ≈ 60–120 mg EGCG

2–4 cups/day ≈ roughly equivalent to a modest EGCG supplement dose.

Thank you. Very helpful.

Thanks, of to have tea

I am working with an excellent naturopath, who has advised me to NOT use ECGC while on capecitabine, as it can turn this particular chemo agent toxic. So I am off it while on chemo, and use it when not.

Cancer & Metabolic Healing's avatar

Okay makes sense. It is always a good idea to check drug interactions with chemo drugs.

Fain Zimmerman's avatar

I put a teaspoon of the powder in a smoothie every other day. Is that enough?

Thank you!

Are you familiar with Donnie Yance’s work? He would be good to have on the IMA webinar.

Cancer & Metabolic Healing's avatar

Yes, I know of him. He is the founder of the Mederi Centre for Natural Healing in Ashland, Oregon. We see things very differently… also he is running a commercial enterprise .. always a Big Red Flag.

So appreciate a principled man helping us understand how to take care of ourselves.

Thank You, Dr. Marik. I will include this in my next blog post and have forwarded it to 2 friends, who it might significantly benefit.

Stan Burman's avatar

Thank you, Dr. Marik for this fascinating article about EGCg and green tea.

It’s pretty easy to find EGCg supplements. I am taking one (1X per day) that contains 400 mg of Green Tea Extract (Standardized Extract) [min. 80% Total Catechins and 50% EGCg (Epigallocatechin Gallate) (200 mg)].

But is drinking green tea best? You mention Matcha tea. Is this a brand or kind of tea? And do you know if it’s available in a decaffeinated form.

Thank you so much for all you do.

Sue Johnstone's avatar

is it suggested to take some of the EGCG dose in the evening due to the VEGF circadian connection?

Cancer & Metabolic Healing's avatar

That’s fine. I take my twice a day in the am and then at night.

Michelle's avatar

Does it need to be taken separately from other repurposed meds or supplements?

Cancer & Metabolic Healing's avatar

No.. you can take with all the other meds and supplements..
