Research in people with heart disease risk factors has shown that consuming green tea extract for four weeks can reduce blood sugar levels and improve gut health by lowering inflammation and decreasing "leaky gut."
Researchers said this is the first study assessing whether the health risks linked to the condition known as metabolic syndrome, which affects about one-third of Americans, may be diminished by green tea's anti-inflammatory benefits in the gut.
In the new study, green tea extract also lowered blood sugar, or glucose, and decreased gut inflammation and permeability in healthy people—an unexpected finding.
"What this tells us is that within one month we're able to lower blood glucose in both people with metabolic syndrome and healthy people, and the lowering of blood glucose appears to be related to decreasing leaky gut and decreasing gut inflammation—regardless of health status," Bruno said.
Participants consumed gummy confections containing green tea extract rich in anti-inflammatory compounds called catechins for 28 days. The daily dose equaled five cups of green tea.
Results showed that fasting blood glucose levels for all participants were significantly lower after taking green tea extract compared to placebo. Decreased gut inflammation due to green tea treatment in all participants was established through a reduction in pro-inflammatory proteins in fecal samples. Researchers also found that with green tea, participants' small intestine permeability favorably decreased.
Gut permeability, or leaky gut, enables intestinal bacteria and related toxic compounds to enter the bloodstream, stimulating low-grade chronic inflammation.
"That absorption of gut-derived products is thought to be an initiating factor for obesity and insulin resistance, which are central to all cardiometabolic disorders," Bruno said. "If we can improve gut integrity and reduce leaky gut, the thought is we'll be able to not only alleviate low-grade inflammation that initiates cardiometabolic disorders, but potentially reverse them."

It doesn’t appear to be just pure EGCG from green tea.
It said it is the equivalent of 5 cups a day of green tea. So I imagine anyone who likes tea could do that amount. Caffeine may or may not be an issue, but coffee or cola has more caffeine.
We on blood thinners are warned not to drink green tea.
Green Tea is okay, but the natural taste is so...blah.
If there are that many benefits I may use a bag of that along with my Oolong Tea, which gets to the point of flavor more quickly.
I’ve got a cousin who’s a green tea nut. He’s always telling me about how healthy green tea is. But he doesn’t take the extract. He drinks green tea, the kind you get at a grocery store. There’s 40 grams of sugar in a 12 ounce bottle.
I think he’s missing the bigger picture here.
It is that pesky 1% that makes them all look bad.
ChiComs trying to manipulate the price of tea in China.
EGCG is also an ionophore for zinc.
Analysis of vitamin K in green tea leafs and infusions by SPME–GC-FID
“In all analysed infusions the concentration of vitamin K was lower than the detection limit of the developed method, however, the concentration of vitamin K1 present in tea leafs was between 120 and 625 μg/100 g.”

Watch Out for Vitamin K?
“It is true that dried green tea leaves have a very high concentration of vitamin K, but a cup of brewed green tea provides only a small amount, 0.03 mcg per 3.5 fluid ounces (roughly half a cup). In fact, research published in the Journal of the American Dietetic Association in 1995 showed that tea is not a significant dietary source of vitamin K and, as you know, green tea provides lots of other health benefits.”

I like oolong, from time to time, but prefer black to to it.
Frankly, I really like tea.
A cure for leaky gut? I’ll have to listen to local am radio this weekend where everything cures leaky gut.😆

890 mg catechins. Not too sure what that means, but FWIW....
Thank you.
A review of adverse event (AE) data from 159 human intervention studies yielded findings consistent with toxicological evidence in that a limited range of concentrated, catechin-rich green tea preparations resulted in hepatic AEs in a dose-dependent manner when ingested in large bolus doses, but not when consumed as brewed tea or extracts in beverages or as part of food.The safety of green tea and green tea extract consumption in adults – Results of a systematic review- snip -
In summary, the present systematic review revealed that green tea is safe across a wide range of intakes and preparations. Under certain circumstances, there is a consistent relationship between green tea preparation in solid dosage form, GTE concentration and constituent level consumed as bolus doses and under fasting conditions and gastrointestinal irritation and liver injury. While there are limitations due to heterogeneity in the identified studies, the findings are quite consistent between animal toxicology and human intervention data. The results of the present analysis, combined with the previously published report from Dekant et al. (2017) suggest that the composition of green tea preparations that most closely reflects that of a traditional infusion is safe. Preparations based on concentrated extracts, containing high levels of individual constituents, such as EGCG, and consumed in solid dosage form, may require health-based guidance values to assure their safe use. Considering hepatotoxicity as the critical effect, for adult individuals with normal liver function, a safe intake limit of 338 mg EGCG/day (in a fed or fasted condition) delivered in solid dosage form (derived in the present review or the previously published conservative limit of 300 mg/day) might be considered. An OSL of 704 mg/day for an EGCG equivalent dose (fed or fasted) might be considered for a green tea preparation consumed in beverage form.
I had the bad 1% for about six weeks.
Be careful with using capsules. Only use them for like two weeks then give yourself a break. Carefully read the directions on the bottle.
If you want the health benefits, you basically have to stick to pure matcha, the way it is prepared in the Japanese tea ceremony, though getting it fresh usually means ordering it shipped from Japan.
(Full disclosure: “chajin” means a person of the tea ceremony; this chajin is a registered instructor in the Omotesenke school of tea, though I haven’t had any students in years, due to having been caregiver to my late wife.)
You said leaky gut. Ha ha ha ha ha!
Green tea decreases levels of fibrinogen and decreases oxidation of lipids. It prevents clotting, which is why it might be a bad addition to blood thinners. On the other hand, if green tea was already consumed regularly by someone being tested for administration of a blood thinner, it might not be a problem. But ask your doctor for proper advice on that.

But I also saw the same reference you mentioned, ConservativeMind. Looks like green tea does not have enough vitamin K in it to concern us. Thanks!
[I’m *not* a doctor or medical professional of any kind, but I like to read and imagine that I’ll become some kind of healthy PT animal again.]
