EGCG and Multiple Sclerosis study concludes: "Thus, a natural green tea constituent may open up a new therapeutic avenue for young disabled adults with inflammatory brain disease by combining, on one hand, anti-inflammatory and, on the other hand, neuroprotective capacities."
EGCG and Alzheimers, University of South Florida EGCG study finds that "A new generation of dietary supplements containing pure EGCG may lead to the greatest benefit for treating Alzheimer's disease." Dr. Tan said humans would likely need 1500 to 1600 mg of EGCG daily to approximate the injection dosage that benefited the Alzheimer's mice. That dosage has already been studied in healthy human volunteers and was found to be safe and well tolerated."

Relentless Improvement's Chloroform-free EGCG Green Tea Extract is a high-potency standardized extract of green tea, high in epigallocatechin gallate (EgCG), believed to be the key phytonutrient in green tea, responsible for its health benefits. The labels of most green tea extracts exaggerate the number of cups of tea represented in their capsules by comparing the product to poor-quality teas.

EGCG Customer Feedback
"I spoke with you in the past regarding my interest in EGCG because my Mother has chronic lymphocytic leukemia (CLL). My Mother has been taking four capsules of EGCG for approximately three months and today she saw the hematologist and her WBC count decreased approximately 24%.
Prior to this my Mother's WBC had doubled in approximately ten months (her WBC went from approximately 32,000 to 65,000). I am so grateful for the great news! The hematologist told us that with this disease WBC will fluctuate BUT my Mother's WBC were on the rise for ten months prior to beginning the EGCG. The hematologist encouraged my Mother to continue taking EGCG and she most definitly will do so."
"Hello,
I have just completed a clinical trial at Mayo Clinic that involved Green tea extract pills containing high concentrations of EGCG. I was in the cohort that was instructed to take 800 mg twice a day. I had absolutely no symptoms when taking this for over 6 months and actually saw my White cell count drop as a result.
Now that my part in the study is completed I have been given the option of taking 6 months worth of Green tea from Matsui. Unfortunately, the 100 mg tablets from Matsui are a NEW formulation of EGCG. They consist of a "paste" inside of a hard shell instead of a capsule with powder that I took when I was on the phase 1 study. I am absolutely unable to take these pills in any amount. I had developed a bad case of gastroenteritis and had extreme stomach pain and cramps after just a couple weeks taking 1600 mg/day. I am now looking for a new EGCG high concentrate pill supplement to take and I ran into your company using a Google search and have ordered 3 bottles."
Related Research of EGCG Green Tea Extract
Research in experimental animals has found green tea or its extracts to be effective against chemically-induced cancers of the lung, breast, colon, liver, and skin, as well as a variety of gastrointestinal organs, cancers induced by chemical carcinogens; more excitingly, green tea extracts have been found to protect animals from existing, spontaneous prostate cancer. More important to us is the human evidence for the health benefits of green tea consumption. Extensive epidemiological evidence shows that people consuming high amounts of Japanese sencha green tea live longer, develop less cancer, have healthier cholesterol levels, suffer less cardiovascular and liver disease, and may be less susceptible to heart attacks.
The evidence for the cancer-fighting powers of green tea is so strong that human clinical trials of green tea powders and extracts are now under way at the Memorial Sloan-Kettering Cancer Center and at other clinical centers in the United States.
How Much EGCG?
If you're looking to use green tea for longevity and to guard against age-related disease, it only makes sense to get the best-backed dose of the best-backed molecule. Indeed, it's these kinds of doses - 800 to 1600 milligrams of EgCG per day that are being used in the human clinical trials that have begun in the last few years.
The Caffeine Conundrum and EGCG
Green tea contains very little caffeine compared to coffee - but of course, it can still add up if you start drinking ten cups of the steaming brew a day. And indeed, one clinical trial which has been using ground tea solids as its drug has reported significant side-effects - including insomnia, fatigue, confusion, nausea, diarrhea, stomach pain, and in even vomiting - linked to the substance's caffeine content.
Some green tea supplements are fully decaffeinated to avoid any such problems however these supplements are inherently less effective than real tea, because several studies have found that caffeine itself plays a significant role in the cancer-fighting powers of green tea.
And there are other benefits to moderate intake of caffeine, despite the clear negative impacts of being a full-fledged caffeine junkie. For instance, large body of research now suggests that modest caffeine consumption reduces your risk of developing Parkinson's disease - probably as a result of caffeine's ability to modulate adenosine A2A receptors in the brain. Another example: green tea polyphenols and caffeine synergize to increase the body's thermogenic fat-burning activity - effects with important implications for the Battle of the Bulge, which is an engagement important for health and vanity alike.
Thus, rigorously eliminating the caffeine content from green tea - whether you get it in cup or capsule - is not the best strategy for your long-term health. While a zero-tolerance approach may be the only way for a few extremely caffeine-sensitive individuals to get the benefits of EgCG, most people will be better off getting at least a little caffeine in with their green tea. Lightly-caffeinated green tea extracts provide a happy medium between caffeine-induced side effects and the loss of significant health benefits.
EGCG Wrap-up
So getting the full benefits of green tea turns out to involve taking a lot of factors into consideration. Green tea extracts should be HPLC standardized to their content of EgCG. They should make it convenient to get 1500 milligrams of EgCG a day, to match the strong epidemiological evidence of health benefits in Japanese sencha drinkers. And they should contain at least a little caffeine, so that the often-synergistic interactions between EgCG and caffeine can be unleashed. Put it all together, and you'll have squeezed a remarkable amount of health benefit into a few small capsules.
