Such interactions across cultures often times can be difficult even in the best of situations. In many cultures, what is considered acceptable interactions in one culture often times translates as inappropriate and rude interaction in another culture.
These catechins are then broken down into four main classifications of: Although all catechins share similar properties, EGCG appears to be most potent in regards to many of them.
These four catechins are the main catechins, although some other isomers or conjugates may be present with either catechin or epicatechin as a backbone, and varying levels of gallic acids. Common sources of green tea catechins primarily the four stated include: Chungtaejeon Tea Korean fermented tea  which has lesser amounts of catechins but a higher anti-oxidant potential 1.
Structure There are five 'catechins' in Green Tea. The parent compound is found in two isomers catechin is the trans isomer, and epicatechin the cis isomerand epicatechin also exists with a hydroxylation as epigallocatechin. Both epicatechin and epigallocatechin can become acylated with Gallic Acid to form gallates.
For the purpose of this article, all five will be referred to as 'Green Tea Catechins'. The two molecules that have gallic acid moeties hanging off the bottom right hand side of the above picture EGCG and ECG share properties that are not seen with the other two EGC, EC, and C ; this is because the gallic acid moiety itself may contribute to structure-function.
Formulations and Variants A combination of green tea catechins and L-theanine called LGNC has been investigated for its ability to improve memory. In one study on patients suffering from non-clinical memory decline average age 58 it shows some efficacy, mostly in increasing recognition speed, word reading, and selective attention.
LGNC is a 6: Flavonoids with a catechol B ring appear to be effective such as rutin, isorhamnetin, and quercetin  and EGCG has an IC50 value of 0. This is due to persons with a low-active genotype of COMT being highly associated with higher serum adrenaline levels at rest and exercise.
NADPH oxidase inhibition can result in both antiinflammatory and antioxidative effects in a manner not related to the catechins directly scavenging free radicals 2.
Absorption Intestinal uptake bioavailability of green tea catechins is low, ranging from 1. They are better absorbed on an empty stomach. Absorption might be able to be increased with piperine, but studies need to be conducted in rats or humans since the animals used, mice, show interspecies differences when compared to humans Green Tea Catechins, primarily EGCG, are inhibitors of intestinal sulfurotransferase enzymes which may metabolize other supplements or drugs.
A higher inter-individual variation exists.
These amounts are the same whether green tea is administered as a pill or via decaffeinated tea. There seems to be a tipping point at around mg, where the amount in the blood then increases more dramatically.
Very high doses of EGCG in the blood are associated with nausea. Learning and Memory Due to EGCG being able to easily cross the blood brain barrier  and at mg increasing brain activity up to 2 hours after ingestion, biological relevance for cognition has been investigated.
Anxiety and Mood In healthy persons, a single dose of mg EGCG was not found to influence mood in a positive or negative manner. Atherosclerosis Supplementation of Green Tea Catechins has been found to reliably increase the presence of catechins in the blood and overall antioxidative potential of the blood    which then leads to a reduction in LDL oxidation.
Blood Flow and Vasorelaxation Green tea consumption whole tea has been reported in a meta-analysis to increase endothelium-mediated vasodilation. A possible mechanism of action may be the green tea catechins' ability to increase Nitric Oxide bioavailability in vivo.
Cholesterol Green tea catechins are potent inhibitors of the enzyme Squalene epoxidase, a rate limiting enzyme that turns squalene into cholesterol. Insulin When taken alongside sucrose, black tea containing Green Tea Catechins at mg does not appear to alter the insulin response in healthy and diabetic subjects  whereas another study pairing brewed green tea mL with a light breakfast found that green tea did not alter the overall exposure to either insulin or glucose when compared to water.
Insulin Sensitivity Studies assessing Green Tea Catechins and insulin sensitivity have found in non-diabetic individuals no significant differences from placebo with both mg EGCG,  a nonsignificant trend towards improved insulin sensitivity in overweight women mL brewed; estimated COMT is an enzyme that, despite being considered the 'main' mechanism of how green tea catechins exert their effects, is present in the pancreas  and implicated in regulation of blood glucose.Table: CPT Codes / HCPCS Codes / ICD Codes Code Code Description; Information in the [brackets] below has been added for clarification purposes.

A TRUE LIFE OR DEATH SCENARIO. On extended dry fasts the first few days are the roughest as the body is still optimistically holding out for food or water but once it figures out that water and food are not coming and that death is imminent if it doesn’t adapt and fast to given circumstance it switches gears into survival mode— this highly adapted state IS the magical key of dry fasting.
