Green tea (Camellia Sinensis) is a plant frequently steeped in hot water and drunk as tea. It exerts most of its benefits through water-soluble polyphenols (frequently referred to as catechins) extracted from the leaves, into water, which is then consumed.
It has been implicated in benefiting almost every organ system in the body. It is cardioprotective, neuroprotective, anti-obesity, anti-carcinogenic, anti-diabetic, anti-artherogenic, liver protective and beneficial for blood vessel health. These beneficial effects are seen in doses present both in green tea itself (as a drink) as well as from a supplemental form.

|Goes Well With
Quercetin (for increasing bioavailability, and preventing cancer of the lung and kidneys)
Fish Oil (for increasing bioavailability and reducing beta-amyloid pigmentation buildup in the brain)
Curcumin (for protection from colonic tumors)
Vitamin C (for general anti-oxidation)
Butylated Hydroxyanisole (increases Green Tea's anti-microbial properties)
Caffeine and Ephedrine (increases fat burning potential)
Capsicum Vanilloids (highly synergistic for some anti-cancer effects)
Green tea catechins (and other tea components (theaflavins)
L-Theanine (possibly alleviates cognitive decline)
The metabolite of CoQ10, CoQ9, in regards to enhancing anti-oxidation potential
Inositol Hexaphosphate (colon tumor prevention)
Most doses are standardized against EGCG. Although the amount of EGCG-equivalent varies from one cup of tea to another, depending on many factors (species of tea, length of steeping, time spent oxidizing), one cup of camellia sinensis green tea contains approximately 50mg of EGCG-equivalent.
The benefits of green tea catechins on lipid oxidation and related fat-burning pathways are achieved in a dose dependent manner. Significant effects in humans are noted only at high doses, such as 400-500mg EGCG equivalent per day (most Green Tea Extract supplements are roughly 50% EGCG). Fat burning effects are highly synergistic, almost dependent, on not consuming caffeine habitually.
Cancer prevention effects are quite dose-dependent, and would be better to consume all catechins (as green tea extract) rather than isolated EGCG. Minimal doses would be good (200mg or higher) but with more frequency (3+ times a day). High, frequent doses may make one prone to nausea.
