Effect
of green tea catechins with or without caffeine on anthropometric measures: a systematic review and meta - analysis.
(1) Green tea consumed either as an extract in tablet form (equal to about 400
mg green tea catechins) has been shown to reduce the incidence of the flu among healthcare workers by 75 %.
The European Food Safety Authority (EFSA) has assessed the safety of
green tea catechins from dietary sources, following concerns regarding their possible harmful effects on the liver.
This pure epicatechin extract is at 90 % concentration, derived from natural sources such
as green tea catechin.
It also
contains Green Tea Catechins which has powerful antioxidant properties and helps in improving the effects of caffeine to further enhance the weight loss results.
While green tea catechins refer to up to six catechin molecules, EGCG is the one implicated in fat - burning effects to the largest degree.
Several studies have shown that green tea has antiviral properties; one study found that taking
green tea catechin capsules helped prevent health - care workers from catching the flu, and another found that Japanese schoolchildren who drank green tea for six days a week or more were less likely to catch the flu.
When Sprague - Dawley rats were fed a diet including 148
mg green tea catechins / d for 12 d, fasting plasma glucose and insulin concentrations and the insulin response to an oral glucose load (2 g glucose / kg body wt) were significantly reduced (9).
There is some evidence that long - term consumption
of green tea catechins is beneficial for burning fat and may work with other chemicals to increase levels of fat oxidation and thermogenesis.
Ewa Jówko concluded in her chapter «
Green Tea Catechins and Sport Performance,» published in Antioxidants in Sport edited by Dr.Manfred Lamprecht, that the consumption of green tea catechins — the major component of green tea extract — has been shown to increase fat - burning and energy expenditure, particularly if combined with caffeine.
Fiber is increasingly used as an ingredient for weight management, as is protein, while more specialist ingredients include L - carnitine and
green tea catechins.
The most popular ingredients incorporated for a weight management claim in 2015 were fiber, L - carnitine, chromium,
green tea catechins, protein and citrulline.
The researchers suggest that the hepatitis C virus cell entry was impeded by EGCG acting on the host cell since
the green tea catechin wasn't found to alter the virus particles density.
Green tea catechin plus caffeine supplementation to a high - protein diet has no additional effect on body weight maintenance after weight loss
Features EGCG (
green tea catechins), alpha lipoic acid, cinnamon, and other beneficial nutrients to help support insulin activity and glucose metabolism.
According to one review of 20 studies, a higher intake of
green tea catechins was associated with significantly lower levels of LDL and total cholesterol (72).
Polyunsaturated fats such as fish oils and

green tea catechins, you'll feel radiant and healthy!
Green tea reduces C - reactive protein and
green tea catechins can successfully banish cancer cells, by slowing metastasis, inhibiting cell proliferation and inducing apoptosis.
The compounds responsible for the benefits are thought to be
the green tea catechins (GTC), of which EGCG is the main one.
The doses of
green tea catechins (GTCs) studied is quite high often requiring upwards of 5 - 10 cups per day.
(4) These weight loss phenomena, however, seem to be only unique to
green tea catechins and not in catechins found in other foods.
In 1975, researchers found that
green tea catechins (GTC) blocks COMT, the enzyme that degrades noradrenalin and thus GTC could increase noradrenalin levels and increase energy expenditure.
The researchers found that people who drank about 5 cups of green tea daily, and supplemented with
green tea catechins, had a lower risk of colon cancer recurrence over 10 years.
