What to look for when buying Green Tea Extract

Value for money ?

We all want a good quality product at the best price, but the product descriptions are often confusing or inadequate and sometimes misleading.
I hope the following observations will make choosing a product somewhat easier.
I am a buyer, not a seller, so I do not have a vested interest.


EGCG (epigallocatechin gallate) is the important ingredient in green tea extract.
EGCG is a catechin.
Catechins are polyphenols.
The concentrations of each of these varies between products.
e.g.     a quality extract will contain  50% EGCG,    80% catechins,    98% polyphenols.
or ...   a lesser product will contain    15% EGCG,    30% catechins,    40% polyphenols.
It is also important to know how much extract is in each capsule / tablet.
This may vary from 50mg to 500mg.
The seller should give all these figures,  especially  % EGCG  &  mg extract.

So ....   200mg extract at 15% EGCG has    30mg EGCG
             500mg extract at 15% EGCG has    75mg EGCG
or ....    500mg extract at 50% EGCG has  250mgEGCG

What's in the title.

Beware  of descriptions like "High Strength" or "High Concentration" .
Study the ingredients before believing it. 
If the seller doesn't give them they might have something to hide.

Another common misleading description is ....  (example)
   "Green Tea Extract  1000mg"     
Not only would it be difficult to get that much extract in a capsule or tablet but
if you study the small print it will say something like ....
    100mg green tea extract as a 10:1 concentrate, green tea equivalent 1000mg
so you are only getting 100mg of extract,  not 1000mg as per the title.
The title should read   Green Tea Extract 100mg    or    Green Tea 1000mg.

Bear all the above in mind when calculating how much your ECGC really costs.

Thankfully some sellers are now listing the actual EGCG content in mg.
