Does it matter whether they use a product standardized to 90%, 95%, or 98% purity? Should be the same in the end as long as the actual amount of Epi is correct? Also, it's really interesting to me that a lot of these companies don't even mention how much Epi they are putting much less what the purity is. Who buys this ****?
Companies play a lot of games with the way they label Epicatechin products and it sucks for consumers that don't understand a lot of the labeling semantics that companies use to trick them.
I go on and on on here about how it bothers me that some companies treat labeling laws like they don't exist - some play deceptive games with labels which is unethical but legal, whereas some others just straight out lie on labels.
I've been meaning to do an article on that subject in general; but here's a quick overview:
Let's take Epi-Plex for example:
The label states:
(-)- Epicatechin - 300 mg.
^^^^ That means that there is 300 mg. of actual Epicatechin per capsule.
In a case like that, it wouldn't really matter the % used because its being identified on the label by the actual active amount, which is 300 mg. So, in a case like that - 307 mg. at 98% is 300 mg., 316 mg. at 95% is 300 mg., or 334 mg. at 90% is 300 mg.
However, let's say that the label said:
(-)-Epicatechin (90%) - 300 mg.
^^^ then in that scenario that would mean there was 300 mg. of Epicatechin raw materials at a 90% purity so that would actually be 270 mg. active.
To a consumer that doesn't know the difference, these things look the same but are different.
Then, let's take another scenario, the dreaded proprietary blend:
______ Ingredient XYZ, Epicatechin, _____ Ingredient XYZ - ___ mg.
^^^ the problem in that scenario is that it could literally be only 1 mg. Epicatechin because by law, a proprietary blend is supposed to be listed from highest dose to lowest dose. So it could really be almost all of the first listed ingredient and then the ones after it could be just for window dressing.
Then, you have another way you see it labeled and that is that you'll see it stated in some way showing Green Tea and in parenthesis, standardized for Epicatechin - and in that scenario you have no idea at all how much Epicatechin is in there or if they're just selling Green Tea bc it would contain a slight amount of Epicatechin in it, trivial, but they're technically not breaking the law.
I hope that all helps and make sense.
