Question on this Product: Rhodiola Rosea Extract Powder | 60 Grams | 3% Salidroside

I ordered the product in the title line on Amazon from Nootropics Depot (you were the seller), and I noticed that you sell a different Rhodiola extract that does not have Rosavins.
I was wondering if the Rhodiola Rosea Extract Powder that is 3% Salidroside, does not have the Rosavins removed?

1) Yes and no. Technically not without a separate GRAS filing, but many people do it anyway. If you do use those solvents, then you need residual solvent testing to make sure there are none left.
2) Anthocyanidins are a class of things, like polyphenols. They are different in bilberry and blueberry. Just because they are in the same class does NOT mean they are the same thing, or have the same effects.
3) Freeze dried powder is just removing the water content. Based on Examine's estimates, they are saying 50% of the weight is water. An extract is harder to compare. I would have to do some research on the specific extract to really know for sure.
4) Generally yes, as long as you are using a reliable vendor. How tablets are made is they are mixed in a massive batch all together before entableting. So if it is mixed properly, like with a V mixer for a long enough time or a super nice 3D multi-directional powder mixer, then the ingredients will be consistent throughout the tablets. If they are not mixed properly, then you will get hot spots in the powder, where the active is more concentrated. Then your tablets will not be as consistent. So it depends on the competency of the vendor you are using, what equipment they have, and how well they mix the batches for the tablets.
