how much quercitan is in a capsule?

There is none. By law all ingredients have to be on the label and how much. It’s not on the label so it means it has none

To stamiron: the i-mask protocol requires 250mg of quercetin. what it the quercetin mg in this?

The quercetin is among several other ingredients which are a combined 350mg. You might want to get one of the other stamiron products that do have quercetin in a higher amount

Where are the ingredients sourced for the capsules ?

All of our ingredients are sourced from the United States of America with the exception of a few globally sourced ingredients that are unavailable in the USA. For example, Turmeric is generally only available in India so it must be sourced from India directly. I hope this helps!

How much quercitan is in this??

It's says it's 350 MG blend of Quercetin, black elderberry, turmeric, ginger root

S**!

Wonderful!

This is the first time that I'm writing a review. I have quite a terrible immune system, but since taking these regularly, I have not been getting sick like I used to, and hardly ever get sick, even when I'm around people who have the flu. This is what I reccomend to my family amd friends to stay healthy! Please keep making these just as they are. God reward you!
