Hello, I found some informations about an antioxidant called quercetin. I found that quercetin has anti inflammatory effect.

Related to lung health, quercetin has potential effect in mice. Here is the link.

Quercetin research is now being conducted in human, I found the link: https://clinicaltrials.gov/ct2/show/NCT01708278

Quercetin can be found in some foods, however I think the quercetin content in food is a little bit low.. I'm interested in consume the supplement, but afraid about the safety.

Have you ever heard about quercetin? Thank you for your comments.
