I take quercetin daily for MCAS and as an antioxidant. The idea is to have it continually available for the body to use, not as response to an acute incident. For that, I use Benadryl.
"Quercetin, Inflammation and Immunity" https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4808895/Thank you everyone for your responses. I'm still unclear how many days or weeks does it take to build up in your system so you see the affect of it? How long does it take for it to work? Thank you if you have some idea.
