Positive experiences
“The above supplements have worked amazingly for my brain fog and motivation.”
“EGCG (green tea extact) and quercetin may two others to look into. Paired with NMN and 7,8DHF it seems to compound the energy improvements of NMN for me by a lot.”
“Her kidney specialist said up to 500mg quercetin is fine per day, may actually be beneficial...I like NMN, I believe it's best paired with something like quercetin or another cd38 inhibitor for better absorption.”
“Quercetin and bromelain, Vitamin K and D, astaxanthan, fish oil, turmeric, boron, msm, and coq10. I have osteoarthritis and this combo has been helping with the pain.”
“Quercetin. I had it against Covid, but apparently it is also good for allergies. It worked.”
“I feel like it does help against allergies and cold and flu season.”
Negative and mixed experiences
“The Thorne Quercetin has helped me a lot with seasonal allergies. I'd go as far as to say it had been more effective for me than either Claritin or Zyrtec.”
“I like quercetin but had to stop due to joint/tendon pain. I narrowed it down to that. It worked amazing for my mental clarity, energy and allergic rhinitis”
“Quercetin has helped my daily allergy symptoms to the point that I no longer need Allegra”
“Quercetin gives me bad insomnia. Like, night owl energy. I still take it because I am a woman of science and I like to experiment, but the benefits are yet to be realized”
“quercetin makes me uncomfortably wired; definitely could fuel anxiety.”
