For Herbal Supplementation "My NMD suggested Quercetin to me at a dose of 500mg 3 times a day. I only have taken 500mg once a day. This stuff gave me bad side effects of mild dizziness, mild nausea, and difficulty sleeping. I am sensitive to many supplements, so this is not a condemnation of Quercetin for all, but beware, this stuff can cause side effects and make you feel lousy!"

For Herbal Supplementation "Started taking an immunity-boosting supplement today with 200 mg Quercetin. After an hour, had nausea to the extent that I thought I would lose my breakfast, but it passed. Will try again tomorrow. Everything except Q I’ve taken before, so I’m suspicious."

For Herbal Supplementation "Had to stop. Heart palpitations, headaches, nausea, and sleeplessness. Took me a while to realize it was the Quercetin."
