Bioflavonoids for Herbal Supplementation "My family started taking a once daily, 800 mg quercetin/165 mg bromelain capsule, along with 1000 mg vit c (lypospheric) sachet, and a zinc powder as a prophylactic. After a couple of weeks, it became apparent that our energy levels were reduced, and we became listless, and dare I say, mildly depressed, having no inclination to do anything during the holidays. My wife also experienced headaches. We stopped the Quercetin, and within a few days, energy levels seemed restored, and we feel a great deal more energetic. This may be unrelated to Quercetin, but I felt it worth mentioning, so you may monitor your own feelings."

Bioflavonoids for Herbal Supplementation "I was put on a popular natural antihistamine for sinus allergies and other symptoms of higher histamine levels as I'm entering menopause. The product contains quercetin as a main ingredient. After three days of use, I'm feeling very sick. On and off upset stomach, woozy head/headache, greater fatigue, and overall feel ill all over. I'm fairly reactive to things and have a sensitive stomach. I'm stopping the supplement and going back to my 1/2 Benadryl at bedtime."

Bioflavonoids for Herbal Supplementation "I began taking Rutin after reading that it helps activate brown fat to burn the more harmful white fat (in the belly and elsewhere). For many years, I have taken Ester-C, 500 mg, daily, to which I have added the 500 mg Rutin complex. Because I did not heavily research this OTC supplement beforehand, I did not know it had other uses. By coincidence, I had suffered my first bout with high blood pressure beforehand, and I had also suffered for three weeks with another middle-aged first: a hemorrhoid. After taking Rutin for 10 days, I had no more high blood pressure episodes, no more hemorrhoid discomfort, less knee pain, and fewer asthma symptoms. These benefits were unexpected. The downside? I now have 4 weeks of daily headaches and blurred vision."

"Quercetin was recommended to assist with mast cell activation and histamine intolerance. Be careful if you have complex health issues such as inflammation, cardiovascular, and mental health conditions. After one dose, the supplement caused a surge in heart rate, limb aches, gut disturbance, headache, and adrenaline-related anxiety (intermittent) and muscle tension. To counter these unexpected side effects, required an antihistamine, acetaminophen, and beta blocker to regulate the effects of this supplement. It is not suitable for all. Check with a doctor before taking any online supplements."

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