For Herbal Supplementation "It took a while for me to put it together, but this supplement caused pretty significant heart palpitations and racing heart. The brand I used was by Toniq if that has an effect. I'm sensitive to caffeine in that way, but I do not use caffeine. I didn't use long enough to see a benefit. I figured the connection to heart palpitations after about 10 days. Sorry it took so long."

For Herbal Supplementation "It has taken me much too long to realize I had 7 side effects: palpitations, rise in blood pressure, pounding in my ears, nervousness, heavy legs, dizziness, and blurred vision. I am struggling here, and I don't know how to get relief now. I will never take it again. I am really sensitive to all kinds of supplements and pills."

For Herbal Supplementation "Started taking this after hearing about it from an internet guru. I have a slow heart rate to begin with. This stuff slowed it down in the 40s. I believe many experience dizziness from either bradycardia or tachycardia caused by this supplement. I also had problems sleeping, as well as leg pain. Literally every side effect listed. Don't use this. There are beneficial flavonoids in fruit that won't cause all of this mess."

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