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 "I took 500 mg for the first time this morning, for anti-inflammatory properties. Also took it with my normal probiotics and an NAC that I've been taking for immune support. I was hoping for an energy boost and skin benefits as well. This definitely made my heart race a bit, but it didn't last too long. My mother-in-law loves this stuff. Too soon to tell if it's beneficial for me or not. Would like to give it a go again."
