Horrible anxiety and panic!
This is just my personal experience with this supplement, you may not have this reaction. After taking this, within an hour I had a horrible redness and burning through my body and face. It's from the niacin, which is TOO high in this supplement. I've had this happen before, but I wasn't worried about it. It's the things that happened after that was concerning and almost made me go to the emergency room. I started to lose sensation of my limbs, till I couldn't feel anything in my legs and arms. My stomach blew up huge, like I was pregnant. I started to sweat, throat closing up, terrible panic attacks and anxiety. Heart rate went up, faint, dizzy. Whatever is in this is POTENT! this lasted 3 hours for me. I've never had this happen with b vitamins before. I recommend that if you are sensitive to maybe stay away from this one. My husband took one and he had the niacin flush and burning, but no other symptoms. So, maybe this will agree with most people, but for me it was horrific and one I will never take again.
