For Dietary Supplementation "The first day I took this, I experienced breathing difficulty, light-headedness, and felt somewhat dizzy. I did not realize it was the supplement causing it. I saw my doctor, and they could find nothing wrong. Day two, the same thing happened shortly after taking it. That's when I researched the product here and discovered the possible side effects, which affected me. My blood pressure was elevated rather than low. I feel fine when not taking this product."

For Dietary Supplementation "I am a heart patient since 5 years and implanted pacemaker since 1 year. I decided to try Coenzyme Q10 for heart health and immunity, etc. I have normal BP 140/70 and sugar under control up to 150 units. My doctor said it is a waste since it does nothing. Good reviews are posted by their own people or promoters. I took it for 5 days. Believe me, I was driven to the ground on the 4th day. My BP went down to 90/60 and my sugar came down to 90. I was dizzy, fainting, and had all sorts of breathing issues and fatigue, cold sweats. My heart was stopping and skipping, etc. I threw the bottle out in my trash bin and I'm back to normal now. Wonder why it is not launched in pharmacies if it was so good. Guys, don't get deceived by the reviews and posts. Don't ever take CoQ10. How can these money-greedy donkeys introduce something that can destroy you? Please pass it on to all you know, and if possible, to WHO and other medical control facilities. Thanks."

For Dietary Supplementation "Bought a 30 mg dose, the smallest I could find. They say to try the smallest dose if you are starting something new. I took mine after a heavy breakfast, which usually makes me sleepy. After just 10 minutes, I felt my heart rate speed up, like a panic attack was coming. I had a little bit of difficulty breathing, as if I was catching my breath from a quick run. I thought it worked like a vitamin, not like an adrenaline injection! Good thing I started with the lowest dose. Scary experience, not sure if I want to take another dose (this was recommended by my doctor for better sperm quality). Stuff works, for sure, but safety? I don't know, man. I'm giving an overall 5/10."

For Dietary Supplementation "Took 1 capsule of Qunol. Following the morning after the second capsule, chest tightness and difficulty breathing. Didn’t seek medical care. Very, very scary. DON’T TAKE this supplement. Please."
