For Dietary Supplementation "I started taking CoQ10 without any research. After a few days of taking 100 mg, I was ill; diarrhea, cramps, vomiting for over 25 hours straight. Then dizziness and weakness. Now it is the 3rd day. The doctor and I thought food poisoning because of me eating at a buffet. But it just dawned on me to read up on this supplement. I have kidney disease and take thyroid medication. Now, I just want to know how long before I feel better and how long it takes for the CoQ10 to get out of my system?"

For Dietary Supplementation "I started taking CoQ10 because I heard it was important to take it if you were taking a statin. I started feeling very tired and had severe diarrhea lasting for hours. I don't know if it would do anything for my heart, liver, or my migraines because I can't tolerate it."

For Dietary Supplementation "I tried it once because my daughter highly recommended it. After a few minutes, I got 2 bouts of diarrhea, cold hands, and lightheadedness. I ignored the symptoms, and they went away. Then that night, I suddenly felt like passing out, so I checked my sugar level, and it went down to 59, which I had never experienced before with a full lunch. I am so devastated and weak, so I decided to stop the CoQ10. It is potentially bringing my sugar so low and making me pass out. I have to stop this vitamin. It is not working for me."
