For Dietary Supplementation "I practice cycling on a regular basis (200 miles a week) and started taking CoQ10 because it's supposed to make your muscles produce more energy, but I've been feeling sluggish for a week now. The first day I felt tired, I thought it was regular fatigue and rode easy for 4 days, but I still feel sluggish and without the energy that I always have in my rides. I've seen reviews of people that cause them to feel tired, and maybe that is what CoQ10 is causing me. I will stop taking it and will come back to post again."

For Dietary Supplementation "I had taken this religiously 10 years ago at fairly high doses. It really gave me energy. Older now, having developed a lot of sensitivities, I tried it again for fatigue and found it actually made me more tired and dizzy. I stopped the supplement and got better, then tried it again and had the same symptoms. A powerful lesson for me that supplements can have very different effects on different people depending on their physiology."

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."
