I have taken 150 mg CoQ10 for several years, hoping to give my heart the energy it requires as I age. When I recently discovered your new formula with Ubiquinol I switched over, still adding one of the other at night. Almost immediately I felt more stamina in doing daily chores. I found I could do more in a day and still have energy to walk my dogs in the evening. Hence, I feel younger. I am seventy four, feel more like I did in my mid sixties.
