3 years ago I had a stroke. I was 45 years old and the Doctor prescribed vitamins over medicines that could potentially have serious side affects. CQ10 was one of my prescribed vitamins. I have to take one everyday and have not found a better product in my price range. Very thankful I am able to take the vitamin I need without breaking the bank! Thank you.

We use this product every morning along with the rest of our vitamins/medicines. It is easy to take, and we (my husband and myself both), feel that it has helped our joints as well as overall health and that is why we continue to take it and will continue to take it!!

I'm 69 years old and I know that heart health is important at any age, but more so as we age. I know that the medical community is divided concerning the benefit of taking COQ10 daily. However, they all seem to agree that there is no harm, but the overall benefit is still debated. Therefore, I gave it 3 stars because I have no solid evidence that it helps my heart, but I take it anyway in the event that it is indeed furthering my health objectives. Before taking COQ10 I had no heart problems and this was confirmed by an echo cardiogram. I have no exercise restrictions.

[This review was collected as part of a promotion.] I've been taking CoQ for several years and swear by it. After the first few weeks, I noticed that my decision-making abilities and thinking processes were clearer, which has continued. Also, when I go to the doctor for a physical, my blood oxygen is consistently at 99%.

[This review was collected as part of a promotion.] I work for a large pharmacy chain and began using store brand CoQ10 as my father passed from heart failure. At the recommendation of my pharmacist I tried Qunol. Within a week my energy level jumped a and I never felt better. Now I recommend through experience.

[This review was collected as part of a promotion.] I take one a day. I have friends who three a day of a cheaper brand and they can't tell if it works. I shared mine with another friend who wasn't feeling well. He felt "awake" more after about an hour. Love it!

[This review was collected as part of a promotion.] I have been taking Qunol Ultra CoQ10 for three years and have noticed a considerable increase in my energy level every day. Before I would lose stamina around four to five p.m. each day. Now, as I grow older (55), I have increased energy to do the things I want to do with my family on into the evening. My wife and family thank you Qunol and so do I!

I have taken Qunol daily for several years and noticed a difference in my stamina right away. I may do without some supplements, but not Qunol. I am 70 years old and know that CoQ10 is important for heart health. I look and feel younger than most 70 year olds i know. This reviewer received a sweepstakes entry for posting this review.

[This review was collected as part of a promotion.] I take it because I'm on some heart medicine and have been taking it off and on mostly on for the last 5 years. I haven't noticed any negative side effects but I have no way to qualify that it has been of a benefit. That is why I am off and on with it. I wish there was a test to indicate that it's actually helping my health. I do take the garlic and fish oil tablets also so it is difficult to determine whether it is useful or not. It is expensive so I always debate on whether or not I should take it. If anybody knows of a quantitative way to determine that this is actually helpful and what sort of blood test I need to take to determine that that would be great.
