[This review was collected as part of a promotion.] I have found no downsides. I like to think it is helping me to keep my heart healthy. I am genetically predisposed to high cholesterol and heart disease. I have made it to 71 years old without any of these issues. I pray the good Lord keeps it that way for a long time. I plan on living to 100 so I can irritate my kids.

[This review was collected as part of a promotion.] I have been taking Qunol Ultra CoQ10 for years just as an extra precaution in my quest for heart health. I had been taking this supplement for years before I was diagnosed with a-fib caused by hypertension and this is the only supplement my doctor permitted me to continue taking. I still have a-fib because it's not curable, but I feel that Qunol if CoQ10 was not good for me in some capacity, my physician definitely would not have let me continue taking it. If my doctor trusts it, then I sure do.

[This review was collected as part of a promotion.] This is my 3rd purchase. I have taken CoQ10 for over 15 years. Tried many different brands. This one by far is the best. Easy to take. Absorption is better than average. Customer service with company is excellent. Love this stuff!

[This review was collected as part of a promotion.] I've had a history of high cholesterol for many years. My primary physician instructed me to take this every day about 13 years ago. This has helped to keep my cholesterol levels well within normal range.

[This review was collected as part of a promotion.] I bought this supplement after listening to David Sinclair, I don't really have heart problems but I've noticed my skin looks much better and fresh, I don't know the science behind it seems to work for me.

[This review was collected as part of a promotion.] Taken in conjunction with my statin meds and recommended by my doctor, Qunol Ultra is the extra protection I need for heart health. This makes my life healthier and easier. I have much greater peace of mind. Thank you, Qunol Ultra!

[This review was collected as part of a promotion.] I was introduced to Q10 by my mother in 1996. I told my doctor I was taken it, along with other supplements, and recommended Qunol, black box, back in 2008. I have been taken it ever since. I appreciate when the box offers 25% more for my money.

[This review was collected as part of a promotion.] I have used this product for 6 months and have found it is as advertised. I am very encouraged that a company produces a broduct that is important for better health and the company advertizing is accurate.

[This review was collected as part of a promotion.] My daughter-in-law told me I should be taking this. She is a nurse in a doctors office, He is a MD and also a Dr of holistic medicine, and this is the one he recomended . I am 80 yrs old and I am in good health and I want to stay that way.

My husband and I have been using this product for years for heart health. We like the fact that it is standardized and has proven studies on superior absorption. We take 100 mg daily as a preventive but increase to 200 mg daily if we are planning to be in areas of high altitude because it helps with acclimation.
