Memory improvement
34 people found this helpful
We decided to give Ubiquinol to our mother for her congestive heart failure. What we didn't anticipate was the improvement in her short-term memory, a symptom of her dementia. Previously, she had been stabilised on Aricept for two years. However, after a year on Co-Q 10, her memory has significantly improved. This unexpected benefit was truly remarkable.

Heart function support

This important supplement strengthens heart muscle function. After two recent hospitalisations, I had to stop taking it for a few weeks, leading to the development of congestive heart failure. However, it resolved shortly after resuming Jarrow ubiquinol at a daily dose of 400 mg, in divided doses.

Boosted energy
9 people found this helpful
Ubiquinol from this brand truly works! It’s a fantastic supplement, especially for women planning a healthy pregnancy. It also significantly boosts libido. I recommend ubiquinol over ubiquinone since it absorbs much better into the body and stays in the bloodstream longer. After switching, I felt a surge of energy and marked improvement in my health. It benefits the elderly and heart patients taking statins too.

Jarrow's CoQ10 products have been part of my routine for five years due to heart problems. I take 100mg doses 1-3 times daily for effective results. Smaller doses of CoQ10 are ineffective. I always find the best prices and service at iHerb.

Remarkable heart effect
1 people found this helpful
I find the absorption rate of Jarrow Formulas satisfactory. When feeling overly fatigued, I take a dose, and within half an hour, I notice a significant relief in heart pressure and shortness of breath. This product has made a notable difference for me and my elderly relative on kidney dialysis.

Stops heart palpitations
3 people found this helpful
Since starting the 200mg Ubiquinol a month ago, my heart palpitations, which I have dealt with for years potentially due to being vegetarian, seem to have halted. I will continue with the 100mg as I believe it to be an effective supplement.

Essential for heart health
For heart health, this is essential for anyone on statin medications, which I am not. Nonetheless, I take it daily for heart health. It's a very reputable company, so I feel assured in purchasing from them.

Supports heart health
2 people found this helpful
Kaneka's Ubiquinol is fantastic! Compared to ubiquinone, it is absorbed more effectively, supporting both cardiovascular health and energy. Its superior absorption makes it particularly beneficial for heart health, especially in older adults who find it easier to utilise than standard Coenzyme Q-10.

Essential for heart

After 20 years of taking Ubiquinol, I can confidently say it's the best price for a quality product vital for my heart health. At 75 years old and off all medications, I switched from CoQ10 to this 100mg product, taking it twice daily with meals.
