Some reviewers’ very informative reviews prompted me to conduct my own Internet search on ubiquinone vs. ubiquinol. I did find the same comment made by Dr Mercola (“If you're over 25, you should use the reduced ubiquinol formula to help you absorb the CoQ10 you need.”). The following statements are from Wikipedia: Coenzyme Q10 (CoQ10) exists in three redox states, fully oxidized (ubiquinone), partially reduced (semiquinone or ubisemiquinone), and fully reduced (ubiquinol). The antioxidant action of ubiquinol is now considered to be one of the most important functions in cellular systems. Ubiquinol is the antioxidant form of CoQ10 and is essential for mitochondrial synthesis of energy. It is the only known lipid-soluble antioxidant that is endogenously synthesized, protecting biological membranes against lipid peroxidation as well as regenerating other antioxidants such as Vitamin C and Vitamin E. Published clinical and experimental research shows that ubiquinol affects cardiovascular health, neuronal metabolism, renal health, and genes related to lipid/lipoprotein metabolism and inflammation. Since the ubiquinol form has two additional hydrogens, it results in the conversion of two ketone groups into hydroxyl groups on the active portion of the molecule. This causes an increase in the polarity of the CoQ10 molecule and may be a significant factor behind the observed enhanced bioavailability of ubiquinol. Orally, ubiquinol exhibits greater bioavailability than ubiquinone: 150 mg per day of ubiquinol in a softgel resulted in peak blood values of 3.84 mcg/ml within 28 days.

I have only started taking the Doctor's Best, CoQ10 3 days ago and no noticeable change yet but will update this review in 4 weeks time. I like the fact that the ingredients are enclosed in a non-toxic capsule. The product did arrive in Australia about the time specified on the iHerb.com website; much to my relief since it was my first order with the company. It is now been 8 weeks. My health has improved; sleeping better and without having to get up during the night. I also have a healthy color to my facial skin. I must add that I am also taking LifeExtension Grapeseed Extract.

My pulse was 100 over per minute. I took this for a week and it has slowed down to 80 plus. :) I took 2 caps per day for 1 week and subsequent weeks i change to 1 cap per day.

The Caps are easy to take; either whole; or opened up and sprinkled onto morning cereal with milk & yogurt. I have noticed that my fingers are not nearly so sore, and I can also straighten them out without pain.

Side effect of taking CoQ10 that can occur with some people is getting rashes. I`ve had on my face and under the arm pits so I will likely not continue with this.
