My DO recommended taking CoQ10 and it has really helped me feel better. It has really reduced my leg cramps. This is a great buy!

It is recommended that it be taken with a fat containing meal so I took this with my evening meal. I don't need to take this every day but when I do it is very good. Some other reviewers have mentioned about the black pepper fruit extract. I have not had a problem with it.

Have HEALTH ALEART FOR CUSTOMERS OVER 25: Don’t waste your money on this product. Buy the best value for money and best selling fully reduced ubiquinol (Product Number: HOG-36467 or HOG-36469) instead

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.
