I took this suplement for one week and I had headaches two hours after. When I stopped, I felt better. No results for me.

I'm not aware of any other fully vegetarian CoQ10 supplement at this strength. Great product!

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.
