Kirkland Signature™ Ubiquinol provides 200 mg of CoQ10 as Ubiquinol and 30 IU of vitamin E.Coenzyme Q10 (CoQ10) helps support heart function and helps neutralize free radicals in the body.† It is found in nearly every cell of the body and is a key component in cellular energy production.† There are two main forms of CoQ10 in the body – ubiquinone and ubiquinol. Ubiquinol is the major circulating form of CoQ10 in the body, and the form that also provides antioxidant benefits.† Vitamin E also helps support antioxidant activities and is essential to the healthy functioning of many cells, including those in the heart muscle.†

Ubiquinol is a specialized form of CoQ10, that undergoes a patented process to provide an active form of CoQ10 as Ubiquinol. Ubiquinol is the highest form of CoQ10 in the bloodstream. Kirkland Signature provides CoQ10 in the active form, Ubiquinol, to help you meet your body’s CoQ10 needs.

For statin-users

Certain cholesterol-lowering drugs (statins) are known to inhibit the body’s production of CoQ10, which is why supplementation is often suggested for statin users to help replenish CoQ10 levels.¹^,2† Kirkland Signature Ubiquinol is sourced from Kaneka Ubiquinol™. Clinical studies have shown that ubiquinol supplementation resulted in higher CoQ10 blood levels.³^,4^,5

In energy metabolism

CoQ10 is found in nearly every cell in the body and is necessary for the basic functioning of cells.¹CoQ10 exists inside small organelles of the cell called mitochondria, the powerhouses of the cell, where it is needed to generate cellular energy. With CoQ10’s presence in the lining of every mitochondria, we are able to convert food (carbohydrates and fat) into cellular energy. Knowing the role CoQ10 plays in cellular energy production, it's no wonder that the highest concentrations of CoQ10 are found in the hardest working organs, such as the heart, liver and kidneys.†

CoQ10 exists in moderate amounts in meat, poultry and fish and in even smaller amounts in nuts, fruits and vegetables.¹Higher levels of CoQ10 can be found in organ meats like kidney, heart, and liver, while lower levels can be found paired with vitamin E in the germ of whole grains.
