CoQ10 is a fat-soluble nutrient and research has demonstrated better absorption of CoQ10 when delivered in oil. Co-Q-10 contains 100 mg of pure CoQ10 in each capsule, with rice bran oil added to facilitate absorption. CoQ10 has two major functions in the body. First, it is an extremely strong and cellular protecting antioxidant. Secondly, CoQ10 is utilized within the mitochondria to actually make cellular energy. Thus, CoQ10 is concentrated in the brain and heart tissues since these are such energy dependent organs. This makes CoQ10 very important for heart and brain health. ANYONE taking a statin drug like Lipitor, Zocor, or Crestor has to take CoQ10 since these drugs significantly reduce CoQ10 tissue levels. If you are concerned with memory issues, dementia, or any neurodegenerative disease CoQ10 is a must.
