Coenzyme Q10 is an important supplement that can benefit numerous conditions, especially heart disease. CoQ10, as it is often called, supports energy production in our cells and works as an antioxidant to protect our cells from damage. These roles are important for heart health because the heart needs a lot of energy. In addition, the ability of CoQ10 to prevent the oxidation of cholesterol may help protect us from atherosclerosis. CoQ10 is also used to reduce fatigue in patients with fibromyalgia. It can help protect the kidneys and liver. One month of CoQ10 supplementation was even shown to reduce symptoms of dry mouth, probably by improving the functioning of the salivary glands. CoQ10 is even thought to reduce some of the symptoms of old age. In a study with middle-aged mice, those who had received regular CoQ10 showed reduced signs of aging and improved activity levels.
So where does ubiquinol fit into this picture? There are actually two forms of CoQ10, known as ubiquinone and ubiquinol. Most CoQ10 is ubiquinone, the oxidized form of the molecule, while ubiquinol is the reduced form. This means that ubiquinol is the form of CoQ10 that is ready to neutralize antioxidants. Even more important is that ubiquinol can be up to 3 times more absorbable than the standard ubiquinone form. This varies because our body seem to change how much it absorbs based on how much CoQ10 we need. For instance, people with congestive heart failure usually need more CoQ10. In a recent study among this patient group, taking an average of 450 mg of ubiquinone resulted in blood levels of CoQ10 around 1.6 micrograms per milliliter, but when they switched to an average of 580 mg of ubiquinol, their blood levels jumped to 6.5 micrograms per milliliter. Even more importantly, the switch to ubiquinol resulted in improvements in their symptoms. So even though ubiquinol is more expensive than the standard forms of CoQ10, you can get more for your money by buying this more absorbable form.
