Research

Heart Health

The heart demands high levels of energy for optimum cardiovascular health, which is why CoQ10 is naturally found in the heart. CoQ10 is an aid in several aspects of heart health; such as preventing cholesterol oxidation, especially in balancing LDL cholesterol levels.

More than 50 million Americans have imbalanced blood pressure levels, which can lead to negative cardiac conditions. Though it may not be the underlying cause, low levels of CoQ10 are often found in people with high blood pressure. Prescription medications for the heart (statins, etc.) further deplete the body's natural CoQ10 levels.

Studies find CoQ10 benefits blood pressure by lowering systolic and diastolic levels without significant side effects.[1],[2],[3] A meta-analysis of 12 clinical trials (362 patients) showed systolic blood pressure could decrease up to 17 mm Hg, while diastolic blood pressure could decrease up to 10 mm Hg with CoQ10 supplementation.[4] Another study indicated 60 mg per day of CoQ10 safely lowered systolic blood pressure by 7.3 mm Hg in twelve-weeks.[5] CoQ10 is even viewed as a safe addition to standard heart treatments.[6]

One study indicated 90 mg per day of CoQ10, in conjunction with 5 gm per day of phospholipids (lecithin) decreased systolic and diastolic blood pressure, along with total and LDL cholesterol in four-weeks.[7]

Supplementing CoQ10 can relieve side effects associated with various heart treatments. A double-blind study found CoQ10 can reduce muscle pain associated with statin drug use. Patients were given CoQ10 (100 mg per day) or vitamin E (400 IU per day) for 30 days finding pain severity decreased by 40%, and pain interference with daily activities decreased by 38% in the CoQ10 group. In contrast, pain was not relieved in the vitamin E group.[8] Another study indicated CoQ10 supplementation improved diastolic function that is often worsened with statin therapy.[9]

Energy

Studies show that CoQ10 aids athletes' energy demands. One study supplemented 100 to 300 mg per day of CoQ10 one week prior to a workload trial. Subjects experienced less fatigue and improved athletic performance during the workload.[10] Another study found supplementing 300 mg/d of CoQ10 decreased exercise-induced muscle injuries among Japanese Kendo athletes training 5 to 6 hours each day.[11]

Supplementing with 200 mg of CoQ10 rapidly restores CoQ10 levels in the muscles and reduces oxidative stress. One study indicated subjects that received an acute dose (one time dose) of 200 mg had a higher CoQ10 muscle concentration and lower levels of oxidative stress in the muscle. The same study found subjects receiving a chronic dose (fourteen-days, 200 mg per day) improved their workout capacity, as they experienced less fatigue.[12]

Neurological Health

Similar to the heart, the brain has a high-energy demand relying on optimal mitochondrial function or cellular energy. Researchers are exploring the benefits CoQ10 on improving energy expenditure in the brain and hindering the effects of neurological ailments. After two months of CoQ10 supplementation (100 to 200 mg per day), energy expenditure in the brain can increase by 29%.[13] A study conducted by the University of California at San Diego randomly assigned 80 patients with early stages of neurological degeneration to receive 300, 600 or 1200 mg of CoQ10 each day, or a placebo. After 10 months of research, the study found that patients receiving the 1200 mg dose had a 44% slower rate of decline, when compared to the placebo group.[14]

Stabilize Blood Sugar

A CoQ10 deficiency can affect an individual's ability to tolerate glucose leading to unstable blood sugar levels. A twelve-week study found that patients with blood sugar imbalances could stabilize their blood levels by supplementing with 200 mg of CoQ10 per day.[15]

Another study found dangerous ketone levels that are associated with unstable blood sugar (excessive ketone levels can lead to blood acidity and unconsciousness) were lowered in more than half of patients that received 120 mg of CoQ10 for up to eighteen-weeks.[16]

Skin Health

CoQ10 is naturally found in the skin with vitamins A, C, and E; but its overall production diminishes with age leaving skin susceptible to oxidative damage caused by free radicals. Research suggests CoQ10 can repair and protect the skin from oxidative damage that accelerates skin aging. In combination with carotenoids, topical CoQ10 has been shown to be a potent anti-inflammatory that is easily absorbed through the skin to discourage premature aging.[17] Along with reducing oxidative stress, another study found topical CoQ10 improves the appearance of the skin by decreasing wrinkle depth.[18]
