The body produces CoQ10, also known as coenzyme Q10, needed for the functioning of cells. The compound increases energy for cell growth, improves the immune system and acts as an antioxidant to inhibit the destructive effects of oxidation. CoQ10 levels may decrease as people age or because of certain conditions that include heart disease, diabetes and cancer. Some prescription medications may lower levels of the compound. Some research suggests CoQ10 intake through supplements or diet may benefit people with certain conditions, according to MedlinePlus, though more research is needed.
Reduces CoQ10 Deficiency
Some people suffer from CoQ10 deficiency from metabolic disorders, lack of dietary CoQ10 intake or the body using too much of the compound. Intake of CoQ10 shows promise in treating the deficiency through CoQ10 supplements, vitamins and minerals that produce the compound and increases of CoQ10 in the diet, according to MedlinePlus.
Lowers Blood Pressure
CoQ10 may result in a small reduction in blood pressure. Low levels of CoQ10 have been found in people with high blood pressure, but a positive link has not been determined, MedlinePlus notes. The supplements may help maintain blood pressure levels in people with diabetes, which contributes to high blood pressure. Because CoQ10 may lower blood pressure, however, people with low blood pressure or who take blood pressure medications could suffer the effects of lower levels.
Inhibits Cholesterol
People with high cholesterol often have low levels of CoQ10, according to the University of Maryland Medical Center. Cholesterol-lowering drugs called statins may also deplete the body of CoQ10. CoQ10 supplements, however, have been found to prevent the depletion without interfering with the drugs' ability to lower cholesterol levels.
Improves Heart Condition
The cell producing and antioxidant properties of CoQ10 may help prevent and treat heart disease. CoQ10 supplements for heart attack patients may make them less likely to have chest pain and subsequent heart attacks, the UMMC says. CoQ10 may also help improve heart function and reduce oxidation damage in patients recovery from bypass surgery, heart transplantation and other heart surgeries.
Shrinks Tumors
CoQ10 supplements may shrink tumors, reduce pain and result in partial remission for women with breast cancer. Studies of the supplements on these women, however, also included vitamins C and E and selenium, which may have contributed to the improvements, the UMMC notes.
Lowers Blood Sugar
The compound may lower blood sugar levels. People with diabetes or hypoglycemia, also called low blood sugar, need to be cautious when considering CoQ10 intake, monitoring blood sugar levels carefully.
Mild Side Effects
Mild and brief side effects may occur with CoQ10 intake such as nausea, vomiting, heartburn, diarrhea and loss of appetite, the UMMC says. Other side effects may include headache, dizziness, insomnia, skin rash or itching, increased sensitivity to light, flu-like symptoms and fatigue.
