Depletions

Coenzyme Q10

Taking propranolol or metoprolol may deplete coenzyme Q10.

Coenzyme Q10 (CoQ10) is required for the production of energy in your body. It also acts as an antioxidant. It is very rare to be deficient in CoQ10, but some of the symptoms may include:

• Muscle weakness and pain
• Fatigue
• Weakened immune system

Low levels of CoQ10 over a long time may be linked to heart diseases, diabetes mellitus and high blood pressure.

Editorial Note

The information presented here covers some of the nutrients that may be affected when you take certain medicines. If you have any of these signs and symptoms, it does not always mean you have low levels of these nutrients.

Factors that affect the level of nutrients are:

• Your medical history
• Diet
• Lifestyle
• How long you have been taking the medicine

Please talk to your health care provider. They can best address your health care needs and see if you are at risk for low levels of any nutrients.
