Previous studies have shown that out of all the medical conditions associated with low CoQ10 levels, hyperthyroidism is associated with the greatest deficiencies. In his article on CoQ10, Peter Langsjoen, MD, explains that CoQ10 deficiency is increased in hypermetabolic conditions. Other researchers have noted that the muscle weakness characteristic of hyperthyroidism is caused by low CoQ10 levels. Low CoQ10 levels are harmful to all of the body's muscles and can cause cardiac and pulmonary dysfunction. A link has also been made to cancer, and CoQ10 has been used in studies as a treatment for breast cancer.
A recent study published in the journal Cancer Epidemiology, Biomarkers and Prevention shows an association with low CoQ10 levels and a greater risk of breast cancer in women. Researchers at the University of Hawaii examined data from the Shanghai Women's Health Study and discovered that there was a 90% greater risk of breast cancer among one-fifth of study participants who had the lowest levels of CoQ10. Several research studies have also linked low CoQ10 levels to periodontal disease.
While CoQ10 blood levels are not routinely tested, the lowest levels are seen in hyperthyroidism and in patients using statin cholesterol-lowering agents. An FDA announcement released today advised against high doses of Zocor and other statins because of muscle damage. In many countries, CoQ10 is added to statins to help correct these deficiencies and prevent muscle damage. Patients with hyperthyroidism should consider the use of CoQ10, which is also beneficial for eye muscles, presumably helping to reduce symptoms in TED.
