Studies suggest that CoQ10 may boost the immune system, and it may be an effective secondary cancer treatment, states WebMD. People with certain types of cancer often have low levels of CoQ10 in their blood, leading scientists to believe CoQ10 can help with treating cancer; however, the National Cancer Institute rates evidence of its efficacy in treating cancer as weak, as of 2015.

Although CoQ10 is often associated with treating heart failure, there is little definitive evidence to suggest that it is an effective treatment, as of 2015. It should be used alongside other treatments and not on its own, notes WebMD.

Possible side effects of CoQ10 include headaches, rashes, nausea and sensitivity to light. Some people may experience irritability, heartburn, upper abdominal pain or fatigue, according to WebMD. Taking too much CoQ10 in a day causes mild insomnia in some people. Because dietary supplements are not FDA regulated, they should be taken with caution and only as directed by a health care professional. Some people may have an allergic reaction to CoQ10.
