As an antioxidant, CoQ10 also protects the cells in the body by neutralizing free radicals, which reduces oxidative stress in the body. Oxidative stress can cause tissue damage, inflammation, and cellular apoptosis, or cell death. There are links between oxidative stress and a range of disorders, including Alzheimer’s disease and Parkinson’s disease.
Naturally occurring levels of CoQ10 decrease with age. Scientists have identified associations between CoQ10 deficiency and heart disease and cancer.
There is currently not enough evidence to support using CoQ10 to either prevent or treat cancer or Parkinson’s disease. However, it might help treat certain heart conditions and prevent migraines.
Researchers have also looked at the effects of CoQ10 on a variety of other conditions, but the results are inconclusive. These conditions include ALS, Down syndrome, Huntington’s disease, and male infertility.
