What CoQ10 does
CoQ10 is a substance that is naturally present in the human body, with the highest levels in the heart, liver, kidneys, and pancreas. It has been studied for a range of conditions with largely inconclusive or unsupportive results: it has not been shown to be of value in treating cancer (though it may reduce the risk of heart damage from one type of chemotherapy drug), and the few studies on preventing heart disease and on heart failure are inconclusive, while there is some evidence it may reduce the risk of some complications of heart surgery. The overall scientific evidence does not support the idea that CoQ10 reduces statin-related muscle pain, the available evidence suggests it probably doesn't have a meaningful effect on blood pressure, and it did not improve symptoms in early Parkinson's disease; research on ALS, Down syndrome, Huntington's disease, and male infertility is too limited for any conclusions to be drawn. — per the NIH National Center for Complementary and Integrative Health; not medical advice.
What the evidence shows for CoQ10
Studies of CoQ10 for preventing heart disease and for heart failure have been inconclusive, and the overall evidence does not support that CoQ10 reduces statin-related muscle pain or meaningfully affects blood pressure; there is some evidence it may reduce the risk of certain complications of heart surgery — per the U.S. National Center for Complementary and Integrative Health (NCCIH).
CoQ10 — safety & side effects
No serious side effects of CoQ10 have been reported; mild side effects such as insomnia or digestive upsets may occur. — per the NIH National Center for Complementary and Integrative Health.
CoQ10 — interactions & cautions

When and how to take CoQ10
CoQ10 is fat-soluble, so take it with a meal containing fat for much better absorption. Take it in the morning or afternoon rather than at night, since it can be mildly energising.
Can you take CoQ10 with other supplements?
CoQ10 can slightly reduce the effect of warfarin, so keep intake consistent and tell your clinician if you take it. Statins lower the body’s own CoQ10, which is why it is often taken alongside them.
General guidance on timing and absorption, not medical advice. Check with a clinician about your medications and conditions.
