CoQ10 has the potential to have positive effects on your heart health. For example, it could help reduce high-sensitivity C-reactive protein, an inflammatory marker that can help predict your risk of heart disease.
Researchers discovered that people with heart disease who took a CoQ10 supplement for 12 weeks experienced a decrease in high-sensitivity C-reactive protein. The supplement dosage ranged from 30mg to 300mg a day, with the median dosage being 175mg per day.6
CoQ10 has also been shown to be helpful for heart health in terms of damage to the heart. It might prevent heart damage that certain chemotherapy drugs, such as doxorubicin, may cause.
A review of six past studies showed that people with migraine who took a CoQ10 supplement for three months experienced improvements in their headaches. While the severity of their headaches didn't subside, the length of their headache attack shortened. They also experienced fewer headaches compared to those who took a placebo.
Fibromyalgia is a condition that causes pain throughout the body as well as fatigue and sleep problems. CoQ10 has the potential to decrease pain, fatigue, and morning tiredness in patients with fibromyalgia. Even the depression and anxiety often associated with the condition may be improved with supplementation. One study found that CoQ10 can significantly improve most pain-related outcomes by 24% to 37%. This reduction in pain could also help improve the quality of life and daily functioning for people with fibromyalgia.
Erectile dysfunction is when you have a problem getting and keeping an erection. A study that included 230 people found that CoQ10 supplementation may help with erectile dysfunction (ED). These individuals also had hypertension, or high blood pressure.
Controlling blood sugar (glucose) and insulin levels is an important part of preventing and managing diabetes. CoQ10 might help keep those levels in check. For example, it has been shown to help control blood sugar and improve cholesterol levels in people with type 2 diabetes.
A review of 40 past studies showed that CoQ10 reduced both fasting glucose and fasting insulin levels. CoQ10 also reduced HbA1C, which is your average blood sugar over the last three months. Among all the studies, the doses ranged from 100mg to 900mg a day. The supplement was used anywhere from four weeks to six months.
