Coenzyme Q10, often called CoQ10, Q10, ubiquinone, or ubidecarenone, is a substance similar to vitamins that’s found in the mitochondria of human cells. It’s vital for producing the body’s energy and is found in high amounts in organs that need a lot of energy, such as the liver, heart, and kidneys. In its reduced form, ubiquinol, CoQ10 is also a powerful antioxidant, which is why it’s a popular nutritional supplement.
### What is Coenzyme Q10 and What Does It Do?
CoQ10 is present in every cell in your body, providing the energy necessary for cell regeneration. This widespread presence explains why it has so many different names. As an energy carrier, CoQ10 goes through various cycles of oxidation and reduction, eventually acting as an antioxidant that combats free radicals which can damage cells. It also helps to regenerate Vitamin E and prevents the oxidation of LDL cholesterol, also known as “bad” cholesterol.
Your body naturally produces CoQ10 throughout your life, but its levels can decline as you get older. Certain diseases, genetic conditions, and some prescription medications can also lower CoQ10 levels. However, you can increase these levels by eating foods rich in CoQ10 or by taking supplements. Foods such as organ meats, healthy oils, nuts, seeds, and vegetables like broccoli and spinach are good sources of CoQ10.
Because of its strong antioxidant properties, CoQ10 is a popular purchase at health food stores and natural food outlets. Many people believe it can boost the immune system and help prevent serious health issues like cardiovascular disease, Parkinson’s disease, and cancer. But CoQ10 supplements are not regulated, and some health professionals have concerns about their safety.
### Are There Any Risks with CoQ10 Supplements?
While CoQ10 supplements are usually safe at low doses, taking more than 100 mg per day might cause side effects like insomnia and digestive issues. Long-term use of more than 300 mg daily can increase liver enzymes. Other potential side effects include headaches, dizziness, heartburn, rashes, and sensitivity to light.
CoQ10 supplements can also interact with a range of medications. For instance, people with diabetes might notice changes in how their body responds to insulin, and those on blood thinners like Warfarin could see changes in their medication’s effectiveness. Individuals taking statins for cholesterol should be particularly cautious, as these drugs can reduce the body’s CoQ10 levels. Over-the-counter medications like aspirin, antacids, and laxatives can also interact with CoQ10.
Special care should be taken when considering CoQ10 supplements during pregnancy or while breastfeeding. Since high-energy organs like the heart need large amounts of CoQ10, those with cardiovascular diseases may face additional risks with high doses of the supplement. It’s always best to consult healthcare professionals before starting any new supplement, especially to understand how it might interact with other medications and health conditions.
### Conclusion
Coenzyme Q10 is essential for the body’s energy production and provides antioxidant protection to all tissues. While supplements can be beneficial for those with low natural levels of the enzyme, it’s important to use them cautiously and under the guidance of a healthcare professional.
