CoQ10 and Statins: What You Need to Know About Side Effects and Support

When you take statins, a class of drugs prescribed to lower LDL cholesterol and reduce heart disease risk. Also known as HMG-CoA reductase inhibitors, they work by blocking a key enzyme your liver uses to make cholesterol. But here’s the catch: statins also interfere with your body’s natural production of CoQ10, a compound your cells need to produce energy, especially in muscles and the heart. Also called ubiquinone, it’s found in every cell and acts like a battery charger for your mitochondria. That’s why so many people on statins report fatigue, muscle aches, or weakness—symptoms that often improve when they add CoQ10 back in.

CoQ10 isn’t just a supplement for people on statins. It’s naturally made by your body and plays a role in heart health, brain function, and even skin aging. But as you get older, or when you’re on long-term statin therapy, your levels drop. Studies show statins can reduce CoQ10 by up to 40% in some people. That’s not a small thing. If your muscles are sore, you’re tired all the time, or you feel like you’re running on empty even after a full night’s sleep, low CoQ10 could be part of the problem. It’s not just about cholesterol—it’s about energy. And your heart? It’s one of the most energy-hungry organs in your body. Without enough CoQ10, it can’t pump as efficiently.

Some doctors routinely recommend CoQ10 supplements with statins. Others wait until side effects show up. Either way, if you’re on a statin and feeling off, it’s worth asking about CoQ10. The supplement is generally safe, well-tolerated, and doesn’t interfere with the cholesterol-lowering effect of your medication. It won’t undo the benefits of your statin—it just helps your body keep up with the cost.
