Your body makes Coenzyme Q10 (CoQ10), a fat-soluble compound that sits inside every cell. It helps mitochondria turn food into energy and acts as a built-in antioxidant. Natural production tends to drop as you get older.
People take CoQ10 to support heart function, lift cellular energy, and speed exercise recovery. Others pair it with statin drugs to keep muscles feeling normal.
Take it once or twice daily with a meal that contains fat. Fat helps your body absorb it. CoQ10 can interact with blood thinners like warfarin. A few people notice mild stomach upset or trouble sleeping.
