Coenzyme Q10 and L-Carnitine, a synergy.
The pair supports complementary stages of mitochondrial energy production, with L-Carnitine increasing fatty acid delivery into mitochondria and CoQ10 improving the efficiency of converting that fuel into ATP.

Synergy
What is happening. The pair supports complementary stages of mitochondrial energy production, with L-Carnitine increasing fatty acid delivery into mitochondria and CoQ10 improving the efficiency of converting that fuel into ATP.
Mechanism. L-Carnitine forms the carnitine shuttle that transports long-chain fatty acids across the inner mitochondrial membrane for beta-oxidation, while CoQ10 carries the resulting electrons through complexes I to III of the electron transport chain to drive ATP synthesis.
Recommendation. Reasonable to take together, with or without food, for fatigue, exercise capacity, or mitochondrial support. Typical doses are CoQ10 100 to 200mg per day and L-Carnitine 1 to 2g per day. A migraine prophylaxis trial used both concurrently.
