How it works
SARS-CoV-2 and other viral infections impair mitochondrial electron transport chain function, reducing cellular ATP production. CoQ10 is a critical electron carrier in this chain and acts as a fat-soluble antioxidant, helping restore mitochondrial efficiency and reduce oxidative stress that drives post-viral fatigue.
