Ubiquinone natural sources
Antioxydant mitochondrial essentiel à la production d'énergie cellulaire.
Coenzyme Q10 (CoQ10), also known as ubiquinone, is a fat-soluble quinone that serves as a critical electron carrier in the mitochondrial electron transport chain and a potent lipophilic antioxidant. It is naturally sourced from foods like organ meats and produced endogenously, but supplementation is used to support cellular energy production, cardiovascular health, and to mitigate statin-induced side effects. The primary active forms are ubiquinone (oxidized) and ubiquinol (reduced), with ubiquinol being the more bioavailable antioxidant form.
CoQ10 functions primarily as an electron carrier in Complexes I, II, and III of the mitochondrial electron transport chain, facilitating ATP synthesis. It also acts as a membrane-bound antioxidant, scavenging reactive oxygen species (ROS) and regenerating other antioxidants like vitamin E. In the context of statin therapy, CoQ10 supplementation may counteract statin-induced depletion of endogenous CoQ10, thereby reducing myopathy and improving mitochondrial function. Additionally, CoQ10 modulates endothelial function by enhancing nitric oxide bioavailability and reducing oxidative stress in vascular tissues.
