The FDA has not approved Coenzyme Q10 (CoQ10) for any medical condition. However, it is widely available as a dietary supplement over-the-counter and is advised by both general care physicians and specialists. Because of its role in ATP production, CoQ10 has an impact on the performance of all cell types, particularly those with a high energy demand, making it vital for the health of all body tissues. This review was designed to emphasize on the CoQ10- chemistry, pharmacokinetics, signaling pathways, pharmacological potentials and mode of action behind diverse their activity. Coenzyme Q10 is also called as ubiquinone with a 10-isoprenoid-unit side chain. Some animals' kinetic curves for coenzyme Q10 developed additional peaks between hours 7 and 24 after drug administration. Over the course of 48 hours, 8.3% of radioactivity in the urine was recovered, consisting of a mixture of conjugated and unbound metabolites, tentatively recognised as Q acid I and Q acid II [2,3 dimethoxy-5-methyl-6-(30-carboxypropyl)-1,4-benzoquinone] in free and conjugated forms, respectively.
