CoQ10 is a key electron carrier in the mitochondrial respiratory chain and an important lipid-soluble antioxidant; depletion reduces cellular energy output and increases susceptibility of membranes and LDL particles to oxidative damage. This medication is commonly used for Hypertension.
Mechanistic and clinical studies link lower CoQ10 status with impaired oxidative phosphorylation and higher markers of oxidative stress, particularly in tissues with high metabolic demand such as myocardium and skeletal muscle.

Some side effects may be linked to nutrient depletion caused by this medication.
Coenzyme Q10 (CoQ10) plays a vital role in cellular energy production. However, our ability to produce CoQ10 naturally declines with age, and dietary sources rarely provide therapeutic levels. Additionally, beta-blocker medications can further deplete CoQ10 stores. Therefore, individuals taking beta-blockers may benefit from CoQ10 supplementation.
