PQ10, a derivative of coenzyme Q10, is known for its role as an antioxidant, supporting mitochondrial function and energy production. Mitochondria, the powerhouse of the cell, are crucial for cellular energy metabolism, and their dysfunction has been linked to numerous diseases, including neurodegenerative disorders, cardiovascular diseases, and metabolic syndrome. PQ10 has been shown to enhance mitochondrial biogenesis and improve cellular respiration, making it an attractive candidate for therapeutic development.
