Mitochondrial dysfunction is linked to various health issues, including metabolic disorders, cardiovascular diseases, and aging-related decline. Given PQQ’s role in enhancing mitochondrial function and its antioxidant properties, it is increasingly recognized as a candidate for dietary supplementation aimed at improving mitochondrial health. While the body can synthesize PQQ, dietary sources include fermented foods, green tea, and certain fruits and vegetables. Incorporating these into one’s diet may provide the necessary support for mitochondrial function and, by extension, overall cellular health.
