Coenzyme Q10 (CoQ10), also known as ubiquinone, is a naturally occurring, fat- soluble, vitamin-like substance found in almost every cell of the body, especially in organs with high energy demands like the heart, liver, and kidneys
. It plays a critical role in the mitochondrial electron transport chain, where it helps convert food into energy by facilitating the production of adenosine triphosphate (ATP), the primary energy carrier in cells
. CoQ10 also functions as a powerful antioxidant, protecting cells from oxidative damage caused by free radicals, which can harm cell membranes, DNA, and lead to cell death. This antioxidant property may help reduce damage related to aging and various diseases, including heart disease and cancer
. Although the body produces CoQ10 naturally, it is also obtained from dietary sources such as meat, fish, and some vegetables, and is available as a dietary supplement
. CoQ10 supplements come in oxidized (ubiquinone) and reduced (ubiquinol) forms, with bioavailability influenced by the formulation and presence of fats during absorption
. Clinically, CoQ10 is studied for potential benefits in heart-related conditions, improving energy production in cells, preventing blood clots, and supporting vascular health by preserving nitric oxide and reducing oxidative stress
. It is also linked to conditions with reduced CoQ10 levels, such as fibromyalgia, diabetes, neurodegenerative diseases, and statin-induced muscle symptoms
. In summary, CoQ10 is essential for cellular energy production and acts as a vital antioxidant, supporting overall cellular health and metabolism
