Pharma Nord Bio-Quinone Q10 Gold 100mg Coenzyme Q10 has been suggested as an essential cofactor of enzymes involved in the energy process. Coenzyme Q10 is stored in mitochondria, structures found within cells responsible for the generation of energy (in the form of a molecule called ATP). Tissues with a high-energy requirement (heart, liver, skeletal muscles) contain higher numbers of mitochondria within their cells. Coenzyme Q10 is also important within the body as a major fat-soluble antioxidant, protecting cell membranes from the damaging effects of free radicals, in a complementary manner to vitamin E. Coenzyme Q10 may promote healthy cardiovascular function, and healthy immune function (cells involved in immune response have a high energy dence). Please note that results may vary.
