Klaire Labs Coenzyme Q10 150mg The heart muscle, periodontal tissues, immune system, liver, kidney, brain, and other vital organs require coenzyme Q10 to supply energy through ATP activation and to help protect them from free radicals. Illness, aging, poor nutrient intake, and use of certain medications can result in inadequate endogenous production of CoQ10 to sustain optimal organ function. Coenzyme Q10 as ubiquinone is completely solubilized in natural d-limonene oil, derived from citrus oil, and vitamin E in these convenient softgel formulations. This unique solubilization process assists absorption of coenzyme Q10, a fat-soluble nutrient, by ensuring a source of dietary fat is present. Recommended Use: 1 capsule, 2 times daily with food or as directed by a healthcare professional.
