An antioxidant. Helps with free radicals and maybe mitochondria. Often taken for aging. Cleans up the mess of how cells produce energy while sick, leading to an increase in energy. “Suggested doses for healthy people appear to be around 100 mg/day. For those under stress and those wishing to receive CoQ10’s possible anti-aging properties, the suggested dose is 200-300 mg/day.

Because ubiquinol is fat soluble, it should always be taken with high-fat meals.” (Health Rising)
