This **Coenzyme Q10** delivers 500mg per capsule for cellular energy and heart support, well above the 100–300mg range used in most clinical research. That puts a single capsule comfortably past standard maintenance dosing. A dose this high makes the most sense if you're on a statin (which depletes your CoQ10), managing heart failure symptoms, or want aggressive mitochondrial support — for everyday energy upkeep, 100–200mg usually does the job. Take it with a meal containing fat, since CoQ10 is fat-soluble and absorbs poorly on an empty stomach.

One thing to know about the form: this is ubiquinone, the oxidized version your body has to convert into active ubiquinol before it can use it. That conversion slows after about age 40, so if you're older you may absorb more from the ubiquinol form — though the sheer 500mg here helps offset that gap.
