At 400mg in one daily softgel, this **CoQ10** runs well above the 100–200mg most people take for everyday energy upkeep. A dose this high makes the most sense if you're on a statin — which depletes your body's CoQ10 — or you're targeting heart failure support or migraine prevention. The oil-based softgel helps, since CoQ10 is fat-soluble and absorbs best alongside a meal with fat.

The form here is standard ubiquinone, which your body converts to the active ubiquinol form — a conversion that slows after 40. If you're older or want the most absorption per milligram, ubiquinol skips that step; at this high a dose, though, ubiquinone still gets plenty across to support cellular energy and heart health.
