**Coenzyme Q10** at 400mg per capsule — above the usual 100–300mg supplement range — aimed at cellular energy production and heart health. It's delivered in a rice bran oil softgel, which matters because CoQ10 is fat-soluble and absorbs far better in an oil base like this one than in a dry capsule.

This is ubiquinone, the standard oxidized form your body converts to active ubiquinol. That conversion gets less efficient after 40, and ubiquinone absorbs less readily than ubiquinol gram-for-gram — so the high 400mg dose here partly offsets the lower-absorbing form.

A dose this high makes the most sense if you're on a statin, which depletes CoQ10, or you're managing heart failure or using it for migraine prevention, where 200–400mg is typical. For general energy support, 100–200mg covers most people, so you'd be getting more than you need.
