Swanson's **Ubiquinol** delivers 200mg of CoQ10 for heart health and cellular energy — a high dose that sits squarely in the 100–300mg clinical range. You're getting the reduced, active form your body uses directly, with no conversion step needed, sourced from Kaneka, the ubiquinol used in most of the published research. The flaxseed oil softgel helps it absorb, since CoQ10 only works well taken with fat.

At 200mg, this is more than everyday maintenance calls for — it's aimed at people who genuinely need the higher end. If you're over 40, your body makes and converts its own CoQ10 less efficiently, so the ubiquinol form is worth it at that age. And if you're on a statin, those drugs lower your CoQ10, which makes a dose this size useful rather than excessive. For general support without those factors, 100mg would cover you just as well.
