You're getting 100mg of **Coenzyme Q10** per softgel — right at the floor of the clinically studied range (100–300mg) for heart health and cellular energy production. The softgel uses olive oil as a carrier, which helps since CoQ10 is fat-soluble and needs dietary fat to absorb properly. There's also 5mg of **Black Pepper Extract** (piperine), which can boost absorption of fat-soluble compounds.

The form here is ubiquinone, which your body needs to convert into ubiquinol (the active form) before it can use it. That conversion becomes less efficient as you age, so if you're over 40, you may get more out of a ubiquinol-based product. For younger adults, ubiquinone at this dose is a reasonable starting point for cardiovascular and energy support.

At 100mg you're at the low end of what's been studied — most heart health trials use 200–300mg daily. If you're supplementing for a specific cardiovascular goal, you'd likely want to double the dose to two softgels per day.
