Benefits of Kirkland Signature CoQ10

Coenzyme Q10 is a powerful antioxidant. It can increase absorption of other essential nutrients. It helps recycle vitamin C and vitamin E, to aid these nutrients already at work in the body. The body has the natural ability to make Coenzyme Q10 on its own, although production declines as we age.

It is at this time when we need our cells to help defend us most, and we really need to consume more CoQ10 naturally from within our diet, and by taking a CoQ10 supplement. Furthermore, taking certain prescription drugs like statins may also reduce your body’s natural levels of CoQ10. By taking a high-quality CoQ10 supplement (like Kirkland Signature’s CoQ10), you can support your body’s production of coenzyme Q10.
