Ubiquinol

Ubiquinol is produced naturally within healthy bodies and is found in most tissues. One of Ubiquinol's essential functions is cellular energy production.  Ubiquinol boosts the immune system which leads to greater number and activities of macrophages and TCell/Lymphocytes and greater resistance to infection.

 Ubiquinol has been shown to have antioxidant properties. This protects the cells of the body from various forms of dangerous free radical damage, which can slow aging, prevent brain and heart disease and stop permanent cell damage.  Ubiquinol provides antioxidant protection to DNA.
Ubiquinol is an effective treatment for cardiovascular disease (heart disease) and has been used as a treatment for cancer.  Ubiquinol has indirect anticancer activity through its effects on the immune system.
