First, a little background on this interesting organic compound. Co-Q10 is a component of the electron transport chain in the mitochondrial membrane. Mitochondria are the major energy-producing organelles in the cell and thus Co-Q10 has a critical function in the manufacture of ATP, the cells' energy currency. High concentrations of Co-Q10 are found in areas that need the largest supply of energy, such as the heart, liver and immune cells.
Although Co-Q10 can be manufactured in the body, the process involves many steps and the presence of at least eight vitamins. [1] Hence, some researchers think Co-Q10 may be a conditionally essential nutrient under certain health conditions or in people with low levels. For instance, relatively large doses have been used to treat hypertension. [2] Co-Q10 has also been used to reduce the toxicity of certain chemotherapy drugs. [3]
The data on actually treating cancer are exciting but preliminary. Research suggests a relationship between various cancers and the level of Co-Q10 in the blood. [4] One human trial studied the effect of 90 mg/day of Co-Q10 on breast cancer patients. The results showed that after two years, the women who took Co-Q10 lived longer. Because there was no placebo in this trial, the researchers calculated that on standard therapy, a percentage of these women would have died in this time period. With the nutritional protocol, none of them did. [5]
The same research group reported that a few of those women were later given much larger doses of Co-Q10—390 mg/day. In two cases, there appeared to be complete remission of the cancer metastases. [6] It is unclear how these massive dosages may be working, but it may involve stimulating the immune system. [7] Co-Q10 appears to be virtually nontoxic even at these doses. Although Co-Q10 may prove to be a useful nutrient in certain cancer treatments, much more research is needed.
