CoQ10 was first identified in 1957. Its chemical structure was determined in 1958. Interest in CoQ10 as a possible treatment for cancer began in 1961, when it was found that some cancer patients had a lower than normal amount of it in their blood. Low blood levels of CoQ10 have been found in patients with myeloma, lymphoma, and cancers of the breast, lung, prostate, pancreas, colon, kidney, and head and neck.
Research about how CoQ10 plays a key role in the way cells make energy was awarded the Nobel Prize in Chemistry in 1978.
Studies suggest that CoQ10 may help the immune system work better. Partly because of this, CoQ10 is used as adjuvant therapy for cancer. Adjuvant therapy is treatment given following the primary treatment to lower the risk that the cancer will come back.
