Potential Health Benefits of CoQ10
Supported by a large body of data, the following list indicates health problems that are associated with CoQ10 deficiency, and where CoQ10 supplementation has been found to be beneficial:

Cardiovascular Disease (CVD)
CoQ10 has an important role as an antioxidant in maintaining cardiovascular health by protecting LDL from oxidation.

Hypertension. COQ10 may be all that is needed in mild cases. 46 male and 37 female hypertensive patients (mean age ~70) received 120mg/day CoQ10 in a study by the Department of Veterans Affairs Medical Center in Boise, Idaho. Systolic blood pressure was reduced by an average of 17.8 mmHg.

Similar results were obtained by Australian researchers with a daily dose of 200 mg CoQ10 in 74 hypertensive diabetics

Brain cells that suffer continued oxidative stress will eventually die. Oxidative stress causes inflammation, and CoQ10 is a player in reducing the inflammatory marker C-Reactive Protein (CRP) in animals

High dose CoQ10 supplementation has been found protective against neuronal toxins in animal models, particularly in Parkinson's and Huntington's diseases, and also ALS. Also, note that sufficient CoQ10 supports a healthy blood flow from the heart, which provides needed nutrients for the brain.

Parkinson's Disease. Recent clinical trials in these disorders demonstrate that supplemental CoQ10 can slow functional decline. In a large, multi-center study, 80 subjects with early Parkinsons were administered CoQ10 doses of 300, 600 or 1200 mg per day and followed for 16 months. Those who received CoQ10 experienced less disability than those who received the placebo, and the benefit was greatest in those who received the highest dosage

CoQ10 supplementation has been reported to reduce insulin requirements in diabetes mellitus - Australian researchers reported a reduction of HbA1c (an indicator of blood sugar control) in a large group of hypertensive diabetics who received a daily CoQ10 dosage of 200 mg per day.

Healthy individuals have more than a 90% ubiquinol ratio in their plasma, whereas individuals with Type 2 Diabetes have as little as 25% - This decrease correlates to lower energy levels.

Two dramatic case studies published in 1994 confirm CoQ10's role in reducing/removing cancer tumors
(1) A 59-year-old woman who had intraductal carcinoma (cancer) of the left breast, which resolved completely on a daily dose of 390 mg CoQ10
(2) A second patient, after breast surgery, was found to have residual intraductal carcinoma in the tumor bed - She refused additional surgery, and was placed on 300 mg CoQ10 per day. Over a year later, there was no evidence of residual tumor or metastases. Despite practicing oncology for 35 years, over which he had treated about 200 cases of breast cancer per year, one of the authors commented that he had never seen such a spontaneous complete regression of a 1.5-2.0 cm breast tumor on any conventional anti-tumor therapy.

A more recent study indicated that breast cancer is associated with a decrease of plasma CoQ10 levels - and the worse the cancer, the greater the decrease in CoQ10.

COQ10 improves renal function - Dr. Ram B. Singh of the Heart Research Laboratory and Center for Nutrition in Moradabad, India, reported on a new indication for CoQ10 therapy, in a patient with acute glomerulonephritis, renal failure and high levels of lipid peroxides. He administered 180 mg per day of CoQ10, with a resultant lowering of lipid peroxides and significant improvement in renal function.

In a follow-up study of 11 patients with chronic renal failure (serum creatinine levels were 5 mg/dL or above) who were on intermittent dialysis, Dr. Singh again administered CoQ10 at a dosage of 180 mg per day. After 4 weeks of treatment, the patients experienced significant reductions in serum creatinine and blood urea and significant increases in creatinine clearance and urine output, and fewer subjects required dialysis.

CoQ10 is dramatically effective in treating periodontal disease - a common malady of aging. In an early study 8 patients received CoQ10 at 25 mg. twice a day, versus a placebo group. Results showed a reduction in pocket depth with photographic evidence of improved gingival health.
