Coenzyme Q10 (CoQ 10) or ubiquinone is essentially a vitamin or vitamin-like
substance. Disagreements on nomenclature notwithstanding, vitamins are defined
as organic compounds essential in minute amounts for normal body function acting
as
coenzymes or precursors to
coenzymes
Coenzyme Q10 is made in the body and found in almost all cells, but levels decrease
as we age. It's also found in most foods, though in tiny amounts. That's why some
experts advise those older than age 40 to take
coenzyme Q10 supplements.
Additional benefits of the CoQ10 supplementation include : reducing the blood pressure, controlling abnormal heart rhythms, preventing atherosclerosis in the arteries and alleviating congestive heart failure (CHF)
. Studies have shown that supplementation of CoQ10 improves conditions of
91% of heart attack patients within 30 days. 9, 10,
In addition, CoQ10 levels in the body directly affect our immune system. Studies have shown that persons infected with HIV and have low CoenzymeQ10 levels in their body, progress more rapidly to full-blown Acquired Immune Deficiency Syndrome (AIDS) than persons with optimal levels. 6
CoQ10 helps slow the brain aging process and aids in preventing neuron damage that leads to Alzheimer's disease. Reversal of this mental deterioration through supplementation of CoQ10 has been documented in several studies. In addition studies have shown a high dosage of CoQ10 can help treat Parkinson disease. 7, 8
Does Coenzyme Q10 have any side effects?
No serious side effects have been reported from the use of CoQ10.Some patients that used CoQ10 have experienced mild insomnia, elevated levels of liver enzymes, rashes, nausea and upper abdominal pain.
University of Maryland studied the various drugs which deplete CoQ10.These can be seen in the Table 1.
