Coenzyme Q10 and Parkinson's disease
Kathrynne Holden, MS, RD

A number of Parkinson centers have been studying the effects of Coenzyme
Q-10 (CoQ10 for short) on people with PD; the results of the study have
now been published. The study indicates that people in early stage PD, not
yet using Sinemet, who used CoQ10 were able to delay the disabling effects
of PD longer than those in the control group (who did not use CoQ10).

That does not mean CoQ10 is a cure, nor that people will feel any
different if they take it -- just that it may (or may not) slow the
progression of neuronal cell death. The amounts of CoQ10 used in the study
were 300 mg, 600mg, and 1200 mg per day. Those using the highest amount
were able to slow progression of disability the longest. However, while
hopeful, the study was too small to be conclusive. Many people,
understandably, have questions about whether to take CoQ10, and if so, the
kind and amount to take, and whether any adverse side effects are
possible.

What is CoQ10?
CoQ10 is an antioxidant, manufactured in the human body, and also present
in small amounts in some foods -- unsaturated oils, fish, meats and nuts.
As we age, we produce less CoQ10; and it would be difficult to get a
significant amount from foods.

Some disease states tend to use up the body's store of CoQ10, and research
is ongoing as to whether supplements of CoQ10 could be beneficial. It has
been used to treat certain heart conditions, such as congestive heart
disease; and also for patients with chronic renal failure and periodontal
disease.

Medications and CoQ10 -- Interactions
Some medications may interfere with the action of CoQ10 or perhaps
decrease its production in the body. Such medications include "statins",
some diabetes drugs, and other medications. Many doctors now routinely
prescribe supplements of CoQ10 for their patients who are taking
cholesterol-lowering statins including lovastatin (Mevacor), simvastatin
(Zocor), and pravastatin (Pravachol), and the dietary supplement
Cholestin.

It's also possible that some oral diabetes drugs (glyburide, phenformin,
and tolazamide), beta-blockers (propranolol, metoprolol, and alprenolol),
phenothiazines, tricyclic antidepressants, methyldopa,
hydrochlorothiazide, clonidine, and hydralazine may create a need for
CoQ10, but this is not firmly established. If you are considering use of
CoQ10 you should first discuss this with your doctor.

And there is a single report that CoQ10 interfered with the medication
warfarin (Coumadin), an anticoagulant. People using warfarin should not
take CoQ10 without first consulting their physician.

How much CoQ10 is safe to take?
The typical recommended dosage of CoQ10 based on various past studies is
30 to 300 mg daily; however, the recent PD study used amounts up to 1200
mg per day. Do not take such a large amount without first consulting your
doctor. If you do take supplements, it's best to take these in divided
doses, two or three times a day, rather than all at once.

What's the best form to use?
CoQ10 is fat soluble; the oil-based soft gel is better absorbed than dry
tablets or capsules. Because it can "auto-oxidize" -- become a free
radical itself -- it's also best taken with 30 IU vitamin E. It appears
that CoQ10 and vitamin E work synergistically (better together than
separately). Some products contain both CoQ10 and vitamin E in the same
pill. Some softgels that have passed Consumer Lab testing include:

Nature Made 100 mg
Nature's Bounty Q-Sorb 50 mg
Vitamin World Naturally Inspired 75 mg
Q-Gel Plus Coenzyme Q-10 30 mg Plus Alpha Lipoic Acid and Vitamin E
Another product, used in research studies, including studies of
Parkinson's disease, is Vitaline CoQ10. It has not been tested by Consumer
Labs; however, the manufacturer states that it has been shown in studies
to be safe and well tolerated.

Side effects.
There appear to be few adverse effects associated with the usual amounts
used in studies -- 30 to 300 mg per day. Some reported side effects
include stomach upset, loss of appetite, nausea, diarrhea. People taking
CoQ10 late at night have reported insomnia. Amounts greater than 300 mg
per day have been accompanied by increased levels of serum lactic
dehydrogenase, and/or serum SGOT, a liver enzyme.

Studies on the safety of CoQ10 have not been conducted on women who are
pregnant or breastfeeding, or on children, and these individuals should
not use CoQ10.

CoQ10 Buyers Club
A gentleman on the forum, Dan Halligan, has researched the various
brands of CoQ10 and has started a buyer's club, to purchase quantities
of high-quality CoQ10 at the lowest possible prices. If you wish to

Dear Listfriends, the following may be of interest, Best, Kathrynne

Study Suggests Coenzyme Q10 Slows Functional Decline in Parkinson's
Disease

Results of the first placebo-controlled, multicenter clinical trial of the
compound coenzyme Q10 suggest that it can slow disease progression in
patients with early-stage Parkinson's disease (PD). While the results must
be confirmed in a larger study, they provide hope that this compound may
ultimately provide a new way of treating PD.
