CoQ10 and Sex
Can CoQ10 improve your sex life? I'm not big on supplements, but the evidence looks strong that it
can do just that. In fact, I would throw CoQ10 into the same category as the
Super Sexual Herbs that I have written about,
i.e. a supplement that seems to help bedroom performance in a
lot of subtle but important ways.
Here is a list of 8 ways that CoQ10 can help you when it's showtime:
1. Blood Flow. In patients with a certain heart-related issues, left
ventricular dysfunction, CoQ10 improved blood flow.  This
has been verified in other patient subgroups as well, including statin-treated
diabetics . Most importantly, CoQ10 improved FMD (Flow Mediated Dilation)
in men with endothelial dysfunction.  A significant percentage of middle-aged
men in modern, industrialized societies have endothelial dysfunction and it is the root cause of
most erectile dysfunction. In other words,
CoQ10 will very likely help the men who need it most.
2. High Blood Pressure (Hypertension). One of the biggest risk factors for
sexual issues in males is high blood pressure. One meta-analysis, which is a study
of many studies, found that CoQ10 was significantly reduced high blood
pressure.  The abstract specifically states that "we conclude that coenzyme
Q10 has the potential in hypertensive patients to lower systolic blood pressure
by up to 17 mm Hg and diastolic blood pressure by up to 10 mm Hg without
significant side effects." These are impressive results that mean not only will CoQ10 likely give your
sex life an immediate erection-boosting increase in blood flow, but it will
protect your erections in the long term as well.
NOTE: Remember that most of the evidence for CoQ10 is not in young,
healthy patients, but rather with those with issues of aging and a modern
3. Nitric Oxide Protection. One way that CoQ10 does its magic is by
protecting your precious nitric oxide from oxidation.  This makes CoQ10
likely a synergistic supplement that will enhance other erectile supplements
(and medications), because it helps to preserve and protect nitric oxide through
a different metabolic pathway. 
4. Metabolic Syndrome. Another huge risk factor for erectile
dysfunction (and a lot of other nasty conditions) is Metabolic Syndrome.
In lab animals, CoQ10 improves many of the major risk factors for Metabolic
Syndrome.  Furthermore, the improvements were dose-dependent, i.e. the more
CoQ10, the less certain key signs of Metabolic Syndrome, specifically inflammation and free radical
damage. Even more remarkable was the fact that CoQ10 was able to prevent the
typical rise in insulin levels (from insulin resistance) that normally
accompanies this condition.

Nitric Oxide? Check out the
Peak Erectile Strength Diet where I show
you how to dramatically and naturally improve your erectile strength.
5. Testosterone Protection. Testosterone is the "Sex Hormone," and,
in my link on The
Causes of Andropause,
I discuss how mitochondrial damage is likely one of the root causes of the
age-related loss in testosterone that almost all men experience. CoQ10 is known for its mitochondria-protecting superpowers and, therefore,
may very well help protect your testosterone over the decades as well.
NOTE: CoQ10 can be expensive in health food stores, but is very reasonably
priced on Amazon:
Swanson Coq10 100 100 mg Softgels.
CoQ10 is poorly absorbed and must be taken with a little fat and ideally a
little Vitamin E as well. (Always talk to your doc first and see Caution below.)
6. Libido Protection. Dopamine could be termed the "Sex Neurotransmitter."
As I point out in my link on
Natural Dopamine Increasers, CoQ10
is also famed for
preserving brain dopamine and thus may help with sexual desire and
7. Fertility. Several studies have shown that
CoQ10 improves sperm factors and fertility. 
8. Wrinkle Reduction. Topical CoQ10 can also reduce wrinkles if done in
the right proportions. There are various Do It Yourself formulations out
there, including the Info Packs at Smart Skin Care. What does that have to do with sex?
We all know that half of performance is self-confidence and looking better can
help dramatically. See my link on
Wrinkle Reduction for Men for other
ideas as well.
CAUTION: The only caution that I know of with CoQ10 is that one study
showed that women with the highest levels of CoQ10 had an increased risk of
breast cancer.  This contradicts the work of other researchers, though, who
have used CoQ10 to treat cancer. See my link on Alternative Cancer Treatments
for more details.
CAUTION: If you have a medical condition or are on any medications, please discuss any changes with
your doctor first. Certain supplements, foods and even juices can alter absorption rates of certain medications for example. Play it safe.
