To Your Heart Health

Your cardiovascular system
is the driving force behind
Cellular Nutrition. Over 100,000 miles in
length and equipped with nearly six-trillion
endothelial cells, your blood vessels produce
the Nitric Oxide that supports Cellular
Nutrition. Endothelial-derived Nitric Oxide
functions in many important ways to
support the cardiovascular and circulatory
system. Endothelial damage, from a poor
diet, obesity and lack of exercise, results
in deficient Nitric Oxide production
and, therefore, increased risk of
cardiovascular disease. Fortunately,
there are easy ways to make
your endothelium healthy by adjusting your diet,
engaging in moderate exercise and taking
How does Nitric Oxide work?
Nitric Oxide, also known as NO, is the body’s most
widespread signaling molecule. NO promotes Cellular
Nutrition by facilitating blood flow to every cell in the body.
Because NO expands the diameter of the arteries, more
nutrients are delivered to the cells and more waste products
are removed from the cells. Nitric Oxide provides Cellular
Nutrition to all organs of the body and also protects these
organs against injury and disease caused by exposure to
oxidants, a condition known as “oxidative stress.” NO is the
body’s most potent antioxidant, protecting cells against freeradical
damage. In this regard, NO functions just like vitamins
E and C.
NO deficiency and endothelial dysfunction
Cardiovascular disease is the leading cause of
morbidity and untimely death in the U.S. and is
sometimes associated with NO deficiency. The
diseases resulting from NO deficiency include
hypertension, stroke, atherosclerosis, heart attacks,
diabetes, Alzheimer’s disease, gastrointestinal ulcers
and erectile dysfunction. A healthy vascular
endothelium is essential to a healthy cardiovascular
system because it is required for normal NO
production and action. Vascular-endothelial
dysfunction leads to decreased NO production and
increased oxidative stress, creating a vicious cycle
that promotes further endothelial dysfunction.
Promoting a healthy endothelium
The most important mechanism by which the
body stimulates endothelial NO production is
exercise. Physical activity promotes blood flow
through the millions of arteries in the body
and the friction of the blood flowing against
the endothelial cells lining the arteries
stimulates the production of NO. This is
how exercise promotes not only a healthy
heart and healthy cardiovascular
system, but also a healthy body,
and it’s all due to the work
of NO to promote Cellular
Supplements increase NO production
In addition to exercise, taking
certain nutritional supplements can increase the
production and action of endothelium-derived NO.
These natural substances include L-arginine and Lcitrulline,
which serve as the body’s fuel to make NO,
and L-taurine, vitamin C, vitamin E and alpha-lipoic
acid, which work to protect NO against oxidative
destruction by free radicals.
contains L-arginine, L-citrulline, vitamin C,
vitamin E and other beneficial ingredients. When taken
together at the same time, the natural ingredients in
Niteworks may enable endothelial cells to produce
more NO for a healthy endothelium, lower blood
pressure and protection against cardiovascular disease.
Diet improves heart health
Another way to keep your endothelium healthy is
through diet. A sensible diet that is low in fats and
carbohydrates, but rich in proteins, will go a long way in
promoting cardiovascular health. Decreased fat intake
greatly reduces the body’s production of destructive
free radicals and decreased dietary carbohydrates limit
the intake of calories. Eating a high protein diet
maintains muscle mass and energy levels. The
combination of high protein plus low carbohydrates and
fats can result in substantial weight loss, which further
promotes a healthy cardiovascular system.
A winning combination
The three lifestyle changes outlined–mild to moderate
exercise, a high-protein diet and Niteworks - have
something in common: they all play a role in enhancing
the production and action of endothelium - derived Nitric
Oxide. For this reason, exercise, diet and Niteworks
are a winning combination for maintaining and
improving your endothelial health - and a healthy
endothelium means a healthy heart. When you combine
their results, you can easily see how your overall health
and general well-being can improve.
|News About Blood Pressure
Normal blood pressure values revised
lower by American Heart Association
The American Heart Association recently lowered
the values for what it considers to be a “normal”
blood pressure. In an article published in the
Journal of the American Medical Association in
May 2003, the Seventh Report of the Joint
National Committee on Prevention, Detection,
Evaluation, and Treatment of High Blood Pressure
provided new guidelines for hypertension
prevention and management.
The report indicated that a systolic blood pressure
of 140 mm Hg or greater is a very important risk
factor for cardiovascular disease. Systolic/
diastolic blood pressure readings of 115/75 are
now considered to be normal, rather than the
previous figures of 120/80. This means that blood
pressure readings of over 115/75 are clear-cut risk
factors for cardiovascular disease. Moreover, the
risk for cardiovascular disease doubles with each
increment of 20/10 mm Hg.
Individuals who have a normal blood pressure at
55 years of age have a 90% lifetime risk for
developing hypertension. Individuals with a
systolic blood pressure of 120 to 139 mm Hg or a
diastolic blood pressure of 80 to 89 mm Hg
should be considered prehypertensive and require
health and lifestyle modifications to prevent
cardiovascular disease. Antihypertensive drug
medication might be necessary as an adjunct to
improved lifestyle to control high blood pressure.

Who Says When You Snooze You Lose?
Used to be, we thought getting 8 hours of sleep a night was the most we could do to restore ourselves.
Then came Niteworks.
Herbalife’s innovative one-of-a-kind formula to promote cardiovascular health
was developed with Nobel Laureate in Medicine Dr. Lou Ignarro. And now
is also available in a convenient 15-day supply, perfect for trying
out the product or packing for travel.
The benefits of Niteworks include:
Enjoy Niteworks any
time of day. Or drink a glass at bedtime and make every wink count.
- A boost in nitric oxide, to help arteries stay flexible and youthful.
- Enhanced blood flow for better functioning of the heart, brain and other organs.
- Increased energy and rejuvenation.*
