L-Arginine
What is L-Arginine?
L-arginine is an amino acid that has numerous functions in the body. It
helps the body get rid of ammonia (a waste product), is used to make
compounds in the body such creatine, L-glutamate, and L-proline, and can
be converted to glucose and glycogen if needed.
L-arginine is used to make the nitric oxide, a compound in the body that
relaxes blood vessels. Preliminary studies have found that L-arginine may
help with conditions that improve when blood vessels are relaxed (called
vasodilation), such as atherosclerosis, erectile dysfunction, and intermittent
claudication.
L-arginine is also involved in protein formation. In larger amounts, L-arginine
stimulates the release of hormones growth hormone and prolactin.
Why Do People Use L-Arginine?
Heart disease
In the body, L-arginine is used to make nitric oxide, which reduces blood
vessel stiffness, increases blood flow, and improves blood vessel function.
However, L-arginine should not be used following a heart attack.

An study sponsored by the National Institutes of Health examining the use of
L-arginine after a heart attack was terminated early after six patients died, a
disproportionate number. There were no deaths in the patients who did not
receive L-arginine.
The study researchers speculate that L-arginine may aggravate the effects of
cardiac shock. The results were published in the Journal of the American
Medical Association.
Erectile Dysfunction
L-arginine has been used for erectile dysfunction. Like the drug sildenafil
citrate (Viagra), L-arginine is thought to enhance the action of nitric oxide,
which relaxes muscles surrounding blood vessels supplying the penis. As a
result, blood vessels in the penis dilate, increasing blood flow, which helps
maintain an erection. The difference in how they work is that Viagra blocks
an enzyme called PDE5 which destroys nitric oxide and L-arginine is used to
make nitric oxide.
In one study, 50 men with erectile dysfunction took either 5 grams of
L-arginine per day or a placebo. After six weeks, more men in the L-arginine
group had an improvement compared to those taking the placebo.
Unlike Viagra, L-arginine must be taken daily.
Wound healing
L-arginine's possible activity in wound repair may be due to its role in the
formation of L-proline, an important amino acid that is essential for the
synthesis of collagen.
Other Conditions
L-arginine is also used for high blood pressure, migraines, sexual
dysfunction in women, intermittent claudication, and interstitial cystitis.
Sources of L-Arginine
L-arginine is conditionally essential, which means that the body normally
has enough. It's produced in the kidney and to a lesser extent, in the liver.
Food sources of L-arginine include plant and animal proteins, such as dairy
products, meat, poultry, fish, and nuts. The ratio of L-arginine to lysine is
also important - soy and other plant proteins have more L-arginine than
animal sources of protein.
Severe burns, infections, and injuries can deplete the body's supply of
arginine. Under these conditions, L-arginine becomes essential and it is
necessary to ensure proper intake to meet the increased demands.
L-arginine is also essential for children with rare genetic disorders that
impair the formation of L-arginine.
Side Effects of L-Arginine
L-arginine may lower blood pressure because it is involved in the formation
of nitric oxide. It may also result in indigestion, nausea, and headache.
L-arginine should not be used following a heart attack. If you have a history
of heart disease, consult your doctor before taking L-arginine.
Higher doses of arginine can increase stomach acid, so it may worsen
heartburn, ulcers, or digestive upset cause by medications. Arginine
appears to increase stomach acid by stimulating the production of gastrin, a
hormone that increases stomach acid.
L-arginine may also alter potassium levels, especially in people with liver
disease. People with kidney disease and those who take ACE inhibitors or
potassium sparing diuretics should not use supplemental L-arginine
unless they are under professional supervision. It may also alter the levels
of other chemicals and electrolytes in the body, such as chloride, sodium,
and phosphate.
Arginine may increase blood sugar levels, so it shouldn't be used by people
with diabetes unless under a doctor's supervision.
Pregnant and nursing women and children should not use supplemental
L-arginine, as it's safety has not been established.
People with genital herpes should not take L-arginine because it may
aggravate their symptoms.
Possible Drug Interactions
L-arginine may counteract the benefits of lysine to treat herpes
NSAIDS (non-steroidal anti-inflammatories) or other drugs that are hard on
the stomach should not be combined with L-arginine.
Drugs that alter potassium levels in the body, such as ACE inhibitors and
potassium sparing diuretics.
