Pine bark extract boost for blood flow and heart health - Nutra USA,
10/18/07 - "Acetylcholine stimulates the cells of
arteries to produce NO from L-arginine faster ... In turn, the NO causes the
muscle surrounding arteries to relax, which results in an increase of blood
vessel diameters. When subjects had taken Pycnogenol the relaxation of
arteries was increased by 42 per cent as compared to the group taking
placebo tablets" - See

Statins' Effect on Endothelial Function Enhanced by L-arginine in Some
Patients - Doctor's Guide, 6/11/07 -
"endothelium-dependent dilation (EDD)
... simvastatin had no appreciable effect on EDD (6.2±1.2% vs. 6.1±0.9%) in
subjects with elevated ADMA. However, the addition of L-arginine to
simvastatin significantly improved EDD (9.8±1.5% vs. 5.3±0.8%; P <.01).
There were also significant improvements in EDD in response to L-arginine
alone"

- Nitric Oxide Now -- Ask Me How -
WashingtonPost.com, 10/6/03 - "In
the arteries, the innermost layer of cells releases
nitric oxide to signal smooth muscle cells to dilate (increase the
diameter of) the arteries. This allows blood to flow more freely,
particularly during exercise ... By the 1990s, many scientists saw nitric
oxide as the next great weapon for treating heart disease, impotence and
even bacterial infections ... Niteworks has L-arginine and also
L-citrulline, which recycles spent L-arginine by resupplying it with
atoms it lost producing nitric oxide ... "Ninety dollars a month? That's
obscene," Murad said. "You can probably get [vitamin] C and E for pennies a
day. You can probably get arginine for about a dollar a day"" - See

might work together with L-arginine to prevent
inflammation in the branch areas of blood vessels ... although
antioxidants may not reverse or repair pre-existing damage within blood
vessels, they may slow the long-term progression of atherosclerosis"

Remedy for Erectile Dysfunction - New Hope Natural
Media, 9/5/02 - "received three
separate treatments for two weeks each, in random order: (1) 3.25 grams of
arginine plus 6 mg of
yohimbine, (2) yohimbine
alone and (3) placebo ... Combination treatment was considered successful by
40% of the participants, compared with 28.9% with yohimbine alone and 17.8%
with placebo ... Arginine is available in health food stores without a
prescription, but yohimbine can be obtained only with a doctor's
prescription. Although the herb yohimbe is sold in health food stores, it
contains much less yohimbine than the amount used in the new study" -

- Yohimbine Plus L-Arginine Potential Therapy For Mild To Moderate Erectile
Dysfunction - Doctor's Guide, 7/31/02 -
"randomly assigned 45 men with
erectile dysfunction to treatment with 6 mg of
L-arginine glutamate combined with 6 mg of
yohimbine hydrochloride, to 6 mg of
yohimbine hydrochloride
alone, or to placebo ... They took the drugs orally one to two hours before
intended sexual intercourse ... Changes in this score [Index of Erectile
Function (IIEF)]
were significantly greater among patients taking yohimbine
plus L-arginine compared to those taking placebo" - Note: That "6 mg
of L-arginine glutamate" has to be a misprint. It probably should have
been 6 grams as in a
U. of Texas study on
postmenopausal women.

-
Arginine for Muscles, Memory, Sex and More - Life Enhancement Magazine,
12/99 - "Arginine is the primary
source of the nitrogen that results in production of the important biomolecule
nitric oxide (NO) ... NO helps defend the
body against invading bacteria2 and parasites. In the brain, where it is
formed in nerve cells, it diffuses in all directions, activating all cells
in the vicinity, thus modulating many functions, including behavior and
gastrointestinal transit flow. The release of NO is absolutely essential for
motor learning in the cerebellum (coordination), and it also appears to be
necessary for long-term potentiation in the brain, which is the mechanism
involved in long-term memory. NO is now also thought to be important in our
olfactory (smelling) sensations and our capacity to identify different
scents ... Free arginine has been shown to help prevent a destructive
process known as
cross-linking, which is associated with accelerated aging. Excessive
cross-linking reactions inevitably damage the kidneys, necessitating
dialysis in advanced age"

Study finds new therapy for impotence - CNN, 10/27/99 -
"Nitric oxide is the messenger, if you will, the signaling molecule, and
without that signal you can't get that signal from the brain to the penis
for the erectile process ... An amino acid call L-argenine produces nitric
oxide in the body"

Viagra anniversary sees herbal competitors by the dozens - CNN, 3/26/99
- "Since the main problem in
impotence is actually a problem with circulation of the blood vessels in the
penis, l-arginine holds great promise for men with physical impotence"
- Prosexual
Enhancement - Life Enhancement Magazine, 3/97 -
"According to numerous anecdotal reports from highly satisfied arginine
users since the early 1980s, dietary L-arginine can give men erections that
are bigger, harder, more frequent, and longer lasting. Some men also report
that L-arginine gives them greater endurance. In women, L-arginine has been
reported to increase the intensity of sensation during sex. One highly
athletic 30-something woman tells about the time she told her doctor about
her L-arginine use. "My doctor almost fell off his chair when I told him how
many times a night I do it - six-times," she said. "He's definitely taking
arginine now, too.""

"The NAC+ARG administration seems to be a potential well-tolerated
antiatherogenic therapy since it improves the endothelial function in
hypertensive patients with type 2 diabetes by improving NO bioavailability
via reduction of the oxidative stress and increase of NO production. Our
study's results give prominence to its potential use in the primary and
secondary cardiovascular prevention in these patients"

Biomarkers of arginine and lysine excess - J Nutr. 2007
Jun;137(6):1662S-8S - "Arginine
supplementation is used in several disease states. In arginine-deficient
states, supplementation is a logical choice of therapy. However, the
definition of an arginine-deficient state is complex. For example, plasma
arginine levels could be within normal range but intracellular arginine
levels could be reduced because of membrane transport problems. Lysine
competes with arginine for transport into the cell. In these situations,
arginine supplementation of higher than required levels is proposed.
Arginine has several important functions in metabolism as it is a precursor
of metabolically active components such as nitric oxide (NO), ornithine,
creatine, and polyamines"
