Sex Drive Support - L-Arginine, Choline, Vitamin B5, DL-Phenylalanine
by Dusty R. Green, Research
Scientist / Author
In the 1990s, scientists
discovered that l-arginine, a non-essential amino acid commonly found in the
diet, is an oxidative precursor of nitric oxide (NO). L-Arginine works to increase
both the levels and activity of nitric oxide, leading to increased cGMP
increased blood flow to the genitals. Researchers at New York
University School of Medicine gave L-arginine to a group of impotent men, and
found that six out of 15 men receiving the amino acid claimed an improved
ability, while none of the 15 men in the placebo group
reported any benefits.
Sexual arousal occurs not just
in the genitals but in the whole body and, especially, in the brain. For men,
it actually begins when the brain sends impulses down the spinal cord and out
to the nerves that serve the penis. These impulses trigger the production of
nitric oxide (NO), which causes penile arteries to dilate and the spongy core
of the penis to relax and become engorged with blood. The neurotransmitter
that carries the sexual message is
(ACh) which is important for women, too.
Numerous studies confirm a key
role for cholinergic nerve transmission in sexual responses.
Simply speaking, with too
sex drive / sexual
health can decline. Increase ACh levels, and
sexual activity goes up. ACh is involved in the build-up toward orgasm and the
urethral and vaginal contractions that occur during orgasm as well as the
subjective perception of orgasm intensity and duration.
In addition to its direct role
in sex drive support, ACh is also the primary chemical the body uses to
transmit signals from nerves to skeletal muscles, the muscles that move the
body. You need this chemical for muscular control and proper muscle tone.
There is reason to believe that enhancing cholinergic neuromuscular
transmission will enhance your energy and stamina by raising your ACh levels
and that this can provide indirect sexual benefits.
While drugs can enhance the
body's cholinergic activity, these drugs not only have unpleasant or even
dangerous side effects but are available only by prescription. One way to
safely and effectively enhance ACh levels is to take supplements of
/ vitamin B5. Or, the full menu of Life Extension Mix (a
multi-vitamin/mineral formula) contains generous amounts of vitamin B5
Another form of choline can be found in
under the name Glycerylphosphorylcholine (GPC)
and another in
Extension IQ. We also sell
choline as a
Vitamin B5, also known as
pantothenic acid or calcium pantothenate, appears to enhance endurance:
- When a person is in a state of deficiency ... as most are who depend on food for B5 and,
- Since an ample amount is needed for creating ACh from
choline, it is paramount in its role in the energy-producing Krebs Cycle which is vital for all living cells.
An early indication that vitamin B5 might
enhance physical endurance came from a study in which rats were placed into a
tank filled with cool (64F) water and forced to swim until they became
Prior to their
swim, the rats diets had included either high, adequate, or
deficient levels of vitamin B-5. The high dose rats lasted
more than four times as long as those whose diet had been B-5
deficient. In another experiment, pieces of frog muscle
were stimulated electrically to make them twitch. The
stimulation continued until the muscle became exhausted.
Muscle tissue that was bathed in vitamin B-5 had double the work
output as the control muscle. [Ralli, 1953].
Others to Consider for Sex
Dosage and Timing
Experienced users recommend
taking choline plus vitamin B5 (or B-5 by itself) about 20 to 30 minutes before
sex in order to get the full effect right from the start. But, notes one user,
"Don't worry if you start too soon, it'll kick in as you're going."
He adds, "Not everybody will notice it, but if you set a clock, you'll notice that you have the energy to go longer. Pretty much everyone
I've told about B-5 has experienced that effect."
Combinations that many people
have found effective include three times as much choline as B-5 (for example,
500-1,000 mg of B-5 in combination with 1,500-3,000 mg of choline). It is
probably wise to begin with lower doses in this same ratio, and gradually
increase the dose as tolerated.
Several lines of evidence link
activity of the neurotransmitter dopamine in the brain with sexual behavior.
Generally, it appears that higher levels of dopamine are associated with more
sexual interest and vice versa. Increased brain dopamine activity caused by
taking the drug L-dopa is believed to be the cause of a hypersexuality
syndrome in people who take the drug for Parkinsons disease.
L-dopa is a chemical precursor
of dopamine (which in turn, is a precursor of norepinephrine). In other words,
the body uses L-dopa to make dopamine. L-dopa is available only by prescription but you can also increase your brain dopamine levels by taking
the non-prescription amino acids that the body uses to make L-dopa -- tyrosine
and/or phenylalanine. L-Theanine, an extract from green tea
also is a dopamine enhancer to consider.
People who have lost interest
in sex because they are depressed may benefit from taking doses of 100 to 500
milligrams of DL-phenylalanine. Supplements of
C, folic acid and
copper, may help maximize the conversion of L-dopa to dopamine.
