L-Arginine is a naturally occurring amino acid found in many foods. You
should know how L – arginine benefits to your health. It plays an important
role in the building of protein, which
helps the body repair and grow muscle. It also helps in the formation of nitric
oxide, which helps to open blood vessels. L-arginine also stimulates the body
to produce insulin and growth hormone, as well as other chemicals. It is often
used for circulatory purposes and is needed for the formation of proteins.
This
article reviews how L – arginine benefits to your health, its side-effects and applications
of L- arginine supplements.

How L – arginine benefits to your health |
What is L-arginine?
L-arginine is an amino acid that is essential or optional to proteins.
Unlike other amino acids, essential amino acids can’t be made by the body.
Instead, they need to be supplied through food.
It is classified as a semi-essential amino acid or a conditionally essential
amino acid, meaning it only becomes necessary under certain conditions and
circumstances (e.g., pregnancy, early infancy, severe illness, or trauma). It
is needed to synthesize nitric oxide (a signaling molecule) which is essential
for many body functions and processes (e.g. blood flow regulation, mitochondria
functioning, cellular communication, etc.). It also acts as a precursor for
other amino acids (glutamate, proline and creatine) which are needed for the
growth and maintenance of the immune system.

L-arginine is naturally present in foods high in protein |
What foods contain L-arginine?
L-arginine
is naturally present in foods high in protein, such as:
- Fish (salmon, haddock).
- Meat (turkey, chicken, and red meat).
- Legumes (such as chickpeas and soybeans).
- Whole grains (oats, brown rice).
- Nuts and seeds (pumpkin seeds, cashews).
- Dairy goods (cheese, yogurt, and milk).
It has
been estimated that 4-6 grams of L-arginine are consumed through food each day.
How L-arginine benefits to your health?
1. Nutrition Therapy:
L-arginine has been studied to help reduce the time it takes for wounds
to heal after surgery, and to help cancer patients build lean body mass when
used in combination with omega-3 fatty acids and nucleotides.
2. Blood pressure regulation:
L-arginine contains nitric oxide, which helps regulate blood pressure
and relax the blood vessels. Its supplements may help those with high blood
pressure to lower their systolic blood pressure (the highest number in the
blood) and their diastolic (lowest) blood pressure (the lowest number in the
blood).
3. Athletic performance enhancement:
L-arginine may increase exercise performance by increasing nitric oxide
levels in your body, which helps improve blood flow and a constant flow of
oxygen to your muscles, according to several studies. In one small study,
researchers found that athletes who took supplements had significantly higher
nitric oxide levels and were able to exercise for longer.
4. Blood sugar regulation:
L-arginine has not been extensively studied, but there is some evidence
that it may improve insulin sensitivity in people with diabetes and improve
glucose metabolism. Since nitric oxide must be made, L-arginine is needed.
Nitric oxide is an essential part of how cells function and how your body
responds to the hormone insulin. Insulin carries blood sugar from the blood
into your cells and uses it for energy. Boosting nitric oxide availability may
improve the performance of insulin-secreting cells and help your body better
use blood sugar.

5. Improving blood flow:
L-arginine has been shown to improve blood vessel health and improve
blood flow in certain groups of people. However, there is a lot of mixed
evidence, and many people think that it is useless. Peripheral Arterial Disease
(PAD) is a narrowing of the blood vessels that reduces the flow of blood to the
limbs. For patients with PAD, oral or intravenous L-arginine can increase blood
flow up to 8 weeks. However, it does not help increase walking distance or
speed for up to 6 months.
6. Erectile dysfunction:
L-arginine supplements have been studied in men with ED. It is thought
that L-arginine increases nitric oxide, which relaxes the muscles surrounding
the blood vessels supplying the penis. This causes the penis's blood vessels to
widen and blood flow to increase, which may help maintain an erection.
7. Management of
critical illness:
L-arginine is an amino acid that your body needs when your immune system
is weak due to infection or trauma. When your body’s physiological need for L-arginine
increases dramatically, your body can’t provide enough L-arginine. Therefore,
you need to supplement your body with L-arginine from external sources. When
your body needs too much L-arginine during or after surgery or illness, it can
lead to serious side effects, such as decreased blood flow and a weakened
immune system. Adding L-arginine to your diet may help reduce the negative consequences
of trauma or severe illness.
8. Treating pregnancy complications:
Pregnancy complications that may benefit from L-arginine include
preeclampsia (high blood pressure) and gestational hypertension (high blood pressure
during pregnancy). Pre-eclampsia occurs when the blood pressure and urine
protein levels are too high for the baby to survive. When given intravenously,
it can reduce blood pressure in pregnant women who are at risk for
preeclampsia. However, only medical professionals are allowed to administer
these IV products. It is not known if L-arginine can be ingested.
9. Other potential benefits:
- Easing inflammation of the digestive tract in premature infants - According to a study, L-arginine may aid in the prevention of
necrotizing enterocolitis (a serious condition that affects premature infants).
- Treating and preventing preeclampsia – Many studies have shown that treatment with L-arginine during pregnancy may help prevent and treat this condition.
- Correcting hereditary
disorders of urea synthesis - The urea
cycle in the body uses arginine to create urea, a substance found in urine.
- Treating peripheral
arterial disease - People who have
peripheral arterial disease may benefit from L-arginine because of its effects
on widening blood vessels.
- Chest pain (angina) - L-arginine supplementation appears to lessen angina symptoms, increase exercise tolerance, and enhance quality of life.
- High blood pressure
during pregnancy - Taking L-arginine
intravenously during pregnancy can lower blood pressure.
L-arginine may also help with a range of other health issues. However,
further research is needed to determine if it can help those with respiratory
illnesses breathe more easily, heal wounds faster, and reduce anxiety more
effectively. Therefore, it is important to consult with your doctor before
taking any dietary supplements.
What are possible side effects?
It is safe
and well-tolerated when used as a supplement for at least one year. However,
large doses can cause bloating, nausea and diarrhea, as well as stomach pain.
People with Asthma, Cirrhosis, Kidney Disease, Low Blood Pressure, and an
Inherited Deficiency (Guanidinoacetate Methyltransferase Deficiency) Affects
the Metabolism of this Amino Acid and may have adverse effects, although the
safety profile is supported by scientific evidence. Higher doses may worsen
heartburn or ulcers or digestive upset caused by medication because it
increases stomach acid. L-Arginine may worsen symptoms in patients with Herpes.
L-arginine
has been proven to be safe in many groups of people, including elderly people
and pregnant women. L-arginine are sometimes given to children in clinical
settings and are considered safe when prescribed in proper doses. However,
children should always be given arginine supplements under the supervision of
their doctor.
Dosage and Preparation:
There is no “right” dose for you. Factors such as age, gender
and medical history can influence the dosage that works best for you. Some
studies have looked at different doses to see how they affect different
conditions. For example, a 2–6 g dose given 3 times a day for up to 1 month was
found to help with chest pain. Another study found that a 5 g daily dose was
effective in treating erectile dysfunction, and a 4–24 g daily dose was used in
high blood pressure studies for up to 24 weeks. Talk to your health care
provider for specific guidance.
Conclusion:
L-arginine
is an amino acid that your body needs in order to function. You can get it from
your diet by eating some animal and plant-based protein. You can also get it as
a supplement by eating fish, red meats, poultry, soya, grains, beans, dairy
products, and more. Benefits of L-arginine supplements include: Improve heart
health, lower blood pressure, lower blood sugar, Improve athletic performance,
Oral and topically administered supplements are available. However, some
supplements may cause gastrointestinal problems and may interact with drugs.
Therefore, it is recommended that you consult a doctor before taking any
supplements. Consuming a healthy diet is the best way to get natural.
FAQ:
Q1. What are natural ways to get enough
L-arginine?
Answer: The best sources of natural L-arginine are foods rich in
protein. For some people, animal proteins such as red meat, chicken and turkey
breast meat, pork loin and dairy products are their main sources. If you are a
vegetarian or vegan, you may want to consider changing your diet to include
more protein-rich foods. Your doctor or dietitian may be able to recommend a
meal plan to help you increase your natural intake of L-arginine before taking
supplements.
Q2. What are interaction
with other medicines?
Answer: L-arginine may interact with medications used for erectile
dysfunction, high blood pressure, or diabetes, among other medications. Do not
take it if you are diabetic or have heart disease. As with many other
supplements, L-arginine has not been studied for safety in pregnant, nursing
women, young, old women, those with medical conditions, or those taking
medication.
Q3. What are the benefits
of taking L-arginine supplements?
Answer: L-arginine supplements are often used because
they can increase nitric oxide production, which can improve blood flow. This
improved blood flow can help people with conditions such as erectile
dysfunction by promoting better circulation. L-arginine is also thought to
promote cardiovascular health by relaxing blood vessels and lowering blood
pressure. Some athletes also take supplements because they believe they improve
exercise performance by increasing the supply of nutrients and oxygen to
muscles. However, it’s important to always talk to a healthcare professional
before adding any supplements to your routine.
Q4. Does L-arginine help
with erectile dysfunction?
Answer: As nitric oxide is a chemical that relaxes
blood vessels, it is thought to play a role in improving erectile function.
Nitric oxide can improve blood flow to your genitals, which is essential for
achieving and sustaining an erection. Some studies suggest that supplementing
with L-arginine may help people with mild-to-moderate erectile dysfunction
(MTFD). However, it’s important to remember that this effect can vary from
person to person, so it’s best to consult with your healthcare provider to
determine the best course of treatment for your ED.
Q5. How does L-arginine
improve exercise performance?
Answer: L-arginine helps improve exercise performance
by increasing nitric oxide production. Nitric oxide is a chemical that helps
dilate your blood vessels. When your blood vessels are dilated, your blood flow
increases. As your blood vessels dilate, your muscles get more oxygen and
nutrients. This can help increase your exercise tolerance and reduce fatigue.
While there are some studies that suggest that exercise performance can be
improved by taking certain supplements, individual reactions may vary.
Therefore, it is best to consult with a healthcare professional before adding L-arginine
to your fitness routine.
Q6. Can L-arginine
promote heart health?
Answer: L-arginine can help improve heart health by
increasing nitric oxide production, which relaxes and dilates blood vessels,
increasing blood flow. Improved blood circulation may help lower blood pressure
and improve overall cardiovascular function. While there are some studies that
suggest benefits, it’s important to talk to your doctor about the proper use
and potential risks for your individual heart health.
