What is arginine?


Arginine is a type of amino acid that is important for the normal functioning of blood vessels, but it is classified as a non-essential amino acid because it is produced in the body.

However, since the production capacity is not sufficient, the production amount decreases with age. It is said that in order to maintain good health, it is necessary to actively take the
deficient amount, but recently, arginine is included in supplements, nutritional drinks, nutritional foods, etc., so take it easy. I can.

Arginine was discovered in Germany in 1886 from the buds of legumes and is said to have shined golden. In German, it is “Argyros”.
Arginine came to be called arginine because it means arginine when it was translated into German.

Differences between L-arginine and arginine

When you check the ingredients of energy drinks, penis enlargement supplements, and energy drinks, you will often see the notations L-arginine and arginine.
There is no particular difference between L-arginine and arginine, as the difference between the two types is simply abbreviated and shortened.

I sometimes see the name D-arginine, but in fact, there are two types of arginine, L-type, and D-type.
L-type can be produced in the body, but D-type is said to rarely exist in the world, and even if it is ingested in the body, it will be excreted from the body without being absorbed.
For this reason, all supplements contain L-arginine or arginine.

The effect of arginine

When absorbed by the body, arginine promotes the production of nitric oxide, which is produced by the synthesis of arginine and oxygen.
Nitric oxide decreases with age and drops to about half in the 40s.
The following effects can be expected by always keeping the amount of nitric oxide.

Vasodilator action

Arginine has a vasodilatory effect and can improve male function comprehensively.
The effects obtained by this action are as follows.

Penis enlargement

By promoting blood circulation throughout the body, blood vessels in the male genitalia are also dilated.
As a lot of blood collects, the penis expands, and the size increases.

ED improvement

The mechanism of erection in men is that the production of nitric oxide dilates blood vessels, causing blood to collect near the male genitalia and making it easier to have an erection.
When the body is deficient in arginine, sufficient blood does not flow to the male genitalia, causing symptoms such as erectile dysfunction and creases.

Nitric oxide decreases due to low androgen levels, aging, diabetes, obesity, smoking, and stress.
Arginine has the effect of restoring the production of nitric oxide, so it can be said that taking it is also effective in improving ED.

In addition, the combined use of arginine with ED treatments such as Viagra, Levitra, and Cialis makes it easier to enhance the effects of ED treatments.

Promotes growth hormone secretion

Arginine has the effect of promoting the secretion of growth hormones.
By secreting growth hormone, it can be expected to have an effect on infertility, an improvement in immunity, and an anti-aging effect.

It is also effective for strengthening muscles and dieting.

Effect on the uterus

Arginine has the effect of promoting blood flow to the arteries connected to the uterus, so it can be expected to have the effect of thickening the endometrium.

Pregnancy promotion

From around the 40s, the quality of the egg deteriorates and it becomes difficult to get pregnant, but arginine can be expected to improve the quality of the egg, so it is also effective for improving infertility. ..

Increased sperm count

Arginine is the main ingredient in increasing sperm count.
By promoting the secretion of growth hormone, the number of sperms increases and it has the effect of activating activity, so it is also effective in improving male infertility.

Immunity improvement

Arginine has the effect of treating bacteria and foreign substances that have invaded the body and activating macrophages (a type of white blood cell).
By activating macrophages, resistance to bacteria and viruses will increase, immunity will increase, and you can expect to build a body that is less likely to get sick.
It is also effective in preventing injuries and post-surgery infections.


Arginine activates metabolism in the body and has the effect of maintaining normal skin turnover.
In addition, it promotes the regeneration of the skin against wounds, so repair is quickened, and it is possible to improve spots and acne from the inside of the body.

Treatment of hyperargininemia

Arginine has been shown to be effective in the treatment of hyperargininaemia.
Hyperarginineemia is a disease that occurs in 1 in 2.2 million people and is not caused by diet or lifestyle, but is congenital and is usually revealed by the age of 3 years.

The increase in arginine and ammonia in the blood causes abnormalities in the urea cycle.
Hyperargininemia causes growth retardation, ataxia, and intellectual impairment. The main symptoms are tachypnea, vomiting, impaired consciousness, and paralysis.

Insufficient arginine can cause the following symptoms:

・ Decreased male function (erectile dysfunction)

How to take arginine

Arginine can be produced in the body, but the shortage is supplemented by ingesting it.

The methods of taking arginine include diet, energetic agents, and supplements, but only about 20 to 50% of the amount taken is used. Therefore, it can be said that it is an ingredient that tends to be deficient.

Introducing the amount of intake and how to drink effectively.

Ingested from the diet

Basically, you can get arginine from your diet.
I will introduce what kind of ingredients contain a lot of arginines.
It is the amount of arginine per 100g of food.

In addition, brown rice, white rice, and bread, which Japanese people often eat, can only take arginine under 0.6g.
Also, if you try to take arginine from food alone, the calories will be exceeded, increasing the risk of obesity and diabetes, and if you take it daily, it will be a little difficult.

In addition to meals, take supplements so that your body does not feel overwhelmed.

Ingested from energy drinks and energy drinks

Energetic agents contain ingredients that enhance energy.

In the image, it seems that if you drink it, you may force an erection, but since it is a type similar to a supplement, it does not have the immediate effect of an ED treatment drug, and if you continue to take it, you will have erection power and energy. You can feel the effect of strengthening, nourishing tonic, and penis enlargement mildly.

As for energy drinks, the amount of arginine contained in one bottle is 1 to 2 g, so it is said that if you drink it to enhance sexual function, you will not feel much effect.

Penis enlargement supplement

Currently, there are many types of supplements. If you want to buy it, choose one that has a high effect on penis enlargement.

Ingredients that have an effect on penis enlargement are those that contain arginine, citrulline, and zinc. If this ingredient is listed, you can expect it.

As with energetic agents, you can’t expect immediate effects, but if you use supplements, you can easily continue to take them every day according to your purpose, and you can aim for an ideal size penis.
In addition, it also has the effects of promoting blood circulation and improving immunity, leading to the maintenance of health.


The daily intake required is not exactly stated, but it is estimated that 2-4g is effective for improving sexual function.
If you try from 3g a day and there are no side effects, you can increase it. For adults, it is safe to weigh up to 15-20g.

For athletes, it is said that it is effective to take about 10g because it uses muscles violently.
It is possible to take it from food, but if you take the shortage from supplements, you can keep the required amount.

An effective way to drink

Instead of taking arginine from foods and supplements all at once, take it in 3-4 divided doses.

Daily replenishment of arginine in the body helps maintain and improve health.

Timing is important for the efficient effect of arginine, so we will introduce it according to purpose.

Strength up

Take arginine about 1 hour before muscle training.
During training, nitric oxide levels increase to support muscle buildup.

In addition, growth hormone is more likely to be secreted during and after training.
By taking it before exercising, it is possible to reduce the feeling of fatigue.

Secretes growth hormone

Growth hormone is secreted most during sleep.
Taking arginine before bedtime can increase the amount of growth hormone secreted.

In addition, it is said that fasting is good to make it easier for arginine to be absorbed into the body.
If you are thinking of taking it after a meal, it is best to avoid it for about an hour after a meal and take it on an empty stomach before bedtime.

Side effects of arginine

If you take an appropriate amount, arginine is basically decomposed in the body and excreted from the body, so there is no concern about side effects.

Overdose may cause side effects in some people.
The reported side effects are that gastrointestinal disorders can cause abdominal pain, diarrhea, and vomiting.

When side effects are painful, it is possible to suppress the symptoms of side effects by taking citric acid together.
