Arginine supplements


What is the arginine:

Arginine is an amino acid polar basic. The name derives from the Latin argentum arginine, since it has been isolated for the first time precipitandone the silver salt. It was first isolated in 1886 from an extract of lupine seed of 1886 by the Swiss chemist Schultze.
 
In humans, arginine is considered essential amino acid in children, or should be taken in through the diet because the body is unable to synthesize sufficient amounts. Arginine in adults falls into the category of conditionally essential amino acids (along with glycine, glutamine, proline, and taurine) because plays a key role in maintaining homeostasis and body functions. In adults is synthesized in the urea cycle.

Essential amino acids are those amino acids that the body is unable to synthesize enough relative to its own needs and that therefore must be integrated by means of the diet. The fact that children do not synthesize a sufficient amount of arginine to requests organic could depend on the fact that in the phase accretion there is a substantial production of growth hormone whose synthesis appears to require, in addition to other substances, also the presence of arginine.

    


Arginine functions:
 

The functions of arginine are numerous and that their biological importance is due to its popularity. Sull'arginina have been a number of studies, which have shown some properties not all of the findings from these studies have found scientific evidence. To be fair, these are the likely properties of arginine.
 
SYNTHESIS OF AMINO ACIDS AND GLUCOSE

Arginine is a precursor of creatine and increases the rate of synthesis, properties that could positively affect athletic performance. Arginine is also active in the synthesis of other amino acids and that of glucose, acting in this respect as gluconeogenetico amino acid (arginine that can be catabolized to produce energy when the stored glucose is scarce).


DETOXIFICATION

Arginine is an intermediate product of the urea cycle and as such contributes to detoxify the body. During exercise is mainly due to the ammonia produced by the deamination of AMP (adenosine monophosphate) in muscle cells. The accumulation of ammonia is one of the factors leading to fatigue and detoxifying power of arginine may also be helpful in endurance sports (cycling, running, cross country skiing, etc..).
 


IMMUNOSTIMULATING

Arginine is also used as immunostimulante in the condition in which the body is weakened (burns, trauma, and various diseases)
 


IN ERECTILE DYSFUNCTION
 

The arginine intervenes in the synthesis of nitric oxide, a substance that induces vasodilatation by decreasing blood pressure and increasing the blood supply to the tissues, including genitals. This effect contributes theoretically increased desire and sexual performance. Arginine is therefore used for the treatment of erectile dysfunction.



 
 
COMPARISON OF ARGININE / VIAGRA
 

Such as sildenafil citrate (Viagra), L-arginine is thought to enhance the action of nitric oxide to the muscles surrounding the blood vessels of corpora cavernosa. As a result the blood vessels of the penis to dilate, increasing blood flow and consequently the erection same.
 
The difference between the two substances is that Viagra goes to block the PDE5 enzyme (which destroys nitric oxide), while arginine is used to increase the production of the oxide.
 
In one study, were administered to 50 men 5g of arginine per day, or a substance placebo. After six weeks, the men who have observed improvements were those who took L-arginine. Unlike Viagra, this substance must, in fact, be taken daily.
 
 
Among the alleged effects of arginine, its ability to increase sperm production and the recruitment of arginine is in fact suggested as a treatment in dispermie seminal.

According to some studies also intravenous infusion of arginine increased the serum concentration of GH hormone or growth hormone and prolactin.
 


IN CARDIOVASCULAR DISEASES

For these vasodilator properties, arginine may be useful in the treatment of cardiovascular diseases (hypertension, arteriosclerosis, angina and hypercholesterolemia).

  
Arginine in food
 

Normally a person takes 3.5 to 5 grams of arginine per day primarily through meat, nuts and plant foods rich in protein (legumes).
 
Doses interesting (the reference is relative to 100 g of product) of this amino acid are contained for example in the isolated soy protein (6.07 g), in the egg white powder (4.4 g), in the salted cod (3, 75 g), nuts, dried (3.62 g), peanuts (3 g), soy flour (2.67 g), cooked bacon (2.5 g) in dry almonds (2, 46 g), hazelnuts dried (2.22 g), in lentils (2.17 g), in turkey roast (1.98 g), in the shrimp cooked (1.83 g), chickpeas (1.82 g ), nell'aragosta cooked (1.8 g), in the anchovies (1.73 g), nell'aragosta (1.64 g), shrimps (1.63 g), in caviar (1.59 g), pork shoulder (1.57 g) and so on.
 
Arginine deficiency may be present in people who follow a strict vegetarian diet (vegan diet), under conditions of severe physical and psychological stress, disease or trauma.




Side Effects
 

The use of arginine is contraindicated to persons affected by frequent outbreaks of herpes virus, as this amino acid seems to favor episodes of reactivation of the virus strain. The amino acid lysine, on the other hand, appears to have the opposite effect, enhancing control herpes and genital sores that.
 
High doses of arginine (over 30 grams per day) may cause headache, hypotension and nephrotoxicity.

For doses below the most common side effects relate to episodes of diarrhea, abdominal cramps and nausea.
