L- arginine chemical structure

What are the health benefits and effects of  L- Arginine?

– boosts sexual performance ;
– supports healthy circulation ;
– contributes to the regulation ofblood pressure;
– prevents the aggregation/clogging of blood platelets;
– naturally increases the secretion of growth hormone ;
– improves immunity ;
– promotes soft tissue repair, plays a key role in the formation of collagen ;
– helps in ammonia neutralization, decreases ammonia  build-up;
– improves muscle metabolism.

What is L- arginine?

L- arginine ( also called arginine or ARG) is an “semi-essential” amino-acid. In other words, it can be synthesized by the body when needed. It is found in brown rice, oats, buckwheat, red meat, poultry, fish, dairy products, nuts and some wines. L- arginine is essential for the production of nitric oxide, a molecule that improves the heart and erectile functions. It is also responsible for the regulation and improvement of muscle metabolism, the functioning of the immune system and the construction of bones and soft tissues. L- arginine plays an important role in cell growth and multiplication, excretion of ammonia, wound healing, not to mention its importance in the release of growth hormone.

Why you should take L- arginine?

L- Arginine is a natural precursor of nitric oxide (NO)

Nitric oxide (NO , nitrogen monoxide ) is one of the simplest substances existing in nature. Naturally synthesized by the inner wall of the arteries, white blood cells and nerve cells, this gaseous molecule is very unstable and can not be ignored easily. Thus, to ensure many biochemical reactions in the body, a constant production of nitric oxide is required throughout life.

Nitric oxide causes relaxation of the vascular wall and therefore, an appropriate increase in the diameter of blood vessels. With this substance, the arteries dilate, allowing oxygen to reach all of our tissues. Nitric oxide reduces platelet aggregation, regulates blood pressure and thins the blood. Its benefits fully explain the effectiveness of nitroglycerin, classic drug releasing nitric oxide to prevent many cardiovascular diseases ( eg angina, myocardial infarction ) or relieve pain during a crisis.

Our immune cells (macrophages ) produce nitric oxide to eliminate pathogens and thereby stimulate wound healing. This little volatile mediator accelerates the passage of nervous signals in the brain regions involved in the regulation of emotions (aggressiveness, impulsivity, pain tolerance ). It is also assumed that nitric oxide is involved in the mechanisms of memory, learning and memory consolidation. The release of this molecule stimulates the secretion of mucus and allows the stomach and intestines to better adapt and ease the passage of the content of the bowel.

Essential to the initiation and maintenance of erection, nitric oxide causes relaxation of the muscles of the corpora cavernosa of the penis and a major expansion in the size of the penile arteries. Then follows a natural increase in blood flow to the penis, which leads to better erections.

Nitric oxide increases the diameter of the two cavernous arteries and improves certain characteristics ( International Index of Erectile Function ( IIEF ) and the Erectile activity index ( EAI) ) in patients with disorders of erection. The arginine molecule increases the strength and duration of hyperemia of the sex organs in both men and women . It prolongs the duration of intercourse and strengthens pleasant sensations and orgasm.

Arginine is an amino acid that enhances athletic performance.

Combined with other L- amino acids ( ornithine, glycine, L- lysine), arginine stimulates the secretion of growth hormone and insulin. This increases the build-up of muscle mass ( anabolic effect ), improves endurance, strength and fat burning. With its role as a precursor of nitric oxide, L- arginine allows many bodybuilders to gain muscle mass and have a hard sex drive, at an previously unknown degree. L- arginine is also involved in protein synthesis and thus in fast muscle recovery.

While supporting the immune system, L- arginine helps prevent the negative overtraining impact on the stability of the body ‘s natural defenses and resistance to infections.It allows rapid healing of wounds and injuries by accelerating the natural body’s healing processes. Through its metabolite ornithine ( another amino acid), L- arginine participates in the synthesis of bioactive molecules ( polyamines ), which are important for the growth and multiplication of all cells.

Finally, L- arginine in combination with glycine and ornithine, enters the urea cycle and increases the excretion of ammonia. Arginine also improves physical capacity and tolerance to stress, including endurance training, and thereby allows to boost athletic performance in athletes.

Deficiency of L- arginine results in poor wound healing, hair loss, skin rash, constipation, fatty liver and overproduction of ammonia.
Warning : toxic overdose may potentially lead to herpes and other viral and tumor diseases.

Contra Indications: not recommended to be taken if you have herpes, kidney failure, liver cirrhosis, asthma, heart attack suffered previously established coronary heart disease, glaucoma.Before taking any supplements, making any changes to your diet and if you have health issues, be sure to first consult with your doctor for advice.
