Helps Regulate Healthy Immune System*

  • Indispensable for optimum growth.
  • Stimulates the release of growth hormone
  • Important to muscle metabolism; acts as a vehicle for transport, storage and excretion of nitrogen.
  • Increases muscle mass while decreasing the amount of body fat.
  • Plays an important role in post-injury problems such as weight changes, nitrogen balance and tissue healing.
  • Increases collagen, the main supportive fibrous protein found in bone, cartilage and other connective tissue.
  • Stimulates the immune system.
  • Combats physical and mental fatigue.
  • Increases spermatogenesis.
  • Used in the treatment of hepatic [liver] disorders.
  • Transforms to L-Ornithine and urea.
  • Promotes the detoxification of ammonia which is poisonous to living cells.
  • Supports Protein Synthesis
  • Promotes healthy circulation!
  • Stimulates release of human
  • growth hormone (HGH)

What does it do? 

The amino acid arginine has several roles in the body, such as assisting in wound healing, helping remove excess ammonia from the body, stimulating immune function, and promoting secretion of several hormones including glucagon, insulin, and growth hormone.

The effect on growth hormone levels1 has interested body builders. In a controlled trial, when combined with weight training and ornithine (taken as 500 mg of each, twice per day, five times per week), a greater decrease in body fat was obtained after only five weeks than when the same exercise was combined with placebo.2

Arginine is also needed to increase protein synthesis, which can in turn increase cellular replication. Therefore, arginine may help people with inadequate numbers of certain cells. For example, some,3 though not all,4 studies have found that men with low sperm counts experienced an increase in the number of sperm when supplemented with arginine.

Arginine’s effect on increasing protein synthesis improves wound healing. This effect has been shown in both animals5 and, at 17 grams per day, in people as well.6

Arginine is also a precursor to nitric oxide, which the body uses to keep blood vessels dilated, allowing the heart to receive adequate oxygen. Preliminary evidence suggests that arginine may help regulate cholesterol levels.7 Arginine also appears to act as a natural blood thinner by reducing platelet aggregation.8

According to researchers, the effect arginine has on increasing nitric oxide might help people with interstitial cystitis. In a preliminary trial using 1.5 grams of arginine per day, symptoms of this condition were significantly reduced.9

L-ARGININE 500
Supports Protein Synthesis. L-Arginine is a semi-essential amino acid synthesized by the body from ornithine. Arginine supports protein synthesis as it is involved in the transport and storage of nitrogen. Arginine is important for proper physical performance because it is used by the body to produce creatine.*
Promotes healthy circulation!
L-arginine is an amino acid that plays an important part in the body's production of nitric oxide. Nitric oxide promotes vasodilation (relaxation of blood vessels), helping to maintain healthy blood flow throughout the body. Because of this effect, l-arginine is considered useful for concerns that improve with enhanced circulation, including men's sexual health.*

Arginine is considered a semi-essential Amino Acid as it does not fall perfectly in the essential or nonessential categories. According to Jon Pangborn in Yearbook of Nutritional Medicine, during growth periods (i.e. Body Building and wound healing) insufficient 

Arginine can be synthesized in the body at adequate levels for maintenance in adults

Arginine has been widely used by Olympic and professional athletes for safe buildup of muscle mass. Dr. Pangborn goes on further to state that 

Arginine is a critical component in stimulating the pancreas to release insulin. Therefore, Arginine may be indicated in some diabetics. 

Arginine has been shown to stimulate Thymus function and may therefore be indicated in Immuo depressed individuals. . It may not, however, be produced quickly enough during periods of growth, and is considered essential at those times.

Arginine stimulates certain glands, particularly the thymus and the pituitary. Because the pituitary secretes growth hormone, arginine is required for normal growth. And because of this participation in growth, it has become very popular for its muscle-building and fat-burning effects among athletes. 

Other functions of this amino acid are its ability to aid in liver detoxification, maintain immune function, boost sperm count, and assist in conditions involving kidney impairment. It also causes retardation of tumors and cancer. 

Arginine is thought to be beneficial in the treatment of cirrhosis of the liver and other liver problems. Its high content in scar tissue points to its involvement in tissue repair and collagen production. 

Arginine also contributes to increases in muscle mass and decreases in body fat. 

Pregnant and lactating women should avoid taking arginine because of its involvement in growth and shedding of fat. Since arginine is required for the herpes virus to replicate, reducing arginine in the diet appears to lessen the normal growth of herpes.

- Q & A -
 
 

Where is it found? 

Dairy, meat, poultry, and fish are good sources of arginine. Nuts and chocolate also contain significant amounts of this amino acid.

Who is likely to be deficient?

 Normally, the body makes enough arginine, even when it is lacking in the diet. However, during times of unusual stress (including infection, burns, and injury), the body may not be able to keep up with increased requirements.

How much is usually taken? 

Most people do not need to take extra arginine. While some people with serious infections, burns, or other trauma should take arginine, appropriate doses must be determined by a doctor. Levels used in research vary considerably (2–30 grams per day). Optimal intakes remain unknown and are likely to vary depending upon the individual.

Are there any side effects or interactions?

 Arginine has so far appeared to be free of obvious side effects, although some doctors are concerned that increases in growth hormone triggered by arginine could overwork the pancreas.

Individuals with kidney or liver disease should consult their nutritionally oriented doctor before supplementing with arginine. Individuals with herpes (either cold sores or genital herpes) should not take arginine supplements, because arginine can stimulate replication of the virus.

Large amounts of arginine in animals can both promote10 and interfere with cancer growth.11 In preliminary research, high intake (30 grams per day) of arginine has increased cancer cell growth in humans.12 On the other hand, in people with cancer, arginine has been found to stimulate the immune system.13 At this time it remains unclear whether arginine is dangerous or helpful for people with cancer.

Arginine works with in the synthesis of growth hormone

At the time of writing, there were no well-known drug interactions with arginine.
