L-Arginine

L-arginine is one of many amino acids the body needs to function properly.  L-arginine plays a role in building protein. The body can use the protein to help build muscle and rebuild tissue.


Supporting research & information

While not exactly an “essential” amino acid — meaning an amino acid that the body cannot make on its own and, therefore, must get from outside sources — L-arginine is considered somewhat essential because it’s highly important for many functions yet usually present in low quantities, especially as someone gets older. One of the biggest benefits of taking arginine is its ability to improve blood flow and circulation. In the body, it is converted into nitric oxide, which causes blood vessels to open wider.

This has multiple benefits, including improving immune function, fertility, detoxification and brain power. Another important aspect of L-arginine is that it stimulates the production of certain hormones, especially beneficial growth hormones and insulin that help usher glucose into cells to be used for growth and energy output. This is one of the reasons it’s believed to enhance physical performance, stamina and strength.

Other L-arginine benefits include: 

  • fighting inflammation
  • lowering risk for arteriosclerosis and heart attack
  • repairing blood vessels
  • fighting congestive heart failure and coronary artery disease
  • helping lower high blood pressure
  • improving athletic performance
  • increasing immune function
  • reducing muscle pains (especially in the legs caused by blocked arteries)
  • improving kidney function
  • improving mental capacity
  • fighting dementia
  • correcting impotence, erectile dysfunction and male infertility

13 Proven L-Arginine Health Benefits 

Arginine is an amino acid that plays many different important roles in the body.  Among these include regulating blood pressure and circulation via nitric oxide, removing ammonia from the body, and healing of injuries.

Arginine is a conditionally essential amino acid that is used serves a variety of functions within the body. It is considered conditionally essential because healthy individuals can obtain enough of it from diet and from synthesizing it within the body via the kidneys.

Nearly all protein-containing foods have arginine in them, with the only exception being gelatin. Particularly rich sources of arginine include fish and walnuts, with as much of 15% of the amino acids being comprised of arginine in the latter xx https://www.ncbi.nlm.nih.gov/pubmed/17513442 Arginine can also be made from citrulline via the proximal tubule cells in the kidneys.

The majority of arginine in the body is used to process ammonia into the less toxic urea, as well to synthesize creatine and ornithine. A small portion is then used as a precursor to nitric oxide (NO), a compound that dilates blood vessels, lowers blood pressure, and helps maintain a healthy cardiovascular system [R]. Supplemental arginine is therefore used to increase the conversion of arginine into nitric oxide.

L-Arginine and L-Lysine Supplementations Help Reduce Anxiety
A controlled human trial experimented with L-Lysine and L-Arginine supplementation in healthy subjects with high anxiety levels. The subjects were given 3 grams of Lysine and 3 grams of Arginine daily. The results showed that the test group released more hormones in response to stressful situations. These hormones worked to decrease stress and anxiety in the subjects.

L-Arginine May Be Important In Maintaining Memory During Aging
Studies in rats have shown that maintaining Nitric Oxide levels seems to be important in memory function.It has been seen that aging caused levels of L-Arginine to be decreased in areas of the brain associated with memory (controlled study using rats). This could lead to decreased Nitric Oxide levels and decreased memory function. Supplementation could stop L-Arginine and Nitric Oxide levels from falling.
