L-Arginine: Important For Athletes and Non-Athletes Alike

While you might remember hearing about the amino acid L-Arginine back in school, you are probably not aware of everything it can do. This supplement is incredibly helpful for athletes of all stripes, especially those engaged in serious weight training.

However, other people interested in increasing their energy levels, improving their overall immune function, lowering blood pressure and a whole host of other great benefits will also be well served through supplementation with L-Arginine.

What is L-Arginine?

L-Arginine is a semi-essential amino acid. This means that while the body can produce some on its own, a significant portion of the required levels must come through either food or supplementation. All amino acids are the building blocks of protein; vital substances involved in the protein synthesis process.

This amino acid is found in many protein rich foods. For example:

  • Beef
  • Pork
  • Poultry
  • Dairy Products
  • Seafood
  • Gelatin
  • Wild Game
  • Wheat Germ
  • Flour
  • Granola

L-Arginine also is helpful in a number of additional bodily functions. Normally, it requires using lots of ATP (Adenosine Tri Phosphate) in order to produce this substance. ATP can be thought of as energy. It also is a vital component involved in the production of nitric oxide and the removal of waste products from the body, especially ammonia.

Benefits of L-Arginine

Supplementation with L-Arginine has been shown to increase energy. This is observed through the fact that the use of ATP is not needed when it is taken in through a supplement. In addition, a number of other processes are enhanced. This includes an increase in the speed of cell division, the healing of wounds and the release of certain hormones.

This supplement is also helpful in repair and relief of cells. This means faster recovery times, reduced pain in muscles and tissues. Other studies also support the fact that as nitric oxide is produced, blood vessels relax, which allows for the removal of toxins and waste products, particularly ammonia.

This is also helpful in the production of Human Growth Hormone, which may lead to increased muscular gains in weight training athletes. The release of insulin is also thought to be stimulated, which may contribute to further muscular gains, while limiting or inhibiting the storage of fat.

Many users also report a lowering of their blood pressure, possibly due to the relaxed blood vessels and overall improved circulation. Some users have also reported an easing in the severity and frequency of their headaches and migraines.

All of these benefits are hard to ignore. This is true whether you are an athlete, student or busy mother or father. The potential that L-Arginine supplementation may have to improve your lives should be reason enough to give it a try today.
