Best Nitric Oxide Supplements

These days nitric oxide supplements have become popular with bodybuilders and athletes. Even fitness buffs are jumping on the supplement wagon. Some users report that these supplements can help build muscle mass, increase muscle strength, and give them the appearance of large muscles. But what is nitric oxide and how can nitric oxide supplements increase pump?

Nitric oxide is a naturally occurring gas in the body that is produced by the breakdown and conversion of the amino acid arginine. It has several functions in the body, including use in the circulatory and endocrine systems. Deficiencies of this gas can lead to fatigue and physical weakness.

Normally, when muscles are worked, such as in bodybuilding, nitric oxide gas appears naturally in response to the muscle contractions and blood vessel dilation. Blood is then able to fill the smooth muscles, making them appear larger. Unfortunately, this effect, referred to as "pump," doesn't remain. As soon as the muscles are no longer being worked, it begins to diminish and muscle take on a less full appearance.

Nitric oxide supplements are designed to aid in the release of nitric oxide throughout the day, instead of only when the muscle is being worked. This enables users to maintain the full, pumped appearance of muscles even after their workout is complete.

Nitric oxide relaxes and widens blood vessels, increasing circulation to organs and muscles that are in use. This creates a steady flow of oxygenated blood and nutrients to muscles that are being worked. The result is that muscles work more efficiently. They can also be worked longer without risking damage. The increased flow of blood and nutrients also speeds muscle repair.

Nitric oxide supplements also aid in hormone production, specifically adrenaline and gonadotropin releasing hormone (GnRH). Adrenaline, sometimes called epinephrine, is a hormone normally released by the body in response to stressors or perceived danger. When it is present, oxygen and glucose supply to the brain and muscles increases, making them work at peak performance.

Gonadotropin releasing hormone signals the production of follicle stimulating hormone (FSH) and luteinizing hormone (LH). These two hormones act in the testes to increase the production of the male androgen testosterone. In the body, testosterone has anabolic effects such as the growth, development and strengthening of muscle mass.

Those wanting to use nitric oxide supplements should keep a few things in mind. The first is that not all supplements are created equal. While many may promise outstanding results, several do not contain large enough amounts of L-arginine to produce the results desired. Two, it is possible to overdose on nitric oxide. Large amounts of nitric oxide can cause weakness or stomach discomforts such as diarrhea and nausea. There is no established tolerance level and some individuals may have lower tolerance levels than others. Most medical professionals recommend beginning by taking a small amount for a week, and then slowly increasing the dosage until you find your personal tolerance level.

Finally, there is some controversy surrounding the effectiveness of nitric oxide supplements. While there have been scientific studies on their use, the amounts given to test subjects were generally higher than what is traditionally found in consumer supplements. Also, in studies, the supplement is generally given through injections. Studies on the oral use need to be completed before it can be definitely said that this route of administration for the supplement is effective.

Consumers wishing to supplement their nitric oxide levels should consider carefully the reputation of the company that manufactures the nitric oxide supplements. While some may promise large results, if the supplement isn't given in adequate levels or has been mixed with other agents, you may not see the results you are looking for.

While nitric oxide supplements are commonly used by bodybuilders and athletes, they can also be used by fitness buffs or anyone wanting to improve muscle appearance and function. Whether you want to bulk up for competition or just feel a little more confident about the appearance of your muscles, these supplements may be able to help.
