Nitric oxide supplements are a popular choice for bodybuilders and elite athletes looking to develop endurance or lean, hard muscle mass. But what is the best nitric oxide supplement? What does nitric oxide actually do? And is supplementation for you?

Nitric oxide (NO2) is a naturally occurring gas. You might have heard of its use in speed racing and at the dentist’s office, but it’s also found throughout nature, and is produced as part of your normal bodily processes. Acting as a way to pass signals between cells, NO2 helps your tissues function at optimal levels, assisting your memory, boosting your immune system, reducing inflammation, helping digestion and increasing your overall strength, endurance and physical performance.

Nitric oxide is often prescribed for its amazing cardiovascular benefits. The substance is found in your arteries, and is often prescribed to patients needing to improve their heart function. Nitric oxide based medicines may be given to patients suffering heart disease or stroke, to help get more oxygen flowing through narrowed blood vessels and impaired bodily tissues.

As you exercise, the level of NO2 in your body increases. This plays a vital role in helping your muscles obtain the oxygen they crave, and the best nitric oxide supplements super-charge this natural function. Supplementing with NO2 boosts blood flow throughout your body and improves the way oxygen and essential nutrients are delivered as you pump iron, run that extra mile, or play your favorite team sports.

Nitric oxide helps the creation of the vital proteins essential for muscle growth, as you build strength, endurance and lean mass. Supplements are also thought to improve your fatigue levels, allowing you to maximize your workout potential. Once you’re done working out, NO2 goes one better and gets your recovery rolling along by encouraging muscle relax and rebuild. This means even as you wind down after exercising, your performance is enhanced, and you’ll be getting the most out of the effort you put in.

These are found in foods such as nuts, meats and dairy in small quantities, but to get even more outstanding results, top athletes and bodybuilders are choosing to increase their NO2 using some of the best nitric oxide supplement options.

There are a wide range of supplements available on the market. If you’re looking to increase your performance, want to train harder, or want to get an extra boost our of your exercise regimen, supplements containing L-citrulline or L-arginine may help enhance your overall workout efficiency. If you’re the sort of person who wants to go hard, get hard and get results, NO2 supplementation is a worthwhile addition to your diet.

If you do choose supplementation, make sure you read any packaging carefully to ensure the NO2 supplement you choose meets your health and workout requirements. Never exceed the recommended dose. Supplements can be taken in powder, liquid, pill, tablet or capsule form, and dosage varies.
