Fact Checked

The best nitric oxide supplements on the market can help you take your workouts to the next level. They work by increasing muscle pumps, vascularity and performance when working out.

Remember when Arnold said:

“The most satisfying feeling in the gym is the pump, is at as satisfying  to me as cummin is”

If you’re a serious lifter you definitely know this feeling, when your muscles get bigger as blood rushes into them while lifting weights.

You know that when your biceps feel so tight like they could explode you just gave it your all and the bodybuilding gods will grant you sick gains as long as your diet is on point.

However, some people have trouble getting those juicy pumps in all their workouts despite putting in hard work at the gym and keeping their diet on point.

Which is stopping them from reaching their full potential on their muscle building journey.

If that’s happening to you it might be time for you to look at increasing your Nitric Oxide levels.

Here’s the deal:

Turns out lifters are now using the best nitric oxide supplements to achieve skin tearing pumps while lifting weights.

Nitric Oxide, is found in the human body and is a molecule that plays a role in blood vessel expansion and blood flow.

There are tons of studies out there backing up the effectiveness of this molecule and the fact that by expanding the blood vessel and increasing blood flow through your body not only will your body recover faster after a workout, but also give you more of those juicy muscle pumps we all crave, which will help you build muscle faster.

How Do Nitric Oxide Supplements Work?

When you train arms, for example, that tight feeling you get in your bicep is actually blood rushing into the muscle to replenish it and provide it with energy.

Bodybuilders love that feeling because they know that they are hitting the muscle hard and the body is responding by sending blood that way to help.

The best Nitric Oxide supplements help facilitate this process so more blood can get there, faster.

That means more intense pumps and improved nutrient delivery.

Here’s how it works:

Getting more blood to the muscles in between sets means your tired muscles will recover faster and you will be able to work harder on the next set.

Since progressive overload is the cornerstone of bodybuilding, improved recovery means more weight lifted and for more reps, which in turns means more gains for you!

Additionally, many people like to perform high intensity interval training cardio which puts a lot of stress on the body.

It get’s better

With improved Nitric oxide levels in the body more oxygen and blood will get pumped around the body.

That means better performance and more calories burned in a shorter period of time which is essential if you are trying to avoid going catabolic from working out too long.

In the first week your body is in a NO loading phase but immediately you should be experiencing greater pumps.

With the best nitric oxide supplements the effects will only get better and better with time.

Best Nitric Oxide Ingredients For Muscle Pumps & Vascularity

The best N.O. products are shown to directly improve the size and intensity of your muscle pump so if you are looking to get that extra boost in the gym here are some ingredients that will help boost your levels quickly.

Look at combining these ingredients for optimal growth in nitric oxide levels.

l-arginine_powderL-Arginine – The godfather of Nitric Oxide boosters. You’ve probably heard of this amino acid before as it has a number of benefits for bodybuilders. Found mainly in nuts, fruits meats and dairy, L-Arginine has been shown to directly correlate with higher levels of nitric oxide in the body. We recommend a dosage of around 3-5 grams in order to achieve a noticeable benefit.

L-Arginine Alpha-Ketoglutarate (AAKG) – This particular L-Arginine compound can help oxidize HMB in the body. HMB is a supplement that helps build lean muscle mass.

L-Citrulline – Is another non-essential amino acid that helps with liver detoxification of ammonia. Which in turn helps support L-Arginine produce more Nitric Oxide. Recommended dose would be about 100-500mg of this one.

HTB1_28BGpXXXXcVXVXXq6xXFXXXkEurycoma Longfolia – Although not exactly a N.O. booster but more of a testosterone booster. This Malaysian traditional tonic is used to improve energy, strength, mood and libido. It has earned itself the nickname “Malaysian ginseng” as a result of its renowned energy benefits. It does this primarily by boosting testosterone levels to higher levels which aids your body’s nitric oxide production. Taking this ingredient is a very effective way to improve your performance in the gym.
