Are you looking for a natural supplement that may help build more muscle, but also improve your recovery time after a workout? Do you want to streamline your body’s ability to function more efficiently on a cellular level? Perhaps you want to lower your blood pressure, improve your immune function, or protect your brain and heart health.

If so, you may be wondering what you can do…

Simply adding a top nitric oxide supplement to your daily routine may be the answer.

Nitric oxide (NO) pills are inexpensive, at around $11 to $27, and simple way to help boost the effectiveness of your workouts so you are not wasting any precious time training hard and not getting the results you are seeking.

There is nothing worse than eating the right way and training hard, only to see painfully slow growth or lackluster results that leave you feeling defeated and frustrated.

The other effects of increased NO in the body are added benefits for overall health as well.

In this article and review, we will take a look at:

  • What NO supplements are
  • How they work
  • The benefits of nitric oxide supplements
  • The side effects of nitric oxide supplements
  • How you should use the supplements correctly

We will also discuss the top nitric oxide supplements available, so you can achieve your best body and feel the healthiest you have in years.

What is NO?

 Nitric oxide is a gas produced by your body naturally and plays a role in just about every cell function. Nitric oxide is responsible for helping your cells communicate with each other. NO also controls proper blood circulation and regulates how your organs, such as your brain, lungs, stomach work.

What are the benefits of Nitric Oxide?

Taking Nitric Oxide SupplementsNO is a popular way to control high blood pressure and help maintain a properly functioning cardio vascular system.

Essentially, NO produced by the body is generated in the vasculature and then spreads to the muscle underneath causing the muscles in that area to relax. As a result, blood pressure drops, and an increase of blood flow and oxygen move to the area.

NO plays an important part in brain function as well. NO can help a variety of neurological processes as both underproduction and overproduction can have major effects on memory and diseases like Parkinson’s, Alzheimer’s, and conditions like depression. Patients who have less NO production in the body than average receive less blood flow to their brain, which can increase inflammation and stress in the brain.

Nitric oxide can also improve your immune system since certain cells in the body generate nitric oxide and help your body defend itself against a wide variety of pathogens and bacteria. For instance, it controls infectious diseases, tumors, and chronic degenerative diseases such as kidney disease due to its reaction partners.

Although there are much less evidence and research on NO and how they affect and improve workout performance, muscle growth, and recovery time, we are seeing more information popping up in studies that claim nitric oxide supplements benefits this as well.

A study suggests nitric oxide supplements can increase stamina and workouts last 20% longer

One study conducted by the University of Exeter found that supplements that boost the production of NO in the body have a significant impact on stamina during high-intensity workouts. In fact, the study found it helped athletes workout 20% longer and it decreased their race times by 1-2%.

Overall, nitric oxide has been proven to help in the following areas and shows the many reasons why you should consider taking a nitric oxide supplement:

  • Lowers blood pressure and helps maintain a healthy cardio vascular system.
  • Improves brain function.
  • Improves the immune system.
  • Improves workout performance and stamina during workouts.

Tip

If you want to add a nitric oxide supplement into your daily routine, it is as simple as finding your preferred supplement and taking the pill with food in the morning. Viola, you will begin to reap its benefits!

How do nitric oxide supplements work?

Wondering How Nitric Oxide Supplement WorksYou may now be wondering:

How do these little pills actually work?

Nitric oxides supplements do not actually contain nitric oxide…What?

Rather, they contain amino acids that convert to NO in your body. The best nitric oxide supplements contain arginine or L-arginine. Taking this dietary supplement gives your body a push to produce more nitric oxide than it normally does in the endothelial cells.

Once your body can produce more NO than normal, your blood flow will increase and more oxygen is carried to the muscles that are working during your workout.

Therefore, nitric oxide supplements are believed to help you work out for an extended period and help speed up muscle recovery after your workout. It is important to note that although there are some studies that show NO supplements improve a workout, there are also other studies that found NO has little effect on workout stamina. Conflicting information like this is typical in areas in the scientific community that have not been abundantly researched.

Some claim this process fills your muscles with blood, which help make your muscles look more pronounced. However, there is still debate in the scientific community whether or not this is actually what happens.

Types of nitric oxide supplements

Although there are varying forms of nitric oxide pills, they all contain one or more forms of arginine. As we discussed above, this ingredient is a precursor for the production of nitric oxide in the body.

L-arginine, L-citrulline, citrulline malate, nitrate, and flavonoids are common ingredients found in the top nitric oxide supplements to help boost the production of NO in the body.

Side effects of nitric oxide supplements

Side Effects of Nitric Oxide SupplementsAs with any supplement, there are side effects you should be aware of before you start a new supplement regimen.

Changes in blood pressure are one of the most common side effects. Decreased blood pressure is common since the supplement affects your blood vessels. Symptoms of low blood pressure include lightheadedness, nausea, vomiting, and headaches. If you suffer from blood pressure issues, speak with your doctor before you begin a NO supplement regimen.

Stomach issues like stomach aches, cramps, increased number of stools, and bloating happen as well. You might be able to counteract some of these side effects if you take the supplements with meals. Again, you should speak to your physician advice and the appropriate way to take supplements based on your personal health background.

Electrolytes may change with the use of a NO supplement as well. NO can change the chemical environment of your body, especially if you have kidney or liver disease. NO can create high potassium, chloride, urea nitrogen, creatinine and low sodium and phosphate levels, which can drastically affect electrolyte levels.

Nitric oxide supplements may increase bleeding as well.

Common side effects from nitric oxide supplements:

  • Changes in blood pressure.
  • Stomach issues – bloating, cramps, pain, nausea, vomiting.
  • Changes in electrolyte levels.
  • Increased bleeding.

How to take nitric oxide supplements

 Depending on how you plan you use nitric oxide and what use you are using it for (to lower blood pressure, increase immune function, etc.) or to use it is a muscle or workout enhancers, the dosage and recommended supplementation will vary. It will also vary depending on your age, gender, and body weight.

In order to find the proper dosage for your needs and your body, your best bet is to speak with your trusted healthcare professional in order to determine a safe level of nitric oxide supplementation.
