The Best Nitric Oxide Supplements of 2020

Nitric oxide (NO) from supplements and food may not only help to boost your performance at the gym, but they may also be used to help lower blood pressure. 1 Nitric oxide (or lack thereof) may also play a role in risk of erectile dysfunction, since nitric oxide plays a role in penile erection. 2 3 While many people are able to get enough of this nutrient in their diet, for others, supplementing has beneficial effects. 

Finding the best nitric oxide supplement for your health and wellness needs means reading reviews, studying product features, and diving into the ins and outs of available flavors and formulas. With the right nitric oxide supplement, boosting the body’s NO levels naturally can become a quick, over-and-done-with task.

Who Should Buy a Nitric Oxide Supplement

A nitric oxide supplement is an ideal choice for those who work out regularly and want to boost their performance. Some research shows that nitric oxide and consumption of nitrate-rich vegetables (like beets) may reduce arterial stiffness, reduce blood pressure, and improve carotid artery blood flow. 5 6 7 Nitric oxide is beneficial in this case due to the improved heart function it provides, which in turn helps to enhance tolerance to exercise and oxygen delivery to muscles during exercise. 8 9 10

A nitric oxide supplement can also be helpful to men suffering from mild to moderate erectile dysfunction. One study found that erectile dysfunction patients were found to have low levels of L-arginine and L-citrulline. 11 Studies have shown that the enhanced blood flow provided by NO supplements can help to reduce ED symptoms. 12

Finally, women who experience high blood pressure in pregnancy or dangerous preeclampsia, may also benefit from taking a nitric oxide supplement. However many studies have been too small to make concrete conclusions. 13 Research has shown that pregnant women who took certain supplements, such as L-arginine, may recieve benefits in preventing preeclampsia. 14 Pregnant women should always talk to their OBGYN before taking over the counter supplements.

Important Features to Consider

Not all nitric oxide supplements are created equal. A nitric oxide supplement should be safe, effective, and easy to take. Here’s what to consider when evaluating the options in search of the best nitric oxide supplement for your needs:

  • Format. Arguably the most important factor when shopping for a nitric oxide supplement is the format. There are powders, tablets, and capsules available, but all help achieve the same end result — enhanced blood flow in the body.
  • Ingredients. Another important consideration when it comes to choosing the best nitric oxide supplement is the ingredients. The two most common nitric oxide supplement ingredients are L-arginine — an amino acid naturally found in red meat, dairy products, poultry, and legumes, and/or L-citrulline — a non-essential amino acid found in pumpkin, cucumber and watermelon. Beyond that, nitric oxide supplements may include other vitamins and minerals, as well as flavorings.
  • Dosage. There’s no sense choosing a NO supplement that has you popping multiple capsules throughout the day, or mixing several beverages. Find a product that has a dose that is manageable for you to take on a regular basis.
  • Labels. Keep in mind that most over the counter supplements are not regulated by the FDA. This leaves the burden of ensuring safety on the consumer, so carefully check information of all ingredients of a supplement before purchasing. Also, look into the reliability of the manufacturer before buying any supplement. Quality manufacturers should list all ingredients and have access to lab tests and studies that show their products are safe and effective.
  • Price point. Finally, consider how much you are willing to spend on a nitric oxide supplement. Nitric oxide supplements vary in price from $10-$50 or more for a month’s supply. Don’t forget to factor in the number of servings per container when breaking down the overall cost of a NO supplement. If a bottle contains 120 capsules, but you need to take 4 capsules daily, it might not be the better option, even if it’s less expensive than the 60 capsule bottle that only requires one capsule per day.

Frequently Asked Questions

What is a nitric oxide supplement and how does it work?

A nitric oxide supplement typically contains L-arginine — an amino acid naturally found in red meat, dairy products, poultry, and legumes, and/or L-citrulline — a non-essential amino acid found in pumpkin, cucumber and watermelon. The body uses nitric oxide for communication between cells, and it is an essential part of a variety of bodily processes, including controlling blood circulation and regulating the activities of several organs.

Nitric oxide is also involved in workouts, aiding in cardiorespiratory endurance and increasing time to exhaustion in athletes. 15 It’s believed NO helps with blood flow during and after workouts, as well as increasing the utilization of glucose. 16 By supplementing with nitric oxide, you’re increasing the levels of this gas within the body.

What foods are high in nitric oxide?

Foods that are high in the components of nitric oxide include red meat, dairy products, poultry, seafood, nuts, legumes, nuts, beets and leafy greens. 17 Adding these foods to your diet on a regular basis can help to naturally boost your levels of nitric oxide. 18 

What are the benefits of nitric oxide supplements?

Researched benefits of nitric oxide supplements include reduced arterial stiffness, reduced blood pressure, and improved carotid artery blood flow. It also helps enhance tolerance to exercise and oxygen delivery to muscles during exercise. 19 20 The enhanced blood flow provided by NO supplements can also be beneficial to those with mild to moderate erectile dysfunction, as well as reducing high blood pressure in pregnancy. 21 22

What are the side effects of nitric oxide supplements?

While many people tolerate nitric oxide supplements without any issues, there are some possible side effects to be aware of. Side effects of nitric oxide supplements include nausea, diarrhea, stomach pain, bloating and urine discoloration (usually from beetroot-based supplementation) 23 24 Taking a NO supplement is also contraindicated in those with herpes, and following a heart attack.

Asian Pac J Trop Med. 2018;11(6):381-386. doi:10.4103/1995-7645.234766[/efn_note] 25 Always speak with your doctor before taking any supplement to ensure it will not interfere with an existing condition or any medications you may be taking.
