Which nitric oxide supplement is best?

Lower blood pressure and increased circulation have many positive health benefits. Nitric oxide is an important molecule for helping the body do those things. As a result, you can exercise longer with less pain and recovery time afterward. It also can help with erectile dysfunction and improve overall cardiovascular health.

Like all supplements, there are important considerations before taking nitric oxide, but if you want to improve your workout endurance, sex life or overall heart health, nitric oxide supplements could be the next step. For an overall boost in energy, the top choice is the plant-based Garden of Life SPORT + Focus Supplement.

What to know before you buy a nitric oxide supplement

How do you know if you’re deficient in nitric oxide?

Symptoms of low nitric oxide levels include high blood pressure, memory issues, low stamina and erectile dysfunction. Contributing factors to these potential symptoms include smoking cigarettes, a diet high in fat and cholesterol and little to no exercise.


Nitric oxide has many health benefits. Knowing your specific use of nitric oxide can help in choosing the right supplement. Always consult your physician before taking a supplement. Nitric oxide is primarily known for increasing blood flow and lowering blood pressure. It also promotes less sticky platelets, which is a common cause of heart attack. It also can be effective for helping with erectile dysfunction.


Nitrates are naturally found in beets, spinach, radishes, lettuce and beef. The other source is L-arginine, which is an amino acid commonly found in poultry, red meat and fish.

What to look for in a quality nitric oxide supplement

Capsule or powder

Nitric oxide supplements come in both capsule and powder forms. Capsules are easier to transport, but many nitric oxide supplements in pill form require multiple pills per day. This can deplete the quantity faster and is harder for people with swallowing issues.

You have to mix the powder with food or beverages, which isn’t always easy on the go. Nitric oxide powders also can have an unsavory taste. The powder is usually more cost-effective in the long run.

NSF certification

The National Sanitation Foundation (NSF) certifies food and sanitation products used with food. The NSF certification is recognized by most government agencies, assuring the quality of food and medicines. There is an additional certification from the United States Pharmacopeia (USP) that also signifies the same rigorous standards.

Additional nutrients

Additional ingredients are often included with nitric oxide supplements. Vitamins C and D are very common since they are part of how nitric oxide is produced in the body. The amino acid L-citrulline is often included. Keep in mind that most nitric oxide is derived from L-arginine, so if you see that ingredient listed, you will know why.

How much you can expect to spend on a nitric oxide supplement

Nitric oxide supplements cost $7-$40 depending on the form and quality certification, with higher-end powders with NSF certification priced $25-$40. Midrange nitric oxide supplements cost $15-$25 in both powder and capsule form, while low-range supplements cost $7-$15 but typically are in capsule form without NSF approval.

Nitric oxide supplement FAQ

What are the side effects of nitric oxide supplements?

A. In low doses, there are not many side effects known to be associated with nitric oxide supplements. People with low blood pressure may experience some dizziness since nitric oxide could lower their blood pressure further. High doses of nitric oxide could impact your kidneys. The research is limited, but be aware of these potential side effects.

Who shouldn’t take nitric oxide supplements?

A. Anyone who already has low blood pressure should not take nitric oxide supplements since their blood pressure could drop even lower.
