The 25 Top-Rated NO Supplements to Enhance Muscle Strength, Increase Endurance, and Aid Recovery

Why would you want to take a nitric oxide supplement? To understand the benefits, you should first understand what nitric oxide is and the role it plays in the body. Enzymes in your body break down arginine, an amino acid, producing a gas, nitric oxide (NO), which is used for communication between cells. Arginine is found naturally in foods such as spinach, turkey (white meat), shrimp, crab, and sesame seeds. Nitric oxide actually plays a role in a variety of processes, such as controlling blood circulation and regulating the activities of the brain, kidneys, liver, lungs, and other organs.

For workout purposes, NO is involved in the release of hormones and adrenaline. Thanks to its effects on blood circulation, it’s believed to help with blood flow during and after workouts, delivering more nutrients to your muscles which can aid in growth and recovery. Many people believe that NO helps them workout longer and harder and recover faster. It’s also said to increase the availability of energy and increase the utilization of glucose. All of these possible effects are beneficial to the athlete who wants to increase their endurance and speed recovery after their toughest workouts.

Nitric oxide supplements typically contain one or more forms of arginine, the amino acid that’s a precursor to nitric oxide in the body. The most popular form is arginine alpha-ketoglutarate. So, if you’re looking to ramp up your fitness and get more results by working out harder and longer and reducing recovery time, a nitric oxide supplement might be just what you’re looking for. To help you narrow your options, we’ve rounded up 25 top-rated NO supplements, based on ingredients, reviews, and other considerations. Our picks are listed below in alphabetical order. Ratings information is based on Amazon reviews and is current at the time of this writing.

Of course, as with any supplement, you should discuss taking a nitric oxide supplement with your healthcare provider to ensure that these supplements will not put your health at risk through side effects or by interacting with other medications and supplements you’re taking.
