Which are the best nitric oxide supplements?
Nitric oxide is a compound that’s produced naturally in the cells of the body.
It helps widen blood vessels to allow for better circulation while simultaneously lowering blood pressure.
Nitric oxide supplements don’t actually contain nitric oxide but instead include compounds like L-arginine and L-citrulline that help raise the body’s production of nitric oxide.
Evidence suggests that you may experience prolonged endurance, increased strength, and bigger pumps by boosting nitric oxide levels.
In this article, we’ve rounded up the best nitric oxide supplements on the market, based on ingredients and dosage, and chosen our top pick.
Without further ado, here’s a list of the 10 best nitric oxide supplements.

Frequently Asked Questions About Nitric Oxide Supplements
Q: What Is Nitric Oxide?
Nitric oxide is a compound that the human body produces naturally and is required for various functions of human health.
The compound causes blood vessels to widen and incites hormones like insulin and human growth hormone to be released.
It also facilitates communication between cells and regulates other important functions in the body.
Q: What Are The Benefits of Nitric Oxide supplements?
Nitric oxide supplements are designed to boost nitric oxide levels in your system, which should allow you to have stronger pumps and harder workouts.
As nitric oxide is a vasodilator, it helps increase circulation, which means your muscles will receive more oxygen and nutrients.
Typically, most people experience benefits like increased muscle pumps and vascularity, increases in strength and endurance, and faster recovery times.
Q: Do Nitric Oxide Supplements Have Any Side Effects?
Nitric oxide supplements are generally considered safe to consume when taken in appropriate amounts, as defined by the manufacturer.
For most people, nitric oxide supplements do not cause side effects; however, some people may incur mild side effects like diarrhea, stomach pain, bloating, headaches, heartburn, and nausea.
If you’re thinking about taking nitric oxide supplements, then you should talk to your doctor first to make sure they’re safe to take in conjunction with any pre-existing medical conditions you have or medications you’re taking.
Q: How Do I Take Nitric Oxide Supplements?
Nitric oxide supplements typically come in capsule form, although they are also available in tablets and powder.
You can take nitric oxide supplements at any point during the day, but for best results, most brands recommend taking them approximately 30 minutes before working out as you’ll get a better pump and overall performance.
Whichever supplement you choose, we suggest starting with a lower dose to what the manufacturer recommends and slowly working your way up to a full dose once you’ve assessed your tolerance.
Q: Which Nitric Oxide Supplement Should I Choose?
When deciding which nitric oxide supplement to go for, we recommend choosing one made in an FDA-registered facility following Good Manufacturing Practices by a well-regarded brand in the supplement industry.
If you’re also going to be taking a pre-workout alongside a nitric oxide booster, then you should check that ingredients like caffeine and creatine aren’t included in the nitric oxide as they’ll most likely already be included in your pre-workout.
However, there’s no harm in taking both supplements that contain the same ingredients, but you should be aware of how much of each type of ingredient you’re ingesting daily.
Lastly, look for a supplement that provides the most bang for your buck overall, from price per serving to ingredient quantity per serving.
