When it comes to training, finding the right balance of exercise, nutrition, and rest can make a significant difference in your results. Some athletes and gym-goers take this formula one step further by adding the best nitric oxide supplements to their routine, which may help increase blood flow and transport oxygen and nutrients to the muscles.

The belief behind nitric oxide supplements is certain ingredients produce more nitric oxide in the body which may lead to better workouts. That said, it’s important to note that nitric oxide is not actually in these supplements. Instead, the best nitric oxide supplements contain anything from beetroot powder and pine bark extract to L-citrulline and L-arginine—ingredients that may help boost nitric oxide production.

And while supplements are not designed to replace proper nutrition, rest, and exercise, the right nitric oxide supplement may benefit your health and workouts. We put together a comprehensive guide on what to look for, as well as our top picks for the best nitric oxide supplements.

How to Choose the Best Nitric Oxide Supplement


Dosage

Look for a transparent label with accurate and clear dosage amounts. Some products include a proprietary blend, making it difficult to know how much of each ingredient you’re getting. When possible, choose a nitric oxide supplement that lists the dosage for each main ingredient. In general, powders require one scoop, and capsules require three to four pills to reach the recommended dosage.

Type

Nitric oxide supplements are generally available in powder or capsules. The type you choose depends on personal preference. If taking pills is not ideal, then opt for a powder to mix into water or another drink. Remember that the powder form is flavored, and taste should factor into your decision. Most nitric oxide supplements in pill or capsule form require three to four pills to reach the maximum dosage.

Ingredients

The ingredients in nitric oxide supplements are intended to increase the level of nitric oxide in the body. Some of the more common ingredients to look for include:

  • Beets: Beetroot is a healthy superfood that is known to improve nitric oxide levels. Research suggests that beetroot juice can boost nitric oxide levels, leading to increased blood flow, gas exchange, mitochondrial biogenesis and efficiency, and strengthening of muscle contraction.
  • Arginine: L-arginine is an amino acid that is also a precursor to nitric oxide: The body changes L-arginine to nitric oxide. Therefore, supplementing with L-arginine may improve overall blood vessel health and lower blood pressure.
  • Glutathione: Glutathione is an antioxidant that helps regulate vascular function. For example, research shows an increase in nitric oxide levels in the body when glutathione and L-citrulline are taken together.
  • Citrulline: L-citrulline is an amino acid that converts to arginine. Once converted to arginine, it turns into nitric oxide, leading to a higher nitric oxide level in the body. Some research suggests that citrulline is more efficient at increasing arginine availability than arginine alone.

In addition to the ingredients listed above, nitric oxide supplements may contain pine bark extract, black pepper extract, beta-alanine, caffeine, and food-based ingredients like pomegranate, red spinach, and green leafy vegetables.

Certifications

Dietary supplements are regulated as food by the U.S. Food and Drug Administration (FDA). Because of this, it’s important to review the ingredient list and look for third-party testing and other certifications. Examples of certifications include CGMP certification, which refers to the Current Good Manufacturing Practice regulations established by the FDA.

You may also see “Informed Choice Certified” on a supplement. Products with this designation are regularly tested for prohibited substances in dietary supplements. The presence of an Informed Choice Certified mark also informs consumers that the product was made in an environment with quality systems appropriate for the stringent demands of dietary supplements and sports nutrition manufacturing.

FAQs About Nitric Oxide Supplements


Do nitric oxide supplements work?

Nitric oxide supplements are designed to work by increasing nitric oxide production in your body. However, it’s difficult to say if they work or not. Ingredients like L-arginine, L-citrulline, and beetroot powder show some success in boosting nitric oxide, while others do not have enough evidence to support their claims to increase blood flow and heighten athletic performance. Therefore, it’s best to consult your doctor or a registered dietician to determine if a nitric oxide supplement will work for you.

Who should take nitric oxide supplements?

Nitric oxide supplements might be a good addition to your supplement routine if you’re dedicated to weightlifting, athletics, or an active lifestyle. Some people may take nitric oxide supplements to help with conditions like high blood pressure, but this is best managed by your doctor. It’s always important to follow the dosage instructions. If you’re new to nitric oxide supplements, talk with your doctor before adding one to your daily routine, especially if you have a health or medical condition or taking a medication that could cause adverse reactions when taking nitric oxide supplements.

What causes low nitric oxide in the body?

According to the Journal of the American Heart Association, aging is a leading cause of low nitric oxide in the body. Cardiovascular disease is another cause of low nitric oxide in the body. Additionally, some research points to chronic renal disease as a cause of low nitric oxide production in the body.

These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.
