Does CircO2 really work? How does CircO2 promote nitric oxide production and circulation? Keep reading to find out how CircO2 works and what the supplement does today in our review.
What is CircO2?
CircO2 is a blood circulation supplement available exclusively online.
According to Advanced Bionutritionals, the Norcross, Georgia-based company behind the supplement, CircO2 is “proven to boost nitric oxide 200% higher than arginine in just minutes.”
Each quick-dissolving tablet of CircO2 contains a blend of natural ingredients to promote nitric oxide production. Nitric oxide, or NO, is a molecule your body naturally produces to widen blood vessels and promote circulation. Higher levels of NO are associated with better blood flow and reduced blood pressure.
CircO2 is available through the Advanced Bionutritionals online store, where it’s priced at around $49.95 per box. All purchases come with a 90 day moneyback guarantee.
CircO2 Benefits
According to Advanced Bionutritionals, CircO2 can promote a range of benefits within 20 minutes, including:
- Boost energy
- Sharpen memory
- Increase stamina
- Enhance sexual performance
- Help support healthy blood pressure
How Does CircO2 Work?
CircO2 works by targeting nitric oxide (NO), a molecule in your body linked to blood flow. Your body produces NO on its own. However, taking certain foods or supplements can increase your body’ s natural production of NO.
Nitric oxide is critical for overall health and wellness. It helps promote healthy blood flow by widening and relaxing your blood vessels. It makes it easier for blood to flow throughout your body, which can help with blood pressure, energy, relaxation, heart rate, and sexual health, among other benefits.
CircO2 comes in the form of a dissolvable tablet. You let the tablet dissolve on your tongue, and your body absorbs the active ingredients immediately through the sensitive skin around your mouth. You swallow the remaining tablet, allowing the ingredients to continue working throughout your body.

What Does Nitric Oxide Do?
Advanced Bionutritionals describes nitric oxide as a “miracle molecule” for its ability to promote a healthy heart, sharp memory, and nonstop energy.
When your body produces ample nitric oxide, you tend to have lower blood pressure, better blood flow, improved energy, and sharper physical and cognitive performance, among other benefits.
Here are some of the effects nitric oxide has in your body, according to Advanced Bionutritionals:
- Tells your arteries to relax, helping them open wider and causing blood to flow freely to promote healthy blood pressure and reduce cardiovascular health risks
- Fuels your body with long-lasting, sustainable energy for better stamina and performance
- Wakes up your brain to send and receive signals more quickly
- Boosts the formation of bone and slows bone breakdown
- Signals your immune system to kill bacteria, viruses, and other harmful invaders
- Promotes mood and overall sense of wellbeing, supports healthy muscle and joint recovery, and enhances blood flow to sexual organs for better performance, among other benefits
- Many of these benefits are linked to blood flow. Nitric oxide promotes better blood flow, and better blood flow is associated with overall health and wellness throughout your body.
Nitric Oxide Production Drops with Age
Your body produces nitric oxide on its own. So why do you need a nitric oxide supplement?
Unfortunately, nitric oxide production decreases with age.
Your body produces the maximum amount of nitric oxide in your 20s. By the time you’re in your 40s, however, they’re at just 50% of their previous levels. In your 60s, your body is producing just 15% of the nitric oxide it produced at its peak. These lower nitric oxide levels can contribute to higher blood pressure and lower energy – symptoms many associate with aging.
Falling nitric oxide production is linked to your endothelium, which is the lining inside all of your blood vessels. Your endothelium is crucial for delivering oxygen and nutrients throughout your body. It also produces nitric oxide, helping to keep blood vessels flexible and wide to promote good blood flow.
When you’re young, your endothelium is healthy and active. It provides a steady current of nitric oxide to push oxygen and nutrients anywhere in your body they need to go.
When you get older, however, your endothelium doesn’t produce as much nitric oxide. You might feel increased symptoms of aging. Your energy could drop. Your blood pressure could rise. CircO2 works by counteracting this effect using natural ingredients, promoting nitric oxide production at any age.

CircO2 Ingredients
CircO2 contains a blend of natural ingredients to promote your body’s natural nitric oxide production.
Many of the ingredients in CircO2 work by giving your body the building blocks of nitric oxide. Beetroot powder, one of the active ingredients in CircO2, is rich with nitrates, for example, that are linked to nitric oxide production. By taking the nitrates in CircO2 daily, you can boost your body’s natural NO production.
Here are all of the active ingredients in CircO2 and how they work to promote NO production and circulation:
L-Citrulline: One of the most important ingredients in CircO2 is L-citrulline. The amino acid is found in many preworkout supplements and natural energy boosters for its ability to widen blood vessels and promote healthy blood flow. Today, CircO2 uses the same amino acid to increase nitric oxide throughout your body. According to Advanced Bionutritionals, L-citrulline is backed by “a growing amount of research” linking it to healthy blood pressure levels. Other studies have linked L-citrulline to better bedroom performance. Some athletes take L-citrulline for energy, stamina, and brainpower. For all of these reasons and more, L-citrulline is one of the most important ingredients in the CircO2 formula.
Beetroot Powder: CircO2 contains beetroot powder to help you think clearly and support physical and cognitive performance. According to Advanced Bionutritionals, the beetroot powder in CircO2 is “able to open up your blood vessels and increase blood flow,” boosting energy and supporting overall cardiovascular health. And, instead of eating dozens of beets per day, you can get a single serving of CircO2’s dissolvable tablet.
Hawthorn Berry: Hawthorn berry is rich with natural antioxidants like vitamin C. The small, red berry has a long history of use in traditional medicine. Today, we know it works as a traditional remedy because it’s rich with vitamin C, one of nature’s best antioxidants. Like other antioxidants, vitamin C works throughout your body to promote healthy inflammation. It neutralizes the effects of frere radicals and helps support inflammation, which is linked with disease and illness. Hawthorn also has an additional effect: according to Advanced Bionutritionals, the hawthorn berry in the formula helps your body absorb more L-citrulline and beetroot powder than it normally would.
Vitamin B12: CircO2 contains vitamin B12, a popular vitamin for energy and performance. Many people – especially vegans and vegetarians – are deficient in vitamin B12 because there are few plant-based sources of the vitamin. Each serving of CircO2 contains 1,000mcg of vitamin B12 to increase nitric oxide levels and support brain, nerve, and muscle function.
Vitamin C: CircO2 contains vitamin C, a powerful antioxidant linked to nitric oxide levels. It stimulates the activity of an enzyme linked to nitric oxide, helping to increase overall nitric oxide. Vitamin C is also naturally present in hawthorn berry and certain other ingredients in CircO2, and it contributes to the active effects of the supplement in multiple ways.
Magnesium: About 80% of American adults are deficient in magnesium, which is a problem because magnesium is critical for muscle function and blood flow. Your body needs magnesium to promote healthy heart rhythm. Calcium also keeps calcium from building up in your brain, heart, and joints – all of which are linked to health risks. For all of these reasons and more, many people take a magnesium supplement daily for health and wellness.
Overall, the unique combination of ingredients in CircO2 can purportedly boost nitric oxide “200% higher than arginine” alone in just minutes. Sure, you could take arginine for blood flow. However, CircO2 combines citrulline – which works similar to arginine – with other natural ingredients to promote healty blood flow and NO levels.

Scientific Evidence for CircO2
Most supplements aren’t backed by specific scientific evidence. Clinical trials are expensive, and supplement companies may not want to invest in them. However, CircO2 is backed by clinical trials on the specific blend of ingredients.
Here’s how one study worked using a supplement with the same ingredients and combinations in CircO2:
Researchers tested a formula that has the same ingredients in the same combinations as you get in CircO2, including the same quick-dissolving delivery system.
Researchers gathered a group of people with high blood pressure, then measured blood pressure before and after taking the supplement.
20 minutes after taking the supplement, researchers found participant’s systolic blood pressure had dropped by 4 points and diastolic blood pressure had dropped by 5 points.
After 60 minutes, researchers found these numbers had fallen even further. According to Advanced Bionutritionals, “even their blood vessels had gotten healthier” after 60 minutes.
The individual ingredients in CircO2 are also backed by scientific evidence. A 2019 review analyzed the effects of citrulline on blood pressure, for example, and found a significant connection between the two. Researchers found supplementation of 3,000mg to 9,000mg of L-citrulline per day was associated with an average drop of 4.10 mm Hg for diastolic and 2.08 mm Hg for diastolic blood pressure.
Some people take beetroot juice or beetroot extract daily for blood pressure. A 2018 study published in Biomolecules found dietary nitrate could help control arterial blood pressure in adults with pre-hypertension. Based on the results of the study, researchers concluded beetroot could be used to complement diet and exercise changes to control high blood pressure.
Some studies suggest vitamin B12 deficiency is a risk factor for cardiovascular disease in vegetarians. A 2015 study published in the American Journal of Preventive Medicine, for example, found a connection between vitamin B12 deficiency and high blood pressure, high cholesterol, and other risk factors for heart disease. Because of this connection, people deficient in vitamin B12 – including many vegans and vegetarians – may consider taking a vitamin B12 supplement.
Overall, CircO2 contains a blend of science-backed ingredients, and the supplement as a whole has been studied to verify it works. The formula was also created by medical professionals. All of this evidence gives CircO2 an edge over competing NO supplements.
