CircO2 Supplement

Product Details

The manufacturer identifies CircO2 as a quick-dissolve nitric oxide supplement and states that Advanced Bionutritionals products are manufactured in the USA from globally sourced ingredients.

What Is CircO2?

CircO2 is a quick-dissolve dietary supplement from Advanced Bionutritionals. Each box contains 30 tablets, and the current Supplement Facts panel lists one tablet as a serving. The manufacturer markets it for supporting healthy nitric oxide production and general circulation.

The formula combines vitamins, a mineral, botanical ingredients, an amino acid, and sodium nitrite. Its active components include vitamin C, vitamin B12, magnesium, beet root powder, hawthorn berry extract, L-citrulline, and sodium nitrite. The last four ingredients are grouped within a proprietary nitric oxide blend.

Who May Consider CircO2?

Adults interested in nutritional support for healthy nitric oxide production and normal circulation may consider this type of formula. It may appeal to consumers who prefer a quick-dissolve tablet instead of a conventional capsule or powder.

People who use blood-pressure medicines, cardiovascular medicines, or other supplements that may affect circulation should seek professional guidance first. Anyone experiencing persistent dizziness, weakness, chest symptoms, unusual shortness of breath, or other unexplained symptoms should obtain medical evaluation rather than relying on a dietary supplement.

How May CircO2 Support General Wellness?

Nitric oxide acts as a signaling molecule involved in normal blood-vessel function. Beetroot provides naturally occurring nitrate compounds, while L-citrulline is converted in the body to arginine, which can participate in nitric oxide production. Research on these ingredients varies by dose, preparation, and population.

Vitamin C contributes antioxidant activity, vitamin B12 supports normal red blood cell formation and neurological function, and magnesium is involved in normal muscle and nerve function. The manufacturer includes hawthorn berry, beet root, L-citrulline, and sodium nitrite within its nitric oxide blend.

Evidence from individual ingredients should not be treated as proof of identical effects from the finished CircO2 formula.

Supplement Facts

Serving Size: 1 Tablet
Servings Per Container: 30

Proprietary Nitric Oxide Blend contains:

• Beet root powder (Beta vulgaris)
• Hawthorn berry extract (Crataegus laevigata)
• L-citrulline
• Sodium nitrite

The label discloses only the combined 420 mg blend amount. It does not provide individual quantities for the four ingredients inside the blend.

Active Ingredients

The current label combines three disclosed nutrients with a 420 mg proprietary nitric oxide blend.

• Vitamin C

Vitamin C is provided as magnesium ascorbate and ascorbic acid at 100 mg per tablet. This water-soluble vitamin contributes antioxidant activity and supports normal collagen formation and immune function.

• Vitamin B12

Vitamin B12 is supplied as methylcobalamin at 1,000 mcg per tablet. It contributes to normal red blood cell formation, DNA synthesis, and neurological function within the body.

• Magnesium

Magnesium is provided as magnesium ascorbate at 4 mg per tablet. This essential mineral participates in normal muscle and nerve function, energy production, and numerous enzyme reactions.

• Beet Root Powder

Beet root powder, listed as Beta vulgaris, forms part of the 420 mg proprietary blend. Beets naturally contain nitrates that the body can convert through pathways involved in nitric oxide production.

• Hawthorn Berry Extract

Hawthorn berry extract, listed as Crataegus laevigata, is included within the proprietary blend. The individual amount is not disclosed, and evidence for hawthorn-related cardiovascular benefits remains limited or inconsistent.

• L-Citrulline

L-citrulline is included within the 420 mg proprietary blend, but its individual quantity is undisclosed. The body can convert citrulline to arginine, which then participates in nitric oxide production.

• Sodium Nitrite

Sodium nitrite is the final listed component of the proprietary nitric oxide blend. Its individual amount is not disclosed, so the label does not allow dose-specific assessment of this ingredient.

Other Ingredients And Allergens

The current label lists:

• Mannitol
• Xylitol
• Modified cellulose
• Microcrystalline cellulose
• Plant-based magnesium stearate
• Natural flavor and color
• Silica
• Stevia leaf extract

No capsule material applies because CircO2 uses quick-dissolve tablets. A specific common-allergen declaration is not visible on the current Supplement Facts image, so allergen-free status should not be assumed.

Potential Benefits

• May support healthy nitric oxide production through its nitrate- and amino-acid-containing formula.
• Designed to support normal circulation as part of general cardiovascular wellness.
• Provides vitamin C for normal antioxidant and collagen-related functions.
• Contributes vitamin B12 involved in neurological function and red blood cell formation.
• Contains magnesium involved in normal muscle, nerve, and metabolic functions.

Important Limitations

• The individual amounts of beet root, hawthorn berry, L-citrulline, and sodium nitrite are hidden within a 420 mg proprietary blend.
• Research involving beetroot, citrulline, or hawthorn separately does not establish equivalent effects for the complete CircO2 formula.
• Long-term safety information for hawthorn is limited, according to NCCIH.
• Complete product-specific allergen, vegan, vegetarian, and third-party testing information is not publicly disclosed on the current label.

How To Use?

The available Supplement Facts label and manufacturer materials provide the following verified information:

1. Serving size: One quick-dissolve tablet.
2. The manufacturer describes CircO2 as a tablet or lozenge intended to dissolve in the mouth.
3. The official campaign advises allowing the lozenge to dissolve completely before swallowing; it also states that partially dissolving and then chewing is acceptable.
4. The current Supplement Facts image does not state whether the tablet should be taken with food or water.
5. Complete storage and maximum daily serving instructions are not visible on the available Supplement Facts image. Follow the directions on the physical package.

The campaign page separately discusses taking CircO2 once or twice daily, but consumers should follow the current product packaging rather than treating promotional guidance as a replacement for label directions.

Warnings And Precautions

• The manufacturer specifically advises people with low blood pressure to consult their physician before using CircO2.
• Ask a healthcare professional before combining the supplement with medicines that affect blood pressure or circulation.
• Hawthorn may interact with medications, so people taking prescription drugs should obtain professional advice.
• Pregnancy and breastfeeding safety is not established on the available product label; NCCIH notes limited safety information for hawthorn during these periods.
• Suitability for children is not publicly disclosed. Do not assume the adult supplement is appropriate for children.
• Check the physical package carefully if you have allergies because a complete allergen declaration was not found on the displayed label.
• Stop using the product and obtain medical advice if an unexpected or significant reaction occurs.
• Do not use damaged or visibly tampered packaging.

Possible Side Effects And Interactions

Tolerance can vary between individuals. Hawthorn can cause effects such as dizziness, nausea, vomiting, diarrhea, or muscle pain in some users, and it may interact with medicines. Citrulline has caused stomach discomfort in some studies and can influence blood-vessel dilation.

The manufacturer specifically advises people with low blood pressure to speak with a physician before using CircO2. Because individual amounts inside the 420 mg proprietary blend are not disclosed, dose-specific interaction assessment is limited. Consult a pharmacist or healthcare professional if you use prescription medication or manage a medical condition.
