What is CircO2?
CircO2 is a dietary supplement formulated to support healthy blood flow, energy levels, and cardiovascular function. It uses a unique blend of natural ingredients designed to boost nitric oxide production in the body, which is crucial for relaxing blood vessels and improving circulation.
This supplement is often marketed toward individuals experiencing low energy, poor stamina, or age-related cardiovascular concerns.
This supplement comes in dissolvable tablet form, making it easy to use without water. When taken daily, it aims to naturally improve oxygen delivery throughout the body, which can enhance physical performance, brain function, and heart health.
Unlike many synthetic stimulants, CircO2 works with the body’s own chemistry to promote vitality. Many users turn to CircO2 for its potential anti-aging benefits, as better circulation and oxygenation can influence overall wellness.
Whether you’re looking to support heart health, mental clarity, or stamina, CircO2 offers a non-invasive, natural option for promoting a more active, energetic lifestyle.
How Does CircO2 Work?
CircO2 is designed to naturally support the body’s ability to produce nitric oxide, a vital molecule that helps relax and widen blood vessels.
As we age, the body’s nitric oxide production decreases, which can lead to poor circulation, reduced energy, and slower cognitive function. CircO2 works by stimulating the body’s own nitric oxide pathways, helping to restore optimal blood flow.
By promoting improved blood circulation, CircO2 supports the delivery of oxygen and nutrients to muscles, organs, and tissues. This can lead to enhanced physical endurance, mental clarity, and heart health.
Better circulation also helps reduce fatigue and supports healthy blood pressure levels, making it ideal for people seeking natural cardiovascular support.
Additionally, CircO2 helps optimize energy levels without relying on caffeine or stimulants. Users often report feeling more alert and active throughout the day. Over time, regular use may support overall vitality, better stamina, and improved quality of life, especially for those in midlife and beyond.
Ingredients of CircO2
Vitamin C
Vitamin C, in the form of magnesium ascorbate and ascorbic acid, is an essential nutrient that supports immune function and helps protect cells from oxidative stress. It also promotes collagen synthesis for healthy skin, cartilage, and bones.
Vitamin B12
This form of Vitamin B12, including methylcobalamin and cyanocobalamin, plays a crucial role in nerve function, red blood cell formation, and DNA synthesis. It also supports energy levels and cognitive health, especially in individuals with B12 deficiencies.
Proprietary Nitric Oxide Blend
The proprietary blend contains ingredients like beetroot powder, hawthorn berry extract, L-citrulline, and sodium nitrite. These components work together to enhance nitric oxide production, improve circulation, and support heart health by widening blood vessels and increasing blood flow.

How to Use CircO2?
Take One Lozenge Daily: Place one CircO2 lozenge in your mouth each day, ideally in the morning for all-day benefits.
Let It Dissolve Slowly: Do not chew or swallow—let the lozenge fully dissolve under your tongue for optimal absorption.
Avoid Brushing Immediately After: Wait at least 10–15 minutes before brushing your teeth, as some ingredients may interact with toothpaste.
Stay Consistent: For best results, use CircO2 daily at the same time to support steady nitric oxide production.
