What Is CircO2?
CircO2 is a natural nitric oxide–enhancing lozenge designed to improve circulation, oxygen delivery, and cardiovascular performance. As we age, nitric oxide levels can drop by up to 75%, causing symptoms like:
- Low energy and fatigue
- Cold hands and feet
- Poor blood flow
- Brain fog or lack of clarity
- Slower physical performance
CircO2 combines beetroot, hawthorn, vitamin C, antioxidants, and nitric oxide precursors to support healthy vasodilation. This allows more oxygen and nutrients to reach the heart, muscles, and organs — leading to improved vitality and daily performance.
Key Benefits
- Supports increased nitric oxide production for healthy circulation
- Boosts energy and stamina without caffeine or stimulants
- Promotes healthy blood pressure levels already within a normal range
- Enhances oxygen delivery and athletic endurance
- Improves focus and daily mental clarity
- Supports healthy aging and cardiovascular function
How CircO2 Works
CircO2 works by delivering nitric oxide precursors directly into the bloodstream through oral absorption. Unlike capsules, the lozenge form allows nutrients to bypass the digestive system for faster activation.
Science Behind It (Healthline / Mayo Clinic Style)
- Nitric Oxide Boosting: Ingredients help trigger vasodilation, expanding blood vessels.
- Improved Oxygen Delivery: Better blood flow means increased oxygen to tissues.
- Antioxidant Protection: Helps reduce oxidative stress linked to cardiovascular decline.
- Healthy Circulation: Supports heart function and metabolic efficiency.
