Welcome to ImmuneO2
ImmuneO2 uses adaptive contrast to restore oxygen delivery to immune cells, addressing the foundational oxygen deficit that underlies compromised immune function.

How Oxygen Combats Inflammation at the Source
Immune function is heavily dependent on oxygen. Immune cells require adequate oxygen supply to identify threats, mount responses, and clear pathogens effectively. When oxygen delivery drops chronically, immune performance drops with it — and people become more susceptible to illness and slower to recover.
ImmuneO2 uses adaptive contrast training to directly improve oxygen delivery to immune cells, restoring the conditions for normal immune function. For people dealing with chronic illness, post-viral fatigue, or generally compromised immunity, this represents a foundational intervention rather than a symptomatic one.
Inflammation thrives in low-oxygen tissue. Adaptive contrast floods hypoxic tissue with oxygenated plasma — interrupting the inflammatory cycle at its source.
Key Takeaways
- Immune cells require oxygen to perform their core functions
- Chronic oxygen delivery deficits suppress immune performance
- ImmuneO2 protocol is designed specifically to restore immune cell oxygenation
- Relevant for post-viral recovery, chronic illness, and general immune support
“LiveO2 changes what you breathe while you exercise. That one change produces outsized results in a fraction of the time.”
— Mark Squibb, CEO & Inventor of LiveO2Common Questions
LiveO2 is an oxygen training system that changes what you breathe while you exercise. It uses Adaptive Contrast — switching between oxygen-rich and oxygen-reduced air — to dramatically increase oxygen delivery to your cells in about 15 minutes.
About 15 minutes. You exercise on a bike or treadmill while the system manages the oxygen and altitude contrast automatically. Most people feel the effects within their first session.
Adaptive Contrast is LiveO2’s core technology. It switches between high-oxygen and low-oxygen air during exercise. The low-oxygen phase opens your blood vessels. The high-oxygen phase floods them with saturated plasma. The result is dramatically more oxygen reaching your tissues. Full explanation here.
LiveO2 uses the same oxygen you breathe every day — just in higher concentrations, combined with controlled exercise. It is a non-invasive training system. Consult your healthcare provider if you have specific medical concerns.
Athletes, practitioners, biohackers, and everyday people. LiveO2 systems are used in clinics, gyms, training facilities, and homes across the country. See how one doctor discovered it.
