Oxygen-Infused Fitness Products

Our products unite two synergistic components: O4N® Activated Stabilized Oxygen and plant-sourced liquid minerals.

We utilize our most potent stabilized oxygen formula (to enhance VO2 max) and optimize the uptake and use of critical nutrients for superior muscle performance.

This supports efficient energy use, mental clarity, and recovery from physical strains.

The Role of Oxygen in Our O4Nutrition Fitness Supplements

  • Key to Vitality

    Bioavailable Oxygen, a core ingredient in our supplements, plays a crucial role in various biological processes, including the production of cellular energy, which is key for function and recovery

  • Energy Amplified

    Our oxygen-infused formulas assist in converting nutrients into usable energy, powering up your stamina and vitality

  • Performance Optimized

    The oxygen in our supplements helps enhance muscle function and endurance, empowering you to extend and intensify your workout sessions

  • Swift Recovery

    Leveraging oxygen's healing properties, our supplements facilitate tissue repair, promote faster healing, and help clear lactic acid to reduce muscle fatigue and soreness

  • Boosted Immunity

    Our oxygen-enriched supplements support a robust immune function, fostering a more effective immune response.

  • Maximized Bioavailability

    The oxygen infusion in our supplements ensures increased bioavailability, promising maximum efficiency and benefits from each dose.

How Does O4Nutrition Boost Performance?

  • ENERGY GENERATION

    Optimal performance needs efficient energy. Aerobic metabolism - the top energy process - uses a steady oxygen flow to transform glucose into muscle energy.

  • OXYGEN SHORTFALL

    In high-intensity exercise, lungs may fail to provide enough oxygen for muscles, leading to a less efficient anaerobic metabolism. This switch results in lactic acid build-up, causing muscle pain and tiredness.

  • PERFORMANCE BOOST

    O4Nutrition can help. By elevating blood oxygen, it promotes more energy production, extends aerobic metabolism, reduces lactic acid, and enhances performance.

I drink this at night a few hours before bed. The first week I didn’t notice much of a difference, but after week two I noticed how much deeper I’m sleeping! How much more relaxed I am at night. I will definitely be keeping this in my routine.
