BrainO₂™

Your brain burns 20% of your body’s total oxygen just to function. When that supply drops — from aging, illness, injury, or poor circulation — cognition, mood, and mental energy all suffer. But low oxygen delivery isn’t something most doctors test for, because it doesn’t fit neatly into a standard diagnosis or insurance billing code.

Oxygen therapy for cognitive conditions is largely absent from mainstream treatment protocols. It’s not that it doesn’t work — it’s that there’s no reimbursable category for it. So most patients never hear about it.

LiveO2 isn’t a medical device and doesn’t require a prescription. It’s a training protocol that restores what your brain has been missing — deep oxygen delivery to the areas that need it most. That’s what makes it accessible outside the insurance system entirely.

Standard tests like MRIs and blood work check your brain’s shape, not how well it’s working. They don’t measure how much oxygen actually reaches your brain cells. So your tests look fine, but your brain still doesn’t feel right.

Brain fog from long COVID, chronic fatigue, and other illnesses is tied to less oxygen getting to your brain. The tiny blood vessels narrow. Blood flow slows down. Your brain cells don’t get what they need to work clearly.

BrainO₂ goes right after this problem. First, it gets your brain to open up blood flow. Then, it fills those open pathways with oxygen. This isn’t just “more oxygen” — it’s oxygen sent to the parts of your brain that need it most.

Hyperbaric chambers work. We won’t say otherwise. Breathing oxygen under pressure gives real benefits, and there’s research behind it.

The difference is how the oxygen gets to your brain. With a chamber, you lie still and breathe. The oxygen just shows up. Your blood flow doesn’t increase first — your body takes in what it can.

BrainO₂ works differently. First, the low-oxygen phase tells your brain to send more blood and open up blood vessels. Then, the high-oxygen phase fills those open pathways with oxygen. Exercise makes both steps even stronger — sending 3–5 times more blood to your brain than resting.

Cost matters too. A chamber costs $150–$200 per visit. A full round of 40 sessions = $6,000–$8,000 — and when it’s done, it’s done. BrainO₂ is a one-time purchase you can use every day at home.

Yes. BrainO₂ is gentle. There is no pressure chamber. No risk from too much oxygen at these levels. You don’t need to exercise hard.

Thousands of people with head injuries and concussions have used this system. You start at whatever level you can handle — even a slow walk or easy bike ride is enough to get it working.

If you’re seeing a doctor for your brain injury, let them know you’re using this. Not because it’s risky — just so your care team knows your full plan.

No. This is one of the most common questions we hear — especially from people with long COVID or chronic fatigue.

Very light movement is enough. A bike on the easiest setting. A slow walk on a treadmill. Even seated movement works. The breathing mask does the work — not the exercise.

Many tired people say they feel better during the session than before they started. The high-oxygen phase gives your body a boost while you breathe. Sessions are 25 minutes. Most people feel more energy after, not less.

If you’re very low on energy: start with 10–15 minutes and build up. The system works with wherever you are.

It depends on your situation — and we’d rather be honest than make promises we can’t keep.

People with brain fog often notice the earliest changes. Some feel clearer thinking within the first few sessions — less heaviness, better focus, the ability to hold a thought longer. Some say it feels like “a window opening.”

For head injury recovery: real change usually builds over 4–8 weeks of regular use. Recovery isn’t a straight line. Some weeks are better than others. Each session builds on the last.

If you’re trying to keep your brain sharp as you age: you may not feel a big shift right away because you’re working on a slow problem before it gets bad. Your fitness levels will improve — and that’s the number most tied to long-term brain health.

The most important thing is doing it regularly. 3–5 sessions per week makes a difference. Once every two weeks does not.

Hyperbaric oxygen therapy for cognitive conditions is rarely covered by insurance — not because it doesn’t work, but because it doesn’t fit neatly into a reimbursable diagnostic category. Most insurers simply don’t have a billing code for “improve brain oxygenation.”

LiveO2 isn’t a medical device and doesn’t require a prescription. That’s not a limitation — it’s what makes it accessible. You don’t need a referral, prior authorization, or clinic visit. It’s a one-time purchase you own and use at home on your own schedule.

For many people, that actually makes it more affordable than insurance-covered alternatives. A full course of HBOT (40 sessions) runs $6,000–$8,000 out of pocket even when partially covered. LiveO2 is a one-time investment with unlimited use for life.

Most people notice two different feelings — and once you feel them, you understand how it works.

During the low-oxygen part, you might notice your breathing a bit more. Some people feel a slight heaviness in their chest. It passes quickly. This is your brain opening up blood flow.

During the high-oxygen part, that feeling goes away. Most people feel lighter, clearer, or more relaxed. Some say it’s like stepping outside into fresh air.

When the 25 minutes are done, most people feel awake and alert — not tired. The boost often lasts for hours after.

Each session can feel a little different. The first few may be subtle. By weeks 3–4, most people say the difference is clear.
