What does hydrogen do in the body?
Hydrogen therapy is the inhalation of molecular hydrogen (H₂) gas — the smallest molecule there is — delivered through a light nasal cannula while you sit and relax. Hydrogen is studied for its role in supporting healthy energy production and everyday cellular renewal, and is associated with the NRF2 pathway, part of the body's own built-in antioxidant response. Unlike broad antioxidants, hydrogen is thought to act selectively, which is one reason it has been the subject of ongoing research since a landmark study in 2007.
At Green Circle Wellness we use Hydro Heal medical-grade molecular hydrogen machines. A session is quiet and comfortable: you breathe normally, there are no needles and no downtime, and you can return to your day straight afterwards. Hydrogen therapy is offered as a complement to your wider care plan — many patients pair it with IV therapy, ozone therapy or a functional medicine programme.
We offer hydrogen therapy in person at our clinic in Chicago's West Loop, delivered by our clinical team. It's for adults looking to support energy, recovery and healthy ageing alongside their other care.
Hydrogen has been studied for its effects on the body since a landmark study in 2007. Here's what you need to know about how we use it today:
A Selective Antioxidant
Molecular hydrogen (H₂) is the smallest molecule there is, so it moves easily through the body's tissues and cells. Research associates it with the NRF2 pathway — the body's own built-in antioxidant response — and suggests it acts selectively rather than broadly. It is studied for its role in supporting:
Healthy energy production
Everyday cellular renewal
Recovery after exertion
The body's own antioxidant defences
Side Effects
Hydrogen inhalation is generally well tolerated. Hydrogen is a naturally occurring molecule, and at the concentrations used in therapy sessions it is non-toxic and non-irritating. Some people notice mild light-headedness or relaxation during a session, which passes quickly. Tell your provider if you feel unwell at any point.
How It's Delivered
Hydrogen therapy is an in-clinic treatment. At Green Circle Wellness we use Hydro Heal medical-grade molecular hydrogen machines. A light nasal cannula is fitted, you sit comfortably and breathe normally for the length of your session. There are no needles, no sedation and no downtime — you can return to your day straight afterwards. Sessions can be booked on their own or added to an IV infusion or ozone visit.
Warnings and Contraindications
Hydrogen therapy is offered as a complement to your care, not a replacement for medical treatment. Please let us know before your session if you:
Are pregnant or breastfeeding
Have a respiratory condition or use supplemental oxygen
Are currently unwell or recovering from surgery
If you have an existing medical condition, a New Patient Consultation — available in person or by video or phone — helps confirm it's suitable for you.
Do I need a consultation first
Not necessarily. Sessions can be booked on their own; if you have an existing medical condition, a New Patient Consultation — in person or by video or phone — helps confirm it's suitable for you.
Can I combine it with other treatments?
Yes. Hydrogen therapy is often paired with IV vitamin therapy, ozone therapy or a functional medicine plan in the same visit.
What does a session feel like?
Relaxing. You sit comfortably and breathe normally through a light nasal cannula. There are no needles, no sedation and no downtime.
