Oxygen therapy is used in people who suffer from COPD (such as chronic bronchitis and emphysema), lung cancer, insufficient heart function (heart failure), cystic fibrosis, asthma and occupational diseases that affect the lungs, among others. Oxygen therapy can also be used for specific forms of headache complaints (cluster headache).

Several successful applications of oxygen therapy

Wound care 

Covid-19 virus

Long Covid recovery

type 2 diabetes

Pain relief

Skin problems

Top sport

Restore immune system

(chronic fatigue,

Burn-out ME and Fibromyalgia)

Cosmetic treatments

Cluster headache

Erectile dysfunction

Besides BioCheck, there are currently no programs in the Netherlands in which both the diagnostic equipment and the method have been scientifically validated. This method has especially proven itself in the field of chronic fatigue, such as Burn-out ME, Long Covid and Fibromyalgia. And we are proud of that. We hope that our system can also contribute to your vitality.

The hydrogen oxygen machine (The trademark  Freeair™  has been authorized by Europe representative of Angelbiss) can continuously produce high concentrations of hydrogen from water, using a process called electrolysis. It can be used for hydrogen therapy and health care. The body absorbs hydrogen mainly to fight toxic free radicals and inflammation. Studies have shown that inhaling hydrogen can increase energy, slows down the ageing process and improves muscle recovery after exercise. At the same time, it is a good adjunct to the treatment of more than 60 diseases such as tumors and chronic diseases. HG-900 series hydrogen machines use SPE electrolysis technology, which is non-corrosive, produces no impurity gases and is energy-saving and environmentally friendly.
