Note-Made in Hungary. Batch Expiration is printed in European format which is day/month/year. Examples of what it looks like: 30/06/2021 would be June 30th 2021. If a bottle expiration looks like 08/09/21, it would be September 8th 2021. KAQUN water, unique in its nature, was born as a result of research work of twenty years. This drinking water made with a special procedure originates from Hungary. The first device able to bind the active oxygen in pure water was made in 1981. After that twenty years of research work and development followed when the high oxygen content KAQUN water could come into the consumer market. The KAQUN bath water is produced with the same technology after the special treatment, filtering of the local pipeline water. In Hungary the first KAQUN Club opened in 2002 in Dobogókő, whose aim is to improve the general physical condition. Since then in Hungary KAQUN bath clubs were built in several places (in Miskolc, Veszprém, Hévíz, Kerepes), in two locations in Budapest, and now in Las Vegas. KAQUN water has undergone 10+ years of clinical and laboratory research carried out on both healthy volunteers and those with health challenges, as well as animal studies. Oxygen deficiency is a direct precursor to nearly all illnesses and disease. Without this vital element, human life ends in approximately 6 minutes. Oxygen is essential to wellness. Human bodies are not getting anywhere near the required levels of oxygen needed for peak health, vitality, immunity and longevity. Until now, the delivery of highly absorbable and usable oxygen has been limited by the exchange of CO2 with Oxygen at the level of the blood, and the degree to which the lungs can accept high concentrations while breathing highly concentrated Oxygen. Kaqun is different. Kaqun water penetrates the skin directly, permeating the interstitial fluids and connective tissue and thereby delivering higher levels of oxygen than have been possible before. Kaqun water is created by a specific treatment process that enables substantially increased absorption effects in the body. As a result of KAQUN technology, oxygen has been made into a stabilized form with concentrations of 18-25 mg per liter. There are no chemicals or toxic materials used in the production of KAQUN, and the oxygen is derived from the water itself; not from an outside source. There are two forms KAQUN water is delivered to the body: through the skin (KAQUN baths) and by drinking a more mild form of the KAQUN water (KAQUN drinking water). The drinking water of KAQUN penetrates the mucous membranes of the stomach and gastrointestinal tract, and then through its absorption qualities penetrates the tissues.
