The unique geological configuration around Rogaška helps create the world's most magnesium-rich mineral water. Scientific research was conducted into the age of Rogaška ROI water, which was estimated to be some 8,000 years old. ROI springs in the middle of most tectonically diverse areas in the world, featuring three regional faults ALPS, DINARIC ALPS, PANNONIAN BASIN. The oldest rock layer - probably about 285 million years old - is located near Rogaška Slatina. Every drop of ROI mineral water took thousands of years to come into being. This is the time the water needs to travel through the layers of rock that enrich it with minerals. The ROI natural mineral water rises to the surface of the earth through the shafts without the aid of pumps, as it is driven by the carbon dioxide present within it. In the archives of the parish church of St. Cross in Rogaska some interesting details were preserved. Among other things it says that a lot of the local people lived for a hundred years. The reason was to be regular drinking of mineral water ROI

A water’s TDS is normally made up mainly of carbonates, bicarbonates, chlorides, sulphates, phosphates, nitrates, calcium, magnesium, sodium, potassium, iron, manganese, and a few other minerals. Gases, colloids, or sediment is not included in the TDS measurement. After mouth feel, TDS is the second most important factor in matching water with food. The higher the mineral content, the more distinct a water’s taste can be.
Magnesium is responsible for more than 300 processes in the human body and is an essential mineral nutrient for life. Magnesium plays a major role in biological functions within the body particularly in disease prevention and maintaining overall health.
  • Drinking ROI has proven to have beneficial effects on the organism.
  • The effects of the ROI natural mineral water depend on the mode of use.
  • ROI is recommended in cases of increased need for magnesium: sporting activities, periods of intensive growth, pregnancy and breast-feeding.
  • ROI is marked by high magnesium content and a low presence of salt.
  • Premium is of higher quality, i.e we only sell natural single sourced bottled water from the ROI springs in the middle of Slovenia.
  • Luxury is timeless. Storied. Scarcity. Social cachet.
Excessive quantities of ROI can have a laxative effect. Adapt the daily dose accordingly.
Yes, it’s usually 24 months from the field process.
  • ROI is unlike any other mineral water in the world. As the most magnesium-rich water there is, it offers various benefits, but only when enjoyed in moderation. Learn the correct ways to drink ROI depending on the circumstances on our ‘How To Drink’ page.
  • The unique ROI mineral water has various health effects, depending on the way it is drunk. Drink ROI fast and warm to accelerate bowel activity. Drink ROI slow and cool to increase mineral re-absorption.
  • HEART: Magnesium has beneficial effects on cardiac arrhythmia conditions.
  • MUSCLES: Magnesium is important for the good condition of the muscles and prevents muscle cramps (Magnesium transmitting oxygen to the tissues)
  • DIGESTION: The carbon dioxide in the natural mineral water ROI stimulates digestion and the blood supply of the mucous membranes.
  • OVEREATING or DRINKING: ROI alleviates problems created from overeating, strong coffee or drinking large quantities of alcoholic beverages.
  • INSULIN: The hydrogen carbonates present in ROI stimulate the activity of insulin.
  • GLUCOSE: The hydrogen carbonates present in ROI improve the level of glucose in the blood.
  • ROI helps reduce or even eliminate a hangover as it ensures rehydration and replenishes the minerals excreted by the kidneys during drinking. Minerals maintain the pH balance in the body to revitalize the system and help to alleviate an upset stomach. (Take our stomach juice acid)
The ROI mineral water is one of the most mineralised water on the world. Beside Magnesium, there are other element the effect to human body.
  • Very import is element is Silica (SiO2) which is very often used in “beauty industry”.
  • Silica can hinder the effects of coronary disease by fortifying blood vessels
  • Silica assists in the prevention of kidney stones and heal infection of the urinary tract. It is a natural diuretic, which can encourage excretion by 30%
  • By taking part in the synthesis of elastin and collagen, Silica regenerates skin and the vascular walls
  • Silica in ROI aids in the repair and maintenance of vital lung tissues and defending them from pollution
  • Silica may normalize circulation and regulate high blood pressure
  • Silica improves mobility by improving the elasticity of the joints
  • Silica beautifies hair with lustre, elasticity and vigour
  • Silica delays the aging process
  • Silica may hinder the pain of osteoarthritis and rheumatism
