Created by the Greek mythological winged horse Pegasus. Legend has it that Pegasus, instructed by Apollo, struck his hoof to the earth at Rogaška and opened up the Roitschocrene spring.

What sprung forth was the world’s most magnesium-rich mineral water.

At that solemn moment, Apollo said the now famous words:

Hereby lies the source of health and the true power of the gods. Instead of Hippocrene, drink Roitschocrene from the spring in front of you.

ROI springs in the middle of Slovenia’s most tectonically diverse areas, featuring three regional faults. This unique geological and hydrogeological configuration is the invaluable source of two natural resources, springing from depths of approx. 300 meters. Dissolving through rocks rich in magnesium, calcium, sulfates, bicarbonates and assisted by natural gas, here springs the thermal water used for centuries at the Rogaška Health Spa, and the ROI mineral water, which is particularly rich in magnesium and other beneficial minerals.

Magnesium plays a major role in biological functions within the body particularly in disease  prevention and maintaining overall health. Several excellent reviews have been written on  the role of Magnesium in health in disease and we recommend any interested reader to  consult (Laires, Monteiro, and Bicho 2004) and (Musso 2009) for a general introduction to  the topic. In brief, the academic literature broadly agrees on several clinical situations  related to magnesium including: renal disease, hypertension, pre-eclampsia, diabetes  mellitus, cardiac disease, and the administration of therapeutic drugs (Sanders, Huijgen HJ,  and Sanders R 1999), though some specialists also include alcoholism, osteoporosis (Fatemi  et al. 1991) atherosclerosis and asthma (Saris et al. 2000).

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.

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. 

Warning: Excessive quantities of ROI can have a laxative effect. Adapt the daily dose accordingly.
