Donat is a natural mineral water from the springs of Rogaška Slatina in Slovenia. It has a high content of magnesium. It helps with constipation problems, heartburn and magnesium deficiency problems.
History
Donat was first commercially available in 1908, but the history of Rogaška Slatina springs is much older. Excavation in the area confirmed Celtic and Roman settlements, indicating that the spring was already in use in ancient times.[1][2]
The first owner of the springs was the parish of the nearby village Sveti Križ, and the first written records about the springs date back to 1141, when the mineral water spring was cited in a document as a boundary point in a property transaction. The first known analysis of the water was carried out in 1572.[3]
