Understanding Magnesium in Bottled Water
Magnesium is an essential mineral that plays a vital role in over 300 biochemical reactions in the body, including muscle and nerve function, blood pressure regulation, and energy metabolism. While a balanced diet is the primary source of this nutrient, some bottled waters, particularly natural mineral waters, can provide a substantial supplementary intake.
The mineral content of bottled water varies dramatically depending on its source. Water from natural springs passes through layers of rock, picking up minerals along the way. Brands from volcanic regions, such as Germany's Volcanic Eifel, are often celebrated for their high mineral density. To identify magnesium-rich waters, always check the nutritional label, where the mineral content is required to be listed.
Top Bottled Water Brands High in Magnesium
When searching for what bottled water is high in magnesium, several key brands consistently stand out due to their high mineral concentration. These are often European mineral waters known for their unique compositions.
- Donat Mg: Hailing from Slovenia, Donat Mg is renowned for its extremely high magnesium content, offering up to 1000 mg/L. This water is also known for its strong laxative properties due to its magnesium sulfate composition, so it should be consumed carefully.
- Gerolsteiner: A naturally sparkling mineral water from Germany, Gerolsteiner is another excellent source of magnesium, providing about 108 mg/L. It is also rich in calcium and bicarbonate, contributing to a balanced mineral profile.
- Contrex: This French natural mineral water is a great source of both magnesium and calcium, with a reported magnesium content of around 74.5 mg/L.

Health Benefits of Magnesium-Rich Water
Increasing your magnesium intake through mineral water offers several potential health benefits, especially for those with low dietary magnesium levels. Some of these benefits include:
- Improved Digestion: Waters rich in magnesium sulfate, like Donat Mg, have a laxative effect that can aid in treating occasional constipation.
- Better Bone Health: Magnesium plays a key role in bone mineralization. When combined with other minerals like calcium, magnesium-rich water can support strong and healthy bones.
- Cardiovascular Support: Studies have shown that adequate magnesium intake can help regulate blood pressure and contribute to overall heart health.
- Muscle Relaxation: For athletes or those experiencing muscle cramps, the magnesium in mineral water can assist with muscle function and relaxation.
- Reduced Fatigue: Magnesium deficiency can contribute to tiredness and fatigue. Drinking water with a healthy magnesium content can help maintain energy levels.

Potential Considerations and Risks
While drinking high-magnesium water can be beneficial, it's important to be mindful of certain factors. For instance, consuming excessive amounts of magnesium can lead to digestive discomfort, such as diarrhea. If you have pre-existing kidney problems, it is crucial to consult a healthcare professional before significantly increasing your mineral water intake, as your kidneys may have difficulty filtering out high levels of minerals. For daily hydration, it is recommended to alternate between mineral water and lower-mineralized waters to avoid potential digestive issues. Always pay attention to how your body reacts and adjust your consumption accordingly.
Conclusion
For those seeking to increase their magnesium intake, choosing a bottled water high in magnesium is an excellent and natural approach. Brands such as Donat Mg, Gerolsteiner, and Contrex offer reliably high levels of this essential mineral, providing numerous health benefits from improved digestion to better bone and heart health. However, as with any dietary change, it's important to understand the varying mineral levels and listen to your body to avoid overconsumption. By comparing brands and checking labels, you can easily find the right magnesium-rich bottled water to support your health and hydration goals.
