According to the U.S. Food and Drug Administration, for water to be labeled 'mineral water,' it must contain at least 250 parts per million of total dissolved solids. With this high mineral content, many people ask: is it OK to drink mineral water every day?

Quick Summary

Daily consumption of mineral water offers potential health benefits from its rich mineral content but requires consideration of risks like excessive mineral intake, plastic packaging, and cost.

Key Points

Moderation is Key: Daily mineral water is generally safe but should be consumed in moderation to avoid excessive intake of certain minerals.
Check the Label: Different brands have varying mineral compositions; those with high sodium content should be avoided by individuals with hypertension.
Consider Plastic-Free Options: Many mineral waters are sold in plastic bottles that can leach microplastics and chemicals like BPA; consider glass bottles or filtered tap water instead.
Consult a Doctor for Conditions: Individuals with kidney issues or other medical conditions should consult a healthcare provider before making mineral water a daily habit.
Tap Water is a Viable Alternative: In many regions, tap water is a safe, cost-effective, and more environmentally friendly option, and its mineral content can vary.
Benefits vs. Risks: Weigh the potential bone and heart health benefits against the risks of high mineral levels, plastic exposure, and cost.

The Allure and Benefits of Daily Mineral Water Consumption

Mineral water, sourced from protected underground reservoirs and springs, contains naturally occurring minerals known for their distinctive taste and potential health benefits. These minerals are essential nutrients the body needs. Research highlights several potential health advantages of consuming mineral water daily.

Supporting Bone Health

Mineral water can be a bioavailable source of calcium and magnesium, both crucial for strong bones. Some studies indicate calcium from mineral water is absorbed as effectively as from dairy. Research on postmenopausal women suggests that regular consumption of calcium-rich mineral water may lead to higher bone mass density.

Enhancing Cardiovascular and Digestive Health

Consuming mineral water rich in calcium and magnesium may also benefit heart health by potentially helping to lower blood pressure in those with borderline hypertension. A study observed reduced blood pressure in adults after drinking a liter of natural mineral water daily for four weeks. Additionally, carbonated mineral water is known for aiding digestion, potentially easing constipation and dyspepsia. Magnesium in the water can help draw water into the intestines, supporting regular bowel movements.

Potential Risks and Considerations of Daily Consumption

While there are potential benefits, it's important to consider the possible risks associated with daily mineral water consumption. Moderation is key to balancing the pros and cons.

The Double-Edged Sword of High Mineral Content

For most healthy adults, drinking mineral water daily as part of a balanced diet is safe. However, excessive consumption can be problematic. Some mineral waters have high sodium levels, which can be a concern for individuals with hypertension or those on a low-sodium diet. High sodium can also potentially increase calcium excretion. People with pre-existing kidney conditions should be mindful of the high mineral content, as it may increase the kidneys' workload.

Environmental and Health Concerns of Plastic Bottles

Most mineral water is sold in single-use plastic bottles, raising environmental and health issues. These bottles can contain microplastics and chemicals like BPA, which may leach into the water. Exposure to BPA is linked to potential hormonal disruptions. Choosing glass bottles or filtering tap water can help reduce this risk.

Comparison Table: Mineral Water vs. Tap Water


Feature	Mineral Water	Tap Water
Mineral Content	Varies significantly by brand and source; often high in calcium and magnesium.	Varies by region; can contain some minerals, especially from groundwater, but usually in lower amounts.
Cost	Significantly more expensive due to packaging, sourcing, and transport.	Very low cost, often available for free from the tap.
Environmental Impact	High carbon footprint from packaging and transportation; contributes to plastic pollution.	Very low environmental impact; no single-use packaging involved.
Purity and Regulation	Must come from a protected underground source and retain its original purity.	Subjected to rigorous testing and regulation by municipalities to ensure safety.
Taste	Diverse and nuanced flavors based on mineral composition, often preferred by consumers.	Flavor can be affected by treatment processes like chlorination, varying by location.

Making the Right Choice for Your Health

Deciding whether to drink mineral water daily depends on your individual health needs and priorities. For some, the specific minerals offer benefits. For others, particularly those with dietary restrictions or medical conditions, it might not be the best option. Tap water, often high quality, safe, affordable, and environmentally friendly, is a good alternative in many areas. Filtering tap water can be a practical solution to get clean water while reducing plastic waste. Consult a healthcare professional before making significant changes to your hydration habits, especially if you have underlying health conditions, to determine the best approach for you.

Conclusion: Hydration with Awareness

In conclusion, daily mineral water consumption is generally safe for most people and can provide valuable minerals for bone, heart, and digestive health. However, it should be consumed mindfully, considering potential drawbacks like high sodium in some varieties, the environmental and health risks of plastic bottles, and higher cost. Prioritizing adequate fluid intake is the most important factor in hydration, regardless of the source. By understanding the potential benefits and risks, you can make an informed choice that suits your health and lifestyle. Healthline provides more context on the benefits of mineral water.

Frequently Asked Questions

Mineral water can offer additional health benefits due to its natural mineral content, but tap water is often just as safe, more cost-effective, and environmentally friendly. The 'best' choice depends on your specific health needs and priorities.

Excessive intake can cause digestive upset like bloating or diarrhea, electrolyte imbalances due to high mineral concentrations, and may put a strain on the kidneys. Sparkling varieties can also affect dental enamel.

Some studies suggest that mineral water rich in calcium and magnesium may help lower blood pressure in individuals with borderline hypertension. However, those sensitive to sodium should be cautious and check mineral labels.

Yes, mineral water can be a good source of bioavailable calcium and magnesium, two essential minerals for building and maintaining strong bones.

Yes, the single-use plastic bottles used for mineral water contribute to plastic waste and have a higher carbon footprint from production and transportation compared to tap water. Choosing glass bottles or filtering tap water can mitigate this.

There are no set guidelines, as safe intake varies based on the water's mineral composition and your individual health. Drinking in moderation is advised. Always check the mineral content, particularly sodium, on the label.

Sparkling mineral water is more acidic than still water, and regular, high consumption could potentially contribute to minor tooth enamel erosion over time. Rinsing your mouth with plain water afterward can help.

Yes, studies have detected microplastics in many brands of bottled mineral water, though the long-term health effects are still being researched. Avoiding plastic bottles is the best way to minimize your exposure.
