According to the Food and Drug Administration (FDA), for water to be classified as 'mineral water,' it must contain at least 250 parts per million of total dissolved solids, including naturally occurring minerals. So, what happens when you drink mineral water every day?

Quick Summary

Daily consumption of mineral water can enrich your diet with essential minerals like calcium and magnesium, supporting bone and heart health and aiding digestion. It's generally safe but requires moderation, as excessive intake can lead to mineral imbalances or impact those with specific health conditions. Potential drawbacks also include the environmental concerns and microplastic exposure from plastic bottles.

Key Points

Rich Mineral Source: Daily mineral water provides a consistent intake of bioavailable minerals like calcium and magnesium, which are easily absorbed by the body.
Supports Strong Bones: The high calcium content in mineral water can improve bone density, especially beneficial for women after menopause.
Benefits Heart Health: Regular consumption may help lower blood pressure and improve cholesterol levels, supporting cardiovascular function.
Enhances Digestion: Magnesium-rich mineral water can aid digestion and relieve constipation by attracting water to the intestines.
Helps Maintain Electrolyte Balance: It's a natural way to replenish electrolytes lost during exercise, aiding in effective rehydration.
Potential for Excessive Intake: Overconsumption can lead to mineral imbalances or exacerbate conditions like hypertension due to high sodium levels in some brands.
Consider the Container: Bottled mineral water poses environmental and health risks from plastics like BPA and microplastics.

The Health Benefits of Daily Mineral Water Consumption

Daily intake of mineral water can provide a consistent and bioavailable source of essential minerals, which are easily absorbed by the body due to their ionic form. Unlike tap water, which undergoes chemical disinfection, natural mineral water is bottled at the source and remains largely unprocessed, preserving its natural mineral composition. The specific mineral content varies significantly by brand and source, but common minerals include calcium, magnesium, and sodium, each offering unique health advantages.

Supporting Bone Health

Calcium is crucial for developing and maintaining strong bones throughout all stages of life. Studies have shown that the body can absorb calcium from mineral water just as effectively, if not more so, than from dairy products. For example, a study involving postmenopausal women found that regular consumption of calcium-rich mineral water was associated with significantly higher bone mass density. Magnesium and bicarbonate found in mineral water also contribute to robust bones.

Enhancing Cardiovascular Health

Research suggests that drinking mineral water may benefit cardiovascular health, particularly through its magnesium and calcium content. A 2004 study found that subjects with borderline hypertension and low calcium/magnesium levels who drank one liter of mineral water daily experienced a significant decrease in blood pressure. Another study noted that regular carbonated mineral water intake could reduce 'bad' (LDL) cholesterol and increase 'good' (HDL) cholesterol in postmenopausal women.

Aiding Digestive Function

For those who suffer from digestive issues, mineral water can be a natural remedy. The magnesium and sulfate content can draw water into the intestines, softening stools and promoting regular bowel movements. Carbonated mineral water, in particular, has been shown to improve symptoms of constipation and indigestion. However, individuals with gastroesophageal reflux disease (GERD) may find that carbonation exacerbates their symptoms.

The Importance of Electrolyte Balance

Mineral water is an excellent source of electrolytes, such as sodium, potassium, calcium, and magnesium, which are vital for maintaining fluid balance and nerve and muscle function. This is especially beneficial for athletes or those living in hot climates, as it helps replenish electrolytes lost through sweat. Unlike plain water, mineral water's electrolyte composition provides more comprehensive rehydration.

Navigating Potential Drawbacks

While largely beneficial, daily consumption of mineral water requires awareness of potential downsides. The mineral content, especially sodium, varies by brand. Individuals on a low-sodium diet due to high blood pressure or heart conditions should check the label carefully. The primary concern for most people relates to environmental factors and the packaging. Most bottled mineral water is sold in plastic, which contributes to waste and can expose the consumer to microplastics or harmful chemicals like BPA. For those who prefer a consistent mineral profile, a home water purification system with added minerals might be a more sustainable option.

Comparison Table: Mineral Water vs. Tap Water


Feature	Mineral Water	Tap Water
Mineral Content	Sourced from underground springs with naturally occurring, higher mineral content; composition varies by source.	Mineral content varies by region, but quantities are generally lower than mineral water; minerals may be added.
Processing	Bottled directly at the source; can be naturally carbonated or have CO2 added/removed.	Sourced from municipal supplies, rivers, or lakes; undergoes extensive chemical disinfection and filtration.
Taste	Flavor profile is influenced by its unique mineral composition; can range from salty to sweet.	Taste is more uniform but can be affected by chlorine or local pipe infrastructure.
Cost	Significantly more expensive due to sourcing, bottling, and transportation costs.	Highly affordable and easily accessible.
Environmental Impact	High impact due to single-use plastic bottles, requiring recycling and transport.	Very low environmental impact; delivered via existing infrastructure.
Health Control	Mineral content is controlled and labeled; risks of plastic contamination exist.	Heavily regulated for safety by EPA standards; potential for contaminants from old pipes.

Conclusion: A Balanced Perspective on Mineral Water

Drinking mineral water every day can be a healthful practice, offering a flavorful way to increase your intake of essential minerals like calcium and magnesium. These minerals have been linked to improved bone density, better heart health, and enhanced digestive function. However, moderation is key, especially for those with mineral sensitivities or sodium restrictions, as the exact composition varies. The environmental and health concerns associated with plastic bottling must also be considered. For many, a balanced diet is the most effective way to obtain a full spectrum of minerals. Ultimately, incorporating mineral water into a healthy lifestyle is a beneficial choice, but one should remain mindful of both the source and the quantity consumed.

Potential Complications of Excessive Intake

Excessive Mineral Intake: Overconsumption can lead to mineral imbalances, particularly of magnesium and calcium, which may cause complications like kidney stones or digestive discomfort.
High Sodium Levels: Some mineral water contains elevated sodium, posing a risk to those with hypertension or other conditions requiring a low-sodium diet.
Digestive Issues: Carbonated mineral water can cause bloating, gas, or acid reflux symptoms in sensitive individuals.
Kidney Strain: The kidneys must filter excess minerals from the blood, and excessive intake can put additional stress on them over time, which is especially concerning for individuals with pre-existing kidney conditions.
Tooth Enamel Erosion: Sparkling mineral water is more acidic than still water, and regular, high intake could contribute to enamel erosion over time, though it is far less damaging than sugary soft drinks.

Final Thoughts

Mineral water is a viable source of supplementary minerals, but it is not a substitute for a balanced diet rich in whole foods. It is a safe and beneficial hydration choice when consumed thoughtfully, with an eye towards specific mineral content and the potential health or environmental implications of its packaging. Listen to your body and consult a healthcare provider with any specific health concerns.
