Not all water is created equal. Mineral water, rich in essential minerals like calcium, magnesium, and potassium, offers health benefits beyond basic hydration. In this article, we explore the science behind mineral water and how these naturally occurring minerals can contribute to your overall health and wellbeing.
What Is Mineral Water?
Mineral water comes from naturally occurring springs and contains a variety of minerals and trace elements that originate from the rocks and soil the water passes through. To be classified as "mineral water" in the UK and EU, the water must:
- Come from a specific underground water source
- Be bottled at the source
- Contain a consistent level of minerals and trace elements
- Be free from any treatments that would alter its mineral composition (although some processes like filtering out particles are permitted)
The specific mineral content varies depending on the geological characteristics of the source, resulting in different types of mineral water with varying health benefits.
Key Minerals in Water and Their Benefits
Mineral water can contain a wide range of minerals, each with specific health benefits:
Essential Minerals and Their Health Effects
Calcium
Amount in typical mineral water: 10-250 mg/L
Benefits:
- Strengthens bones and teeth
- Supports muscle function
- Aids in blood clotting
- Helps regulate heartbeat
Studies suggest that calcium from mineral water is well absorbed by the body, sometimes even better than calcium from dietary sources.
Magnesium
Amount in typical mineral water: 5-120 mg/L
Benefits:
- Supports over 300 enzyme reactions in the body
- Maintains normal muscle and nerve function
- Regulates heart rhythm
- Contributes to bone health
- Helps reduce stress and anxiety
Magnesium deficiency is relatively common, and mineral water can be a good supplementary source.
Potassium
Amount in typical mineral water: 1-12 mg/L
Benefits:
- Helps maintain fluid balance
- Supports nerve function
- Regulates muscle contractions, including the heart
- May help lower blood pressure
Bicarbonate
Amount in typical mineral water: 50-2000 mg/L
Benefits:
- Helps neutralize acid in the body
- Can aid digestion and reduce acid reflux
- May help prevent kidney stones
Silica
Amount in typical mineral water: 5-40 mg/L
Benefits:
- Contributes to bone and connective tissue health
- Promotes skin, hair, and nail health
- May help protect against aluminum accumulation in the brain
Sulfate
Amount in typical mineral water: 5-500 mg/L
Benefits:
- Supports digestive health
- Mild laxative effect at higher concentrations
- Helps the body absorb and use certain nutrients
"Minerals in water can contribute significantly to daily mineral intake, particularly for elements like calcium and magnesium."— Journal of Nutrition Research
Scientific Research on Mineral Water Benefits
A growing body of scientific research supports various health benefits of mineral water consumption:
Cardiovascular Health
Several studies have found connections between mineral water consumption and heart health:
- A study published in the Journal of Clinical Nutrition found that drinking mineral water rich in magnesium and bicarbonate can help lower LDL (bad) cholesterol levels.
- Research suggests that regular consumption of mineral water containing calcium and magnesium may help lower blood pressure in some individuals.
- The combined effect of minerals like potassium, calcium, and magnesium can support overall cardiovascular function.
Bone Health
Mineral water can contribute to maintaining strong, healthy bones:
- Studies indicate that the calcium in mineral water is highly bioavailable, meaning it's easily absorbed by the body.
- Research from the American Journal of Clinical Nutrition found that women who regularly consumed calcium-rich mineral water had better bone mineral density.
- The combination of calcium, magnesium, and silica in some mineral waters provides comprehensive support for bone health.
Digestive Benefits
Various types of mineral water can support digestive health:
- Mineral waters rich in bicarbonate can help neutralize stomach acid and may provide relief from acid reflux and indigestion.
- Waters containing sulfate can have a mild laxative effect, potentially aiding those with constipation.
- Some research suggests mineral water may help improve gallbladder function and reduce risk of gallstones.
Types of Mineral Water in the UK
The UK has several sources of mineral water, each with its unique mineral profile:
| Source/Brand | Region | Notable Minerals | Characteristics |
|---|---|---|---|
| Highland Spring | Perthshire, Scotland | Low mineralization, balanced calcium and magnesium | Soft, clean taste |
| Buxton | Derbyshire, England | Calcium, magnesium, potassium | Crisp, refreshing taste |
| Harrogate Spring | Yorkshire, England | Balanced mineralization | Smooth taste with slight sweetness |
| Malvern | Worcestershire, England | Very low mineralization | Pure, clean taste |
| Ty Nant | Wales | Low sodium, balanced minerals | Soft, slightly sweet taste |
How to Choose the Right Mineral Water
With so many options available, choosing the right mineral water can seem overwhelming. Here are some factors to consider:
Selection Criteria for Mineral Water
- Total Dissolved Solids (TDS): This measures the total mineral content.
- Low mineralization (less than 500 mg/L): Light, refreshing taste
- Medium mineralization (500-1500 mg/L): More pronounced mineral taste
- High mineralization (over 1500 mg/L): Strong mineral flavor, more therapeutic properties
- Specific Health Needs:
- For bone health: Choose waters high in calcium, magnesium, and silica
- For digestive issues: Look for waters with bicarbonate and sulfate
- For heart health: Waters with magnesium, calcium, and potassium may be beneficial
- For low-sodium diets: Check the sodium content (should be under 20 mg/L)
- Source and Purity: Look for waters from protected, unpolluted sources with consistent mineral content.
- Taste Preference: Mineral content significantly affects taste. Try different waters to find what you enjoy.
- Carbonation: Both still and sparkling mineral waters offer the same mineral benefits; the choice is personal preference.
Mineral Water vs. Other Water Types
How does mineral water compare to other water options?
Mineral Water
- Naturally contains minerals from underground sources
- Bottled at source with minimal treatment
- Consistent mineral profile
- Generally more expensive
- May have environmental impact from bottling and transport
Tap Water
- Mineral content varies by location
- Treated to ensure safety, may include chlorine
- More environmentally friendly option
- Very affordable
- Quality and taste can vary
Filtered Water
- Tap water that's been filtered to remove contaminants
- Most filters also remove some beneficial minerals
- Improved taste compared to tap water
- Cost-effective middle ground
- Quality depends on filter type and maintenance
Distilled Water
- All minerals removed through distillation
- Very pure but lacks nutritional benefits
- Flat taste that many find unpleasant
- Primarily used for medical equipment or appliances
- Not recommended as a primary drinking water
Incorporating Mineral Water into Daily Life
Here are some practical ways to enjoy the benefits of mineral water:
- Regular Consumption: Replace one or two glasses of regular water with mineral water daily to start experiencing the benefits.
- Cooking: Use mineral water in cooking, especially for soups, stews, and rice, to add minerals to your meals.
- Post-Exercise: Mineral water can be particularly beneficial after physical activity to replenish minerals lost through sweat.
- Morning Routine: Start your day with a glass of room-temperature mineral water to help activate your digestive system.
- Flavor Enhancer: Add a splash of fresh lemon or lime to naturally carbonated mineral water for a refreshing, sugar-free beverage.
- Tea and Coffee: Try preparing these beverages with mineral water to enhance flavor and mineral content.
