The quality of drinking water is a crucial determinant of human health, and certain types of water, such as artesian water, offer more than just hydration. Artesian water is naturally filtered and pressurised within confined aquifers, resulting in a mineral-rich and contaminant-free water source. New Zealand’s artesian water is particularly notable for its high silica content, a mineral that plays a vital role in various physiological processes. This article delves deeper into the health benefits of silica, exploring its specific functions and the advantages of consuming silica-rich artesian water from New Zealand.
The unique geological conditions of New Zealand contribute to the high silica content of its artesian water. The country’s active volcanic regions and extensive tectonic activity have created aquifers that are rich in silica and other beneficial minerals.
- Silica (SiO₂) Content: The concentration of silica in New Zealand artesian water can exceed 30 mg/L, which is significantly higher than the levels found in most other bottled waters. This high silica content is primarily due to the water's prolonged contact with volcanic rock formations, which leach silica into the water during its natural filtration process.
- Purity: The natural filtration process through volcanic rock and other geological layers ensures that New Zealand’s artesian water is exceptionally pure, with minimal levels of contaminants. This purity, combined with high silica content, makes it a particularly beneficial source of drinking water.
The mineral composition of New Zealand artesian water, particularly its high silica content, sets it apart from other mineral waters. The following comparisons highlight the differences:
The mineral composition of New Zealand artesian water, particularly its high silica content, sets it apart from other mineral waters. The following comparisons highlight the differences:
1. RAIR Artesian Water
Silica Content: >30 mg/L
Other Minerals: Typically high in sodium and moderately rich in calcium and magnesium.
Health Benefits:
- Promotes bone health by enhancing collagen synthesis and calcium absorption. - Supports skin elasticity, hydration, and reduces wrinkles due to its role in collagen production. - Contributes to cardiovascular health by maintaining vascular elasticity and preventing arterial calcification. - Protects neurological health by aiding in aluminum detoxification and preserving cognitive function. - Enhances hair and nail strength through keratin synthesis. - Supports joint health by contributing to cartilage formation and joint lubrication.
2. Fiji Water (Viti Levu, Fiji)
Silica Content: ~25 mg/L
Other Minerals: Includes calcium, magnesium, and bicarbonates.
Health Benefits:
- Similar to New Zealand artesian water, Fiji Water's high silica content supports skin health, hair and nail strength, and joint flexibility. - Slightly lower silica levels than New Zealand's water, but still beneficial for bone density and cognitive protection. - Known for its soft taste, which is attributed to the balanced mineral content. - Comparable neurological benefits due to its moderate silica content, though less potent in cardiovascular health compared to New Zealand's offering.
3. Evian (French Alps, France)
Silica Content: ~15 mg/L
Other Minerals: Rich in calcium (80 mg/L), magnesium, bicarbonates, and low in sodium.
Health Benefits:
- Calcium-rich, making it beneficial for bone health, though the lower silica content means it provides less support for collagen production and skin elasticity. - Promotes hydration and electrolyte balance, making it a good option for maintaining overall health. - Less effective in promoting joint and neurological health due to the lower silica concentration. - Known for its balanced mineral profile, which supports general well-being.
4. Gerolsteiner (Eifel, Germany)
Silica Content: ~10 mg/L
Other Minerals: Exceptionally high in calcium (348 mg/L) and magnesium (108 mg/L), with significant bicarbonate levels.
Health Benefits:
- Highly beneficial for bone health due to the high calcium and magnesium content, though the silica content is too low to offer the specific collagen and skin health benefits seen in New Zealand’s artesian water. - Promotes digestive health through its bicarbonate content, which helps neutralise stomach acid. - The low silica content limits its effectiveness in supporting neurological health and cognitive function. - Beneficial for preventing osteoporosis, but less effective in skin, hair, and joint health compared to higher silica waters.
5. San Pellegrino (Italian Alps, Italy)
Silica Content: ~7 mg/L
Other Minerals: High in calcium, magnesium, bicarbonates, and rich in sulfate.
Health Benefits:
- Primarily supports digestive health due to its high bicarbonate and sulfate content, which aid in digestion and can relieve symptoms of indigestion. - The low silica content means it offers limited benefits for skin, hair, and nail health, and does not significantly contribute to joint or neurological health. - The high mineral content is beneficial for maintaining bone health, though the focus is more on digestive and general health benefits rather than specific anti-aging or cognitive support.
6. VOSS (Norway)
Silica Content: ~5 mg/L
Other Minerals: Low in total dissolved solids (TDS), with minimal mineral content overall.
Health Benefits:
- Known for its purity and neutral taste, VOSS is often chosen for its clean, crisp flavor rather than its mineral content. - The low mineral content means it offers fewer health benefits in terms of bone, skin, or joint health compared to silica-rich waters like those from New Zealand. - Ideal for individuals looking for a pure, low-mineral water option, though it lacks the health-promoting properties of more mineral-rich waters.
7. Acqua Panna (Tuscany, Italy)
Silica Content: ~6 mg/L
Other Minerals: Contains calcium, magnesium, bicarbonates, and sulfates.
Health Benefits:
- Known for its smooth taste, Acqua Panna offers moderate health benefits, particularly for digestive health, due to its bicarbonate content. - The low silica content limits its effectiveness in promoting skin elasticity, bone strength, and neurological health. - Provides general hydration and supports overall well-being, but does not offer the specific anti-aging or cognitive benefits associated with high-silica waters like those from New Zealand.
New Zealand artesian water, with its exceptionally high silica content, offers unique and potent health benefits that set it apart from other mineral waters worldwide. While other waters like Fiji and Evian provide some level of silica, they do not match the concentrations found in New Zealand’s artesian sources. This makes New Zealand artesian water particularly effective in promoting bone health, skin elasticity, cardiovascular protection, neurological health, and hair and nail strength. In comparison, waters like Gerolsteiner and San Pellegrino, although rich in other beneficial minerals, lack the silica concentration necessary to provide the same comprehensive health benefits, particularly in the areas of anti-aging, cognitive protection, and joint health.
For consumers seeking a water source that offers both purity and a high concentration of health-promoting silica, New Zealand artesian water stands out as a superior choice.
