The Artesian Source of Fiji Water
Fiji Water's unique mineral composition is a direct result of its extraordinary origin. The water is sourced from a protected artesian aquifer deep within the earth in the remote Yaqara Valley on the island of Viti Levu. The water is shielded from external elements by layers of impermeable rock. As rainfall purifies itself on a journey across the Pacific, it is naturally filtered through volcanic rock. This process not only purifies the water but also infuses it with a variety of naturally occurring minerals and electrolytes, including calcium, magnesium, and a notable amount of silica. The natural pressure of the artesian aquifer then forces the water to the surface, where it is bottled at the source completely untouched by human hands until you open the cap.
The Calcium Content in Fiji Water
One of the most common questions from health-conscious consumers is whether Fiji water provides a notable source of minerals like calcium. The answer is yes, it contains calcium, but it is not a significant source of the mineral for daily dietary needs. According to Fiji's own water quality reports, a liter typically contains 18 mg of calcium. To put this in perspective, the recommended daily intake of calcium for most adults is around 1,000 to 1,200 mg. This means you would have to drink over 50 liters of Fiji water to meet the daily requirement, a clearly unrealistic and unnecessary goal, as calcium should be primarily sourced from food.
Fiji Water's Mineral Profile (per liter):
- Calcium (Ca): 18 mg
- Magnesium (Mg): 15 mg
- Silica (SiO2): 92-93 mg
- Sodium (Na): 18 mg
- Potassium (K): 5 mg
- Bicarbonates (HCO3): 153 mg
- Total Dissolved Solids (TDS): ~222 mg/L
Fiji vs. Other Bottled Waters: A Comparison
To better understand Fiji's mineral content, let's compare it to a few other popular bottled water brands. Each water's mineral content is largely dependent on its geological source, leading to unique tastes and mineral profiles.
| Mineral (mg/L) | Fiji | Evian | Perrier (Sparkling) |
|---|---|---|---|
| Calcium | 18 | 80 | 150 |
| Magnesium | 15 | 26 | 4.2 |
| Silica | 92 | ~15 | ~11 |
| Sodium | 18 | 6.5 | 9.5 |
| Bicarbonates | 153 | 360 | 420 |
| pH | 7.7 | 7.2 | 5.5 |
This table illustrates that Fiji's calcium content is lower than some other well-known mineral waters, like Evian and Perrier, but its silica content is significantly higher. The high silica concentration is what contributes to Fiji Water's distinctive soft and smooth mouthfeel. Its moderate mineral balance and alkaline pH of 7.7 also differentiate it from many other brands.
The Importance of Minerals in Water
While Fiji water won't replace a balanced diet, the minerals it does contain are beneficial. Electrolytes like calcium and magnesium are essential for proper hydration and numerous bodily functions. The presence of these minerals, particularly calcium and magnesium, gives water its characteristic taste and contributes to its moderate hardness. Some research also suggests that silica may offer benefits for skin, hair, and nails.
For more information on mineral water benefits, you can consult reputable sources like the World Health Organization (WHO), which provides guidelines on nutrient levels in drinking water. Ultimately, the choice of bottled water often comes down to personal preference regarding taste and feel, which are directly influenced by the specific mineral profile.
The Bottom Line on Calcium and Fiji Water
In conclusion, Fiji water does contain calcium, but not enough to serve as a primary dietary source. Its mineral makeup, including moderate levels of calcium and magnesium and a high concentration of silica, is a natural result of its journey through volcanic rock in a pristine artesian aquifer. While it offers a mild boost of minerals, its main appeal lies in its unique taste, smooth texture, and marketing as a premium, untouched water source rather than its nutritional density. For adequate calcium intake, relying on a balanced diet rich in dairy, leafy greens, and fortified foods is far more effective. For those who appreciate the taste and quality of mineral-enriched water, Fiji provides a viable option with a distinct profile.
Does Fiji Water Have Calcium? Conclusion
Fiji water contains approximately 18 mg of calcium per liter, a trace amount that comes from its natural filtration process through volcanic rock. This calcium, along with other minerals like silica and magnesium, contributes to its unique taste and signature soft mouthfeel. While present, the calcium level is too low to be considered a significant dietary source, and the water is best appreciated for its flavor and sourcing rather than its nutritional content.
