The Natural Mineral Composition of Fiji Water
Fiji water is sourced from a protected artesian aquifer in the remote Yaqara Valley on the island of Viti Levu. Its unique journey through ancient volcanic rock is what defines its distinct mineral profile and taste. Rather than being artificially infused, these minerals are absorbed naturally, creating a signature combination of electrolytes and dissolved solids. The total dissolved solids (TDS) in Fiji water typically hover around 222 mg/L, classifying it as a water with a low to moderate mineral content compared to some European mineral waters, but more substantial than many purified bottled waters.
Key Minerals and Their Concentrations
The most commonly cited and significant minerals found in Fiji water include silica, calcium, and magnesium. However, official reports from the company and reliable bottled water sources detail a more comprehensive list of dissolved minerals and ions that contribute to its overall chemistry and flavor profile. These concentrations are typically measured in milligrams per liter (mg/L). A breakdown of these key components includes:
- Silica (SiO2): One of the most talked-about minerals in Fiji water, with a concentration of around 93 mg/L. It is responsible for the water's smooth, soft mouthfeel and is a natural source of the 'beauty element'.
- Calcium (Ca): Found at approximately 18 mg/L. Calcium is an essential mineral for bone health and proper bodily function.
- Magnesium (Mg): The concentration is about 15 mg/L. Magnesium is another vital electrolyte involved in over 300 biochemical reactions in the body.
- Bicarbonate (HCO3): With levels around 152 mg/L, bicarbonate helps maintain the water's slightly alkaline pH of 7.7.
- Sodium (Na): Typically 18 mg/L. This is a fundamental electrolyte for nerve and muscle function and hydration.
- Potassium (K): Measured at approximately 4.9 mg/L. This is another essential electrolyte for maintaining fluid balance and nerve signals.
- Chloride (Cl): The concentration is around 9.3 mg/L. Chloride is a key electrolyte that works with sodium to balance body fluids.
- Sulfate (SO4): Found in very low amounts, around 1 to 2 mg/L.
- Fluoride (F): A trace amount of 0.24 mg/L is present.
The Artesian Filtration Process
Fiji water's mineral content is a direct result of its unique geological journey. The process begins with tropical rainfall in a pristine rainforest environment. This rainwater seeps deep into the earth and is naturally filtered through layers of ancient volcanic rock over many years. As the water travels through these rock layers, it collects and absorbs minerals like silica, calcium, and magnesium. The water is contained within a pressurized, natural artesian aquifer, which is shielded from external elements. This natural pressure pushes the water to the surface, where it is bottled directly from the source without ever being touched by human hands. This process is critical to the purity and consistent mineral content of the final product.
How Fiji's Mineral Profile Affects Taste and Health
Fiji water is celebrated for its soft and smooth taste, and this is directly attributed to its distinctive mineral makeup. The high level of silica is the primary contributor to this unique mouthfeel, giving it a palatable and almost silky texture that distinguishes it from many other brands. Beyond taste, the mineral content provides a source of natural electrolytes that are essential for hydration and many bodily functions, including nerve and muscle function and blood pressure regulation. While the mineral content is not high enough to be considered a curative water like some other mineral waters, the balanced combination is beneficial for general hydration.
Comparison of Bottled Water Mineral Content
To understand Fiji water's position in the bottled water market, it is helpful to compare its mineral profile with other well-known brands. The table below provides a quick comparison of the total dissolved solids (TDS) and key mineral concentrations (in mg/L) for several popular brands.
| Water Brand | TDS (mg/L) | Silica (mg/L) | Calcium (mg/L) | Magnesium (mg/L) | pH | Taste Profile | Source Type |
|---|---|---|---|---|---|---|---|
| Fiji | ~222 | ~93 | ~18 | ~15 | 7.7 | Soft, smooth | Artesian Aquifer |
| Evian | ~345 | - | - | - | 7.2 | Balanced, mineral-rich | Spring |
| Voss | ~44 | - | - | - | 5.5-6.0 | Very pure, low mineral | Artesian |
| San Pellegrino | ~1109 | - | - | - | - | Distinct, high mineral | Mineral Spring |
| Acqua Panna | ~188 | - | - | - | - | Smooth, light | Spring |
This table illustrates that Fiji water, with its specific TDS and high silica content, offers a distinct mineral balance that is softer than high-mineral waters like San Pellegrino and more mineral-rich than ultra-low mineral waters like Voss.

Conclusion
Fiji water contains a naturally derived and consistent blend of minerals, including significant amounts of silica, calcium, and magnesium, alongside sodium, potassium, and bicarbonates. These minerals are sourced from a pristine artesian aquifer on the remote island of Viti Levu, where tropical rainwater is filtered through volcanic rock. The result is a bottled water with a characteristic soft, smooth taste and a moderately low mineral content that provides natural electrolytes for hydration. Understanding this specific mineral composition sheds light on why Fiji water tastes and feels different from many other bottled and tap water options available on the market.
