Fiji Water Mineral Content: Does Fiji Water Have Electrolytes?
FIJI Water markets itself as having 100% naturally occurring electrolytes and a pH of 7.7. Published product analyses list silica 93 mg/L, calcium 18 mg/L, magnesium 15 mg/L, bicarbonate 152 mg/L and a total mineral content (TDS) of about 222 mg/L.
Does Fiji Water have electrolytes?
Yes. Electrolytes are minerals that carry an electric charge when dissolved in water — sodium, potassium, calcium, magnesium, chloride and bicarbonate all qualify. FIJI Water contains all of these naturally from its volcanic artesian source. The brand's own marketing emphasizes "100% naturally occurring electrolytes," meaning nothing is added — the minerals come from the rock the water filters through underground.
Fiji Water mineral content table
Typical per-liter values reported on Fiji Water packaging and the brand's published analysis:
| Mineral / metric | Amount |
|---|---|
| Silica | 93 mg/L |
| Bicarbonate (HCO₃⁻) | 152 mg/L |
| Calcium | 18 mg/L |
| Magnesium | 15 mg/L |
| Sodium | 18 mg/L |
| Potassium | 5 mg/L |
| Chloride | 9 mg/L |
| Total dissolved solids (TDS) | 222 mg/L |
| pH | 7.7 |
What minerals are in Fiji Water?
FIJI's defining mineral is silica. At ~93 mg/L it is one of the most silica-rich mainstream bottled waters, and silica is what gives FIJI its signature soft, almost silky mouthfeel. The water also carries moderate calcium and magnesium, low sodium, and a bicarbonate level high enough to keep the pH slightly alkaline at 7.7.
Why Fiji Water tastes soft
Two reasons. First, the TDS of 222 mg/L is moderate — less mineral-loaded than waters like Gerolsteiner (~2,479 mg/L) or San Pellegrino (~960 mg/L), so it doesn't have a strong mineral "bite." Second, the high silica content rounds the texture on the palate. Combined with the slightly alkaline pH and still (non-carbonated) format, the result is a smooth, easy-drinking water.
Is Fiji Water alkaline?
FIJI Water sits at pH 7.7, which is mildly alkaline (anything above 7.0 is alkaline). It is not in the "high-alkaline" category like Essentia (pH ~9.5) or Icelandic Glacial (pH ~8.4), but it consistently tests on the alkaline side of neutral thanks to its bicarbonate content. See our FIJI Water pH guide for the full breakdown.
Fiji Water vs Evian vs Deer Park vs Smartwater
| Metric | FIJI | Evian | Deer Park | Smartwater |
|---|---|---|---|---|
| Type | Artesian | Mineral | Spring | Vapor distilled + electrolytes |
| TDS | 222 mg/L | 309 mg/L | ~50–100 mg/L | ~30 mg/L |
| pH | 7.7 | 7.2 | ~7.6 | ~7.0 |
| Calcium | 18 mg/L | 80 mg/L | ~15 mg/L | trace (added) |
| Magnesium | 15 mg/L | 26 mg/L | ~3 mg/L | trace (added) |
| Silica | 93 mg/L | ~15 mg/L | low | low |
| Electrolytes | Naturally occurring | Naturally occurring | Naturally occurring | Added after distillation |
FIJI wins on silica and mouthfeel; Evian wins on dietary minerals; Deer Park is the lightest natural option; Smartwater is essentially pure water with electrolytes added back.
Is Fiji Water good for hydration?
Yes. FIJI Water hydrates as effectively as any still bottled water, and its naturally occurring electrolytes — sodium, potassium, calcium, magnesium — support the same fluid-balance role that sports drinks deliver, without added sugar. For everyday hydration it is more than sufficient; for heavy endurance training or heat exhaustion, you'll still want a higher-sodium electrolyte drink.

Frequently asked questions
What electrolytes are in Fiji Water?
Sodium, potassium, calcium, magnesium, chloride and bicarbonate — all naturally occurring from the artesian source.
How much silica is in Fiji Water?
About 93 mg/L, one of the highest among mainstream bottled waters.
What is the TDS of Fiji Water?
Around 222 mg/L of total dissolved solids — a moderate mineral level.
Is Fiji Water better than Smartwater for electrolytes?
Both deliver electrolytes. FIJI's are naturally occurring from the source; Smartwater's are added back after vapor distillation. Neither is a substitute for a sports drink during heavy exertion.
Is Fiji Water alkaline?
Yes, mildly. Its pH is 7.7 — above the neutral 7.0 line but not in the high-alkaline category.
