Fiji Water is a perfectly fine drinking water with one genuinely notable feature: it contains about 85 milligrams of silica per liter, which is significantly more than most bottled waters. Whether that alone makes it “good for you” beyond ordinary hydration depends on what you’re comparing it to and how much you’re willing to pay for trace mineral differences.
What Makes Fiji Water Different
Fiji Water comes from an artesian aquifer on the island of Viti Levu in Fiji, where rainwater filters through layers of volcanic rock before collecting underground. That geological journey loads the water with dissolved silica, a naturally occurring form of silicon. At 85 mg per liter, Fiji Water has one of the highest silica concentrations of any commercially available bottled water.
Beyond silica, the mineral profile is modest. A standard 500 mL (16.9 oz) bottle contains just 5 mg of sodium, which is essentially negligible. If you’re on a sodium-restricted diet, Fiji Water won’t cause problems. It also contains small amounts of calcium, magnesium, and potassium, though not enough to meaningfully contribute to your daily requirements of any of those minerals.
The Silica Question
Silica is the ingredient Fiji Water’s reputation leans on, and there is some scientific interest behind it. Silicon, the element silica delivers, plays a role in the formation of collagen and connective tissue, and researchers have investigated whether it supports bone health. A clinical trial at the National Institutes of Health studied postmenopausal women drinking one liter of Fiji Water daily (providing 85 mg of silicon) over 12 weeks to measure its effects on bone metabolism.
The theory is biologically plausible. Silicon appears in bone and connective tissue throughout the body, and some observational studies have linked higher dietary silicon intake with better bone mineral density. But the evidence is still preliminary, and no major health organization currently recommends silicon supplementation for bone health. You can also get silicon from whole grains, bananas, green beans, and beer, often in comparable or higher amounts than a liter of Fiji Water provides.
Some people also drink silica-rich water for skin and hair health, based on the logic that collagen production depends partly on silicon. This is a reasonable extension of the same science, but controlled studies confirming visible cosmetic benefits from drinking high-silica water are scarce.
How It Compares to Other Bottled Waters
In terms of basic hydration, Fiji Water does the same job as any other clean drinking water. Where brands differ is in their mineral content and added ingredients. Smartwater, for example, adds electrolytes like calcium chloride, magnesium chloride, and potassium bicarbonate after a distillation process. Essentia markets itself on its alkaline pH of 9.5 or higher. Fiji’s distinction is its naturally occurring mineral profile rather than anything added during bottling.
None of these differences matter much for everyday hydration. Your kidneys regulate your body’s pH regardless of what water you drink, and the electrolyte content of any bottled water is too low to replace what you lose during serious exercise. For that, you’d need a dedicated sports drink or electrolyte supplement. The practical difference between premium bottled waters is flavor and mouthfeel. Fiji’s silica and mineral content gives it a slightly smooth, soft taste that many people find pleasant, which is a perfectly valid reason to prefer it.
Safety and Contaminants
Fiji Water is drawn from a sealed underground aquifer, which provides natural protection from surface-level contamination. The water is bottled at the source without human contact, according to the company. It’s worth noting that a study examining the Nakuvadra-Rakiraki River in Fiji found elevated heavy metals and microplastics in that surface waterway, but this is a completely different water source than the deep artesian aquifer Fiji Water uses. Surface rivers and sealed underground aquifers are not connected in any meaningful way for contamination purposes.
Like all bottled water sold in the United States, Fiji Water must meet FDA standards for contaminant levels. Independent testing over the years has generally found it compliant with those standards.
The Bottle Itself
Fiji Water bottles have never contained BPA, the plasticizer that raised health concerns in other food-grade plastics. Since spring 2023, the company has been producing its 500 mL and 330 mL bottles from 100% recycled plastic (rPET), covering roughly 70% of its total bottle volume worldwide. This doesn’t change anything about the water inside, but it does address one of the most common criticisms of the brand: the environmental cost of shipping water across the Pacific Ocean in single-use plastic.
Is It Worth the Price?
If you’re buying Fiji Water purely for health benefits, the honest answer is that it’s not doing anything your tap water (assuming it’s clean) plus a balanced diet can’t accomplish. The silica content is genuinely higher than most alternatives, but the proven health payoff of that extra silica remains uncertain. You’d spend less money eating a bowl of oatmeal, which delivers silicon along with fiber, vitamins, and other nutrients water can’t provide.
Where Fiji Water does deliver is taste, consistency, and convenience. It’s a clean, pleasant-tasting water with a naturally soft mouthfeel. It’s low in sodium, free of additives, and comes in BPA-free packaging. If you enjoy drinking it and the price doesn’t bother you, there’s nothing wrong with it. But the gap between Fiji Water and ordinary filtered tap water is far smaller than the price difference suggests.
