Premium Deep Sea Water sourced from 510 meters beneath Korea's East Sea. Naturally balanced mineral profile Mg:Ca:K = 3:1:1. No additives, no processing. 20 bottles · 500mL each · BPA Free · pH 6.5.
Why it works
The natural mineral balance helps water move through the body more efficiently than demineralized water.
Naturally occurring magnesium, calcium and potassium support normal fluid and electrolyte balance through the day.
Magnesium and potassium contribute to normal muscle contraction and nerve signaling, during and after activity.
Hydration support with no added sugars, stimulants, or artificial ingredients. Suitable for consistent daily intake.
Bottled in BPA-free, recyclable PET and made using low-temperature, closed-loop processing designed to reduce waste and preserve water integrity.
Mineral profile
Magnesium supports normal muscle and nerve function. Deep-sea water naturally carries magnesium at roughly three times the calcium ratio.
Naturally occurring calcium, held in a balanced ratio with magnesium rather than dosed in after the fact.
Potassium is a key electrolyte for fluid balance. A balanced ratio supports normal hydration during and after activity.
Sourced from 510 meters beneath the East Sea, the water carries a naturally balanced pH of 6.5, with no artificial additives. A profile that reflects its deep-sea origin.
No added flavors, preservatives, or artificial minerals. Deep-sea mineral water, cleaned to strict safety standards with its natural mineral balance kept intact.
Our source
Our water is sourced from 510 meters beneath the East Sea of Korea, a rare geological environment where deep ocean water exists close to shore.
At this depth, sunlight cannot penetrate and modern contaminants cannot reach, allowing the water to remain cold, stable, and naturally mineralized.
The East Sea is known for its steep continental shelf and slow circulation, preserving deep water layers isolated from the surface. That natural protection keeps the mineral balance and clarity consistent.

Questions
Unbelievable Water begins 500+ meters below the surface of the East Sea, in cold, dark, stable deep water where sunlight and most surface contaminants never reach. A dedicated deep-sea intake and offshore pipeline move that water through sealed, temperature-controlled infrastructure straight to our facility, protecting it from surface exposure.
At the plant, the water goes through primary and secondary reverse osmosis to remove unwanted substances, followed by precise mineral concentration steps. The goal is simple: clean the water to strict safety standards while keeping its natural mineral balance intact, rather than stripping it and adding minerals back later. It is then held in controlled storage, batch-tested for taste, clarity, microbes, and key minerals, and only then bottled.
Many mineral waters have imbalanced mineral profiles. Unbelievable Water's naturally occurring 3:1:1 ratio of magnesium to calcium to potassium reflects an electrolyte balance associated with hydration, recovery, and normal muscle and nerve function.
