Ultranano filtration systems, such as your ultranano-drink, remove nearly all impurities from the water with the highest precision—including heavy metals, pesticides, pharmaceutical residues, microplastics, and bacteria. During this purification process, natural minerals such as calcium, magnesium, and trace elements are also removed.

The result is extremely pure water with a characteristically neutral to slightly bland taste. The mineral-drink replenishes these natural minerals in an ionized, highly bioavailable form, bringing your water up to the standard of high-quality mineral waters and natural mountain springs.

Remineralization significantly improves the taste and raises the pH level—just like with premium spring waters. This gives you the best of both worlds: absolute purity through filtration and natural mineralization for a full-bodied taste and spring-water character.

When combined with an ultranano-drink system, the roles are clearly defined. The ultranano-drink reduces unwanted contaminants and harmful substances through its exceptionally fine ultranano-filtration, thereby laying the foundation for high-quality drinking water. The mineral-drink is installed as the final system before the water faucet and enriches the already filtered water with natural minerals such as calcium and magnesium, as well as other trace elements. This results in a balanced combination of intensive filtration and subsequent mineral enrichment.

Our authentic Okinawa Sangoku coral comes from controlled, sustainable sources around the Japanese island of Okinawa. Harvesting takes place under the strict supervision of the Japanese government and environmental protection agency.

No overexploitation of living coral:

No living corals are harvested for our product. The Sangokoralle we use is fossilized material from the seafloor that has been deposited over thousands of years.

Coral particles naturally detach from the reefs and sink to the seafloor, where they fossilize—it is precisely this fossilized material that is mechanically extracted.

Japanese authorities ensure that no living coral structures are harmed. The removal of deposited fossil particles can even be beneficial for living corals, as it gives them more space and light.

Sustainability Through Regulation:

Extraction is strictly limited and continuously monitored. Only selected, licensed manufacturers are permitted to harvest fossilized Sangokoralle under government supervision. This oversight protects the sensitive ecosystem of the coral reefs while guaranteeing a natural product of the highest quality.

Every batch of our Okinawa Sangoko coral is thoroughly tested for heavy metals, toxins, and impurities before it is approved for production.

Heavy metal testing in accordance with international standards:

Testing is conducted in accordance with the regulations of international pharmacopoeias (Ph. Eur. 2.4.8, USP 232). This involves analyzing critical elements such as lead, arsenic, cadmium, mercury, and other potentially harmful metals. Only material that falls below the strict limit values is used.

Purification process:

After extraction, the Sangokoralle undergoes a special, patented purification process. Any impurities that may have accumulated in the fossilized material are completely removed. At the same time, the minerals are activated so that they ionize immediately upon contact with water.

Among the 2,500 known coral species worldwide, the Okinawa Sangoko coral is unique: it is the only one whose mineral composition is nearly identical to that of the human body. This bioidentical structure makes it the ideal material for water remineralization.

Optimal calcium-magnesium ratio:

Sangok coral contains calcium and magnesium in a natural 2:1 ratio—exactly the same composition found in the human body. Scientifically, a ratio between 1.7 and 2.6 is considered optimal for the absorption of both minerals; at 2:1, Sangok coral falls perfectly within this range.

Over 70 trace elements in bioactive form:

In addition to calcium and magnesium, Sangokoralle contains more than 70 other minerals and trace elements—including iron, zinc, selenium, manganese, and iodine. These are present in an ionized, naturally bound form.

The Okinawa Connection:

The island of Okinawa is known worldwide as a “Blue Zone”—a region with exceptionally high life expectancy. Studies have identified, among other factors, the mineral composition of the drinking water—which flows through Sango coral rock and is naturally mineralized—as a key factor.

Compared to synthetic mineral blends, Sango coral offers a complete, natural mineral matrix—bioidentical, highly bioavailable, and optimally balanced.

Yes, remineralization can noticeably affect the taste of the water. Many users find that, after being enriched with natural minerals, the water tastes more balanced, full-bodied, and pleasant for everyday use.

The ultranano-drink remains the central stage of the treatment process, while the mineral-drink refines the resulting taste. When used in combination, this creates a water profile that is focused on both purity and balanced minerality.

No, the mineral-drink is not a standalone water filter and does not replace the ultranano-drink. The actual filtration is still performed by the ultranano-drink. The mineral-drink is a downstream addition that connects to the already filtered water and remineralizes it. That is precisely why the combination is structured so clearly: first filtration, then natural mineral enrichment.

This combination is ideal for people who want both very fine filtration and a more balanced mineral profile in their trinkwasser. The ultranano-drink forms the basis for high-quality water treatment right at the point of use. The mineral-drink complements this system for anyone who prefers filtered water with natural mineral enrichment. The result is a solution that combines high standards for water quality, practicality for everyday use, and great taste.

The mineral-drink cartridge was primarily developed for the ultranano-drink system. However, thanks to its standardized 1/4” connections, it is also technically compatible with other filtration systems that use 1/4” tubing.

Compatibility with other systems:

All you need is a 1/4” hose—the industry standard for osmosis and water filtration systems. The quick-connect fittings are compatible with most common 1/4” connections.

Important Note – No Warranty Outside of Dropvital Systems:

We do not provide any warranty for any use of the mineral-drink cartridge with systems other than dropvital products. We guarantee optimal performance, mineralization efficiency, and product safety only when used in combination with the ultranano-drink system.

Why this restriction? The cartridge is designed to match the specific parameters of the ultranano-drink system:

• Flow rate: Precise contact time between water and Sangokoralle for optimal mineralization
• System architecture: Designed as the final stage following the active-home purifier
• Water quality:Tailored to the TDS and pH values of the ultranano-drink
  

For other systems with different flow rates, pH levels, or initial TDS values, we cannot guarantee either optimal mineralization or product safety. The warranty is void if used outside of dropvital systems.

Our advice:

For the best possible performance and full warranty coverage, we recommend using this product exclusively with your ultranano-drink system.

We recommend replacing the cartridge every 12 months for normal household use (2–4 persons).

Why 12 months?

Remineralization cartridges continuously release minerals into the flowing water. Over time, the mineral reservoir is depleted—the approximately 280g of Sangok coral gradually dissolves and is used up. The service life depends on the water volume, flow rate, and pH level of the incoming water.

How can I tell when it’s time to replace the cartridge?

• Change in taste: The water tastes more neutral and less full-bodied again
• Time-based: The cartridge should be replaced as a preventive measure after 12 months

Important:

There is no danger associated with depleted remineralization cartridges—the water is simply no longer optimally mineralized.

The cartridge is designed as a compact inline solution and was engineered to integrate seamlessly into the ultranano-drink system. This ensures that the expansion is technically sound and tailored to the existing system. Depending on the model and installation situation, setup can be carried out simply and efficiently. If you want to play it safe, you can have the mineral-drink professionally integrated into an existing ultranano-drink system.
