Why Remineralize Your RO Water?
Reverse osmosis offers a high degree of water purification, making it a popular choice for safe drinking water. However, its effectiveness comes at a cost: it removes beneficial minerals like calcium, magnesium, and potassium along with harmful contaminants. This can result in water that tastes 'flat' and, over time, could lead to potential mineral deficiencies if your diet doesn't compensate adequately. Restoring these minerals is key to both improving the water's taste and supporting your body's functions.
Health and Hydration Benefits
Remineralized water goes beyond just taste. The added electrolytes, like sodium, magnesium, and calcium, play vital roles in the body. They aid in nerve function, muscle contraction, and maintaining proper hydration levels. Electrolyte-rich water is more effectively absorbed by the body, quenching thirst more quickly than demineralized water. Furthermore, adding alkaline minerals helps to restore a more balanced pH level, which many prefer for its smoother taste.
The Simple Salt Solution: How Much to Add
The most straightforward method for remineralizing RO water is to add a small amount of mineral-rich salt directly to the gallon. The key is to use the right type of salt and the correct ratio to avoid a salty taste while gaining the benefits. Many experts recommend using Himalayan pink salt or high-quality Celtic sea salt, as these contain dozens of trace minerals beyond just sodium chloride.
For a standard gallon (approximately 3.8 liters) of RO water, the general recommendation is to add 1/4 teaspoon of fine Himalayan pink salt. If you find the taste too mild, you can increase this slightly, but be cautious not to exceed 1/2 teaspoon per gallon, as this may start to produce a noticeable salty flavor. If using a coarse salt, ensure it is fully dissolved by stirring thoroughly. For a single glass, a tiny pinch is sufficient.
Beyond Salt: Other Remineralization Options
While adding salt is a popular and inexpensive method, it's not the only way to remineralize your RO water. Other options offer different levels of convenience, cost, and mineral profiles.
Other DIY Methods
- Mineral Drops: Concentrated liquid solutions, like ConcenTrace mineral drops, are available for purchase and contain a broad spectrum of trace minerals. A few drops per glass or gallon is all that's needed, offering a convenient, customizable, and travel-friendly option.
- Electrolyte Powders: These pre-formulated mixes, often sugar-free, provide a balanced blend of electrolytes like calcium, magnesium, and potassium. They are designed for easy mixing and can also add a hint of flavor, making hydration more appealing.
Integrated Systems
- Inline Mineral Filters: For those with a permanent RO system, adding an inline remineralization cartridge is the most convenient, 'set it and forget it' option. These filters are installed after the RO membrane and automatically add minerals as water flows through, ensuring every drop from the faucet is perfectly remineralized.
- Alkaline Water Pitchers: These use a special filter media to raise the pH and add beneficial minerals like calcium and magnesium. While effective for smaller batches, they require manual refilling and more frequent filter replacement than inline systems.
Comparison of Remineralization Methods
| Method | Cost | Convenience | Mineral Spectrum | Taste Profile | Notes |
|---|---|---|---|---|---|
| Himalayan Salt | Very Low | Low (Manual Dosing) | Good (Trace Minerals) | Mildly Salty | Inexpensive, but requires manual measurement for each batch. |
| Mineral Drops | High | High (Portable) | Broad (70+ trace minerals) | Can be strong | Very convenient for on-the-go or small volumes. |
| Inline Filters | Medium | Very High (Automated) | Variable (Calcium, Mg, etc.) | Polished, balanced | Best for household use; consistent results without effort. |
| Alkaline Pitchers | Medium | Medium (Manual Batch) | Limited (Calcium, Mg) | Improved | Good for smaller volumes; requires regular filter changes. |
Best Practices for Remineralization
When adding salt to your RO water, a few practices ensure you get the best results:
- Start Small: Begin with the recommended 1/4 teaspoon per gallon and adjust to your personal taste preference. It's easier to add more than to correct overly salty water.
- Use Fine Salt: Fine-ground salt dissolves more quickly and evenly, preventing concentration at the bottom of your container.
- Stir and Store: Mix the water thoroughly after adding the salt. Storing the remineralized water in a glass container helps maintain freshness.
- Balance with Diet: While remineralized water adds beneficial trace minerals, it should not be relied upon as a primary source. A balanced diet rich in fruits, vegetables, and whole foods remains the best way to ensure adequate mineral intake.

Conclusion
Adding a small amount of mineral-rich salt, specifically about 1/4 teaspoon of fine Himalayan pink salt to a gallon of RO water, is a simple and effective way to restore lost minerals and significantly improve its taste. This practice helps to reintroduce essential electrolytes and achieve a more balanced pH, enhancing your hydration experience. While DIY salt addition is a great starting point, other convenient and comprehensive options, such as mineral drops or inline remineralization filters, are also available depending on your needs. By taking this small step, you can transform your purified, but mineral-stripped, water into a more refreshing and beneficial source of hydration.
