10 Best Mineral Drops For Reverse Osmosis Water
Understand why remineralization is essential explore the top liquid mineral drops that restore key electrolytes like calcium, magnesium, and potassium lost during filtration.


Updated May 12, 2025.

Reverse osmosis (RO) filtration produces very pure water, but it also strips out beneficial minerals (like calcium, magnesium, potassium, and trace elements) that are important for health.
Drinking only demineralized water can leave water “flat” tasting and may contribute to mineral deficiencies over time. Studies show RO removes ~92–99% of calcium and magnesium, increasing the risk of bone loss and fatigue [1].
Adding high-quality trace mineral drops back into RO water restores these nutrients, improving taste, hydration, and health benefits. We’ve compiled the top RO remineralization drops to help you replenish essential electrolytes and enjoy your water again.

How Do RO Water Remineralization Drops Work?
Adding drops to your RO water helps restore essential minerals, such as calcium, magnesium, sodium, potassium, and trace elements like zinc and selenium, which are all important for maintaining healthy bones and teeth, regulating blood pressure, supporting nerve function, and more [2].
These drops not only improve the taste and alkalinity of the water but also provide crucial electrolytes that aid in hydration and overall bodily functions. Not having enough minerals can cause issues like [3]:
- Fatigue
- Muscle cramps
- Imbalance of fluids
Did you know?
Mineral drops can enhance the bioavailability of nutrients and promote better absorption in the body. The drops replenish what's lost to give water nutritional value again, giving them a positive effect on energy levels and recovery.

Why Use Mineral Drops For Reverse Osmosis Water?
The Problem with RO Water
- Mineral Depletion: RO membranes filter out contaminants and nearly all dissolved minerals. The result is water that’s pure but lacks calcium, magnesium, and other electrolytes.
- Health Impacts: Prolonged drinking of low-mineral water can “leach” minerals from the body and may contribute to mineral deficiencies (e.g. weaker bones, muscle cramps, fatigue).
- Flat Taste: Without minerals, RO water often tastes flat or bland. Trace minerals give water a slightly sweeter, rounder flavor, encouraging you to drink more.

Key Minerals Lost in RO Water and Why They Matter
- Calcium: Essential for bone and teeth health, nerve transmission, and muscle contraction [4].
- Magnesium: Cofactor in 300+ biochemical reactions; supports bone strength, muscle/nerve function, and energy production [5].
- Sodium and Potassium: Regulate hydration, blood pressure, and nerve signaling. They are critical electrolytes for fluid balance and muscle function [6].
- Trace Elements (e.g. Zinc, Selenium, Iodine): Support immune function, thyroid health, and antioxidant defenses. Many trace minerals contribute to overall metabolism and thyroid function [7].

Benefits of Remineralizing RO Water
- Improved Taste & Hydration: Adding minerals removes flat taste, making water more palatable. Electrolyte-rich water quenches thirst better than pure H₂O. In other words, you’ll naturally drink more water.
- Nutritional Support: Remineralized water supplies bioavailable calcium and magnesium, supporting bone health and muscle function. Drops may also boost nutrient absorption and energy metabolism
- Balanced pH: Some remineralizing drops add alkaline minerals that can mildly raise RO water’s pH, making it less acidic and gentler on your digestive system.
- Prevent Imbalances: Restoring electrolytes helps prevent symptoms of mineral deficiency (fatigue, cramps, fluid imbalance) that pure water alone might contribute to.

FAQs
Is RO water safe to drink?
Yes, RO water is safe to drink. It’s purified by removing contaminants like bacteria, heavy metals, and chemicals.
Can RO water dehydrate me?
No, RO water will not dehydrate you. It hydrates just like other water.
Can RO water cause constipation?
RO water itself doesn’t cause constipation, but drinking only demineralized water over time may contribute if you’re low on essential minerals like magnesium.
Is RO water free from microplastics?
Yes, RO (reverse osmosis) water is generally free from microplastics. RO membranes filter particles as small as 0.0001 microns, small enough to block most microplastics.
Does RO water have chlorine?
RO systems often include pre-carbon filters that are effective at removing chlorine before the water reaches the RO membrane. Some systems also have a post-carbon filter for further purification.
