Clean Isn't Always Healthy: The Hidden Truth About Mineral Loss in Modern Water

You have heard it a thousand times: drink more water, it's good for you. We buy purifiers, prefer bottled water and avoid anything that looks cloudy. But here's something you probably have not thought about, what if our water has become too clean?

In the quest for purity, we may have stripped away more than dirt and germs. We might also be removing nutrients your body quietly depends on.

Water isn't just H₂O

When you see a clear glass of water, it's easy to think it's just hydrogen and oxygen. But natural water from rivers, springs and wells carries tiny amounts of minerals that play big roles in your health:

• Calcium builds strong bones and teeth
• Magnesium supports heart rhythm, muscles and energy production
• Potassium balances fluids and blood pressure
• Fluoride protects your teeth from decay

These minerals are part of what makes natural water alive and nourishing. But today's "purified" water, whether from your home filter, desalination plant or bottle, is often stripped bare.

• Desalinated water, made by removing salt from seawater, loses nearly all minerals.
• RO filters (reverse osmosis) eliminate everything, good and bad.
• "Purified" bottled waters often have extremely low Total Dissolved Solids (TDS), meaning they're practically demineralised.

Why mineral-free water isn't as harmless as it looks

For decades, health authorities focused on removing contaminants from water, microbes, heavy metals and chemicals. That's crucial, no doubt. But now research is asking a new question: what happens when we remove too much?

Understanding TDS

TDS (Total Dissolved Solids) is a measure of the combined content of all minerals, salts and metals dissolved in water, including calcium, magnesium, sodium, potassium and bicarbonates.

Water with TDS below 100 mg/L may taste flat and lack essential minerals, while levels between 300 and 600 mg/L are generally considered optimal for both taste and health. When TDS drops below 50 mg/L, water is classified as very low-mineral and may not contribute meaningfully to your body's mineral intake. In other words, if your water's TDS is too low, it might hydrate you but it won't nourish you.

Heart and circulatory health

Magnesium is one of the most critical minerals for heart function. Low magnesium intake has been linked to higher blood pressure, arrhythmia and even sudden cardiac death. A European clinical study found that adults drinking mineral-rich water experienced lower blood pressure and better lipid profiles within weeks compared to those consuming low-mineral or desalinated water.

Pregnancy and early development

Pregnant women and infants are particularly vulnerable to mineral deficiencies. Studies have shown that low-calcium and low-magnesium water may increase risks of:

• Preeclampsia
• Premature birth
• Low birth weight

That's because these minerals help maintain normal muscle tone, blood circulation and fetal growth. When both diet and water are low in minerals, the body has little reserve to draw from.

Bone and growth health

For children and teens, calcium and magnesium are essential to build bone mass. Research suggests that kids drinking low-mineral water, especially in regions using RO filtration, have softer bones and higher fracture rates. Over time, adults may also face issues with bone density and muscle weakness if their magnesium intake remains chronically low.

Other health concerns

• Ultra-pure water is aggressive, it can leach metals like lead or copper from household plumbing.
• Long-term consumption has been linked to electrolyte imbalances, slower hydration and altered taste perception.
• Some reports even suggest potential connections to nerve disorders and metabolic diseases, though more studies are needed.

The irony? The water we've worked so hard to purify might not be as health-promoting as we thought.

How did we get here?

It started with good intentions. The 20th century brought a wave of innovation in water safety: filtration, chlorination, desalination. These technologies helped millions avoid waterborne diseases. But somewhere along the way, purity became the only goal.

Desalination

Countries using desalinated seawater (like parts of the Middle East, Australia and coastal India) produce water almost free of minerals. While some plants add back calcium to prevent pipe corrosion, magnesium is rarely reintroduced, leaving the water imbalanced.

Home filtration

Household filters, especially reverse osmosis systems, are designed to remove contaminants, but they don't differentiate between harmful particles and essential minerals. Unless you use a remineralisation cartridge, your drinking water is essentially distilled.

Bottled water

"Purified water" sounds premium, but it often just means filtered tap water with almost no minerals left. Labels showing TDS below 50 mg/L indicate very low mineral content, far below the 300 to 500 mg/L found in natural spring water. The result? A generation drinking "perfectly pure" water that's nutritionally empty.

What you can do: simple steps to healthier hydration

You don't need a lab or a special gadget. Just a bit of awareness can make a real difference.

1. Know your source.
   • If you use a home filter, check if it removes all dissolved solids.
   • Look up your local water report, desalinated water is common in many coastal cities.
   • Read bottled water labels. If it says "purified," "distilled," or "low mineral", that's your clue.
2. Choose mineral-friendly options.
   • Pick bottled water with calcium and magnesium listed on the label.
   • Use RO systems with remineralisation filters that add these minerals back.
   • Consider natural spring or mineral-rich water for at least part of your daily hydration.
3. Balance through diet. If your water is mineral-poor, ensure your diet is mineral-rich:
   • Calcium: milk, curd, sesame seeds, tofu, ragi
   • Magnesium: nuts, seeds, lentils, whole grains
   • Potassium: bananas, avocados, leafy greens
4. Advocate for better water policies. Encouraging remineralisation at municipal levels, or including minimum magnesium and calcium guidelines, could make community water supplies safer and more balanced.

The Lyxaa takeaway

Water gives life, but it's supposed to nourish life, too. Your body doesn't just need water that's clean. It needs water that supports your cells, strengthens your bones and fuels your energy.

At Lyxaa, we believe wellness starts with awareness. That's why we offer TDS testing to help you understand exactly what's flowing through your glass, and remineralisation facilities to restore the essential minerals your body needs. Because clean water is good. But clean and mineral-rich water? That is wellness.
