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.
So while your water looks perfect, it might be missing its soul.
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.
The water with TDS below 100 mg/L may taste flat and lack essential minerals, while levels between 300–600 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 300–500 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.
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.
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 whenever you can.
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
Hydration is not just about water intake it’s about how your body uses that water. Minerals play a key role in that process.
Advocate for Better Water Policies
Public health agencies tend to focus only on removing contaminants. But water standards must evolve they should also consider what’s left behind.
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.
In a world obsessed with purity, maybe it’s time to ask a different question:
Is your water truly healthy?
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 + mineral-rich water?
That is wellness.
