What Makes Mineral Salts from Deep Underground Special for Soaking?
Ever wondered why you feel so good immersed in mineral-rich water? That’s because subterranean mineral salts — such as those from geothermal springs, the Dead Sea or Himalayan deposits — are rich in natural minerals your body needs.
These types of salts are unique because they are pure, packed with minerals and scientifically verified to be beneficial to the skin, muscles, and overall health.
Allow me to show you some of the wonders these salts can provide. I’ll also discuss why they’re so effective, how they work and why you can consider adding them to your self-care regimen.
Believe me after this post, you will want to soak in mineral-rich water as much as your schedule will allow.
What Makes Deep Underground Mineral Salts So Special?
Underground mineral salts are nature’s multivitamins. They’re made over thousands of years, acquiring a unique mixture of minerals that table salts simply don’t have. Consider them the gold standard of salts.
A Goldmine of Minerals
Consider Himalayan Pink Salt, for instance. This salt is not only just easy on the eyes: It packs more than 80 naturally occurring minerals and trace elements.
It’s also a source of magnesium, potassium, calcium, copper and iron, among other goodies. Dead Sea Salts even pack a punch with magnesium chloride, potassium chloride, sodium chloride, bromide, calcium chloride, and sulfate.
Here is a quick look at what you’d find in brines from deep sources:
Mineral | Mean % in Deep Brines |
Sodium Chloride (NaCl) | 81.97–91.94% |
Potassium | 0.63% |
Calcium | 1.16% |
Magnesium | 0.72% |
Sulfur | 1.3% |
Iron | 0.17% |
Zinc | 0.13% |
Iodine | 0.72% |
To be sure, these percentages looks small but believe me, they’re a shock to the system. Your body seeks out these minerals and it knows exactly what to do with them.
How Do These Minerals Actually Work?
You might be asking yourself: “Are these minerals actually absorbed by my body?” The short answer is yes. Mineral rich water: Studies have shown that the nutrients in mineral-rich waters can pass through your skin barrier and into your bloodstream.
Science Backs It Up
In a 19-person study, healthy volunteers bathed in Epsom salts for 12 minutes a day for seven days.
The results? Dose-dependent increases in magnesium and sulfate concentrations in their blood and urine. That’s evidence the minerals aren’t sitting on your skin so much as soaking in.
So how much time do you need to spend soaking? 2–3 times a week is the advice from the experts.
For maximum results, use 500–600 grams of mineral salts per bath. That’s roughly 1–1.5 cups, depending on the size of your tub.

The Geochemical Origins of These Salts
Did you ever wonder how these salts come to be? It is a process that occurs over thousands, sometimes millions, of years.
Step 1 is Mother Nature: Deep underground mineral salts gather a diversity of elements that just don’t exist in surface or industrial salts.
Salt contents of natural brines are between 0.1 and 41.3% wt/wt. Maximum levels occur in deep wells and springs. Which means the salts you’re soaking in are not only pure but highly concentrated.
