Himalayan Salt: An Ancient Sea and a Lot of Marketing

There's a pink salt grinder on nearly every café table now, sitting next to the pepper like it earned the spot. Somewhere along the way Himalayan salt stopped being a seasoning and became a wellness symbol, a small sign that you'd thought a bit harder about what goes in your body. And the headline claim follows it everywhere you look: 84 minerals, tucked into every rosy crystal.

I'll be straight with you upfront. We put Himalayan salt in Primaldew, so you might expect me to repeat that line. I'm not going to. The "84 minerals" story is one of the most oversold facts in the supplement aisle, and the real reason this salt is worth using turns out to be smaller, quieter, and honestly more interesting than the marketing.

Where pink Himalayan salt actually comes from

Almost none of it comes from the Himalayas. The great majority is mined at Khewra, in the Salt Range of Punjab, Pakistan, a few hundred kilometres from the real mountains. What sits under that ground is the dried-out remains of an ancient sea.

Hundreds of millions of years ago, a shallow sea covered what is now northern Pakistan. Geologists generally place the Salt Range deposits at somewhere around 500 million years old, give or take, back in the deep stretch of time before complex life had even filled the oceans. The water evaporated. The salt it left behind got buried, then folded and shoved upward when the Indian plate crashed into Asia and raised the mountains in the first place. The pink colour comes from a trace of iron oxide. Rust, basically, woven into each crystal as it grew.

That part needs no embellishment. You are seasoning your dinner with a piece of a sea that disappeared before there were fish to swim in it. Which is a genuinely strange and rather lovely thing to sit with while you're salting an egg.

How a humble rock became a wellness icon

It's a fair question how we ended up here. For most of human history salt was simply precious, valuable enough to tax, to fight over, even to pay soldiers with. Then over the past couple of decades pink salt picked up a second life as a lifestyle marker. The glowing lamps. The serving slabs. The grinders in matte packaging that cost five times what a box of table salt does. Almost none of that was about flavour. It was about signalling care, and pink happens to read as natural and ancient and untouched all at once. Marketing found a rock with a beautiful colour and a great origin story, and pushed it about as far as a rock can go.

None of which is a knock on the salt itself. It just helps to separate what's true from what got bolted on later to sell more of it. Take away the lamps and the claims and you're left with a very good cooking salt that happens to be lovely to look at and comes from somewhere remarkable. The trouble only starts when someone tells you it'll fix your sleep or pull toxins out of your body, which it won't, and which no honest label should ever imply.

The "84 minerals" claim, looked at honestly

Here's where things get slippery. Yes, pink salt does contain a long list of elements beyond sodium and chloride. A frequently cited 2020 analysis found meaningfully more of certain minerals than ordinary table salt, on the order of 2,600 to 2,700 mg per kilogram of calcium and magnesium, plus a couple of thousand mg per kilogram of potassium. Laid out on a chart, that looks impressive.

Then you do the arithmetic. Those figures are per kilogram of salt, and nobody eats a kilogram of salt. A heavy day might be five or six grams. Run the numbers and the magnesium you actually get from pink salt is a rounding error next to a handful of spinach or a single square of dark chocolate. To reach a useful dose of any of these trace minerals through salt alone, you'd have to swallow so much sodium that it would do you far more harm than the minerals could ever undo.

And there's a catch the brochures tend to skip. Because pink salt is essentially unrefined, some of what gets locked into the crystal isn't on anybody's wish list. That same line of research flagged that certain samples carried lead and other heavy metals above comfortable levels. Not at panic-inducing amounts for normal cooking, but it's a useful reminder that "contains 84 elements" cuts both ways. A few of those elements you'd honestly rather not be collecting.

Is it lower in sodium than regular salt?

No, and this one trips up a lot of people. Pink salt is still roughly 98% sodium chloride, exactly like the white stuff. If your crystals are big and craggy, a teaspoon of them weighs slightly less than a teaspoon of fine table salt, so by volume you might scoop a touch less sodium. By weight it's a wash. Anyone reaching for pink salt to cut down on sodium is measuring with the wrong ruler.

The iodine trade-off nobody mentions

Regular table salt is usually iodised, and that quiet piece of public health policy erased a great deal of iodine deficiency over the last century. Most pink salt isn't iodised. If it has completely replaced table salt in your kitchen and you don't eat much seafood, dairy or seaweed, that's a small gap worth keeping an eye on. The plain old table salt was doing a job you may never have noticed.

So why is it in Primaldew at all?

A fair question, given everything above. The honest answer has nothing to do with 84 minerals.

Sodium is an essential electrolyte. Your nerves and muscles literally cannot fire without it, and a daily greens blend you stir into water is a sensible place for a small, measured amount of it. It helps your body hold on to and use fluid properly, and, less romantically but just as truly, it makes the whole drink taste like something you'll actually reach for again tomorrow. A greens powder you quit after a week does nobody any good. We chose the Himalayan kind for its clean taste and because it's barely processed, not because we imagine a pinch of it is a multivitamin. You can see exactly where it sits in the full formula on our ingredients page.

If you've read this far, you've probably noticed that we'd rather tell you what an ingredient can't do than oversell what it can. That's deliberate. A formula is only as trustworthy as its least honest claim, and salt is an easy place to start being straight with people. You'll find the same thinking behind every line on our label.

That's the whole pitch, and I think it beats the myth. The salt earns its place by being a good, plain electrolyte with a clean taste and an extraordinary backstory. It doesn't need to pretend to be medicine.

So next time you twist that little grinder, feel free to skip the bit about 84 minerals healing you. The truer story is the one inside the rock: a sea that dried up around half a billion years ago, lifted slowly into the mountains, and ground onto your plate at dinner. That's more than enough.
