What is Magnesium, and where does it actually come from?
It is one of our favourite questions. Because the answer is genuinely remarkable.
Magnesium is the fourth most abundant mineral in the human body. It plays a role in over 300 biochemical processes. Your muscles need it to contract and relax. Your nervous system needs it to stay calm. Your bones depend on it. Your sleep, your energy, your mood - all quietly connected to how much magnesium your body has available.
And yet most of us are running low. Soil depletion, stress, processed food, and the demands of modern life have left a significant portion of the population deficient without even knowing it.
So where do you find it? And more importantly, where does ours come from?
Millions of years in the making
THE ANCIENT TIBETAN SEA
The Magnesium in every Koa product begins its journey somewhere extraordinary. Long before the Himalayas existed, an ancient body of water known as the Tibetan Sea covered much of what is now Central Asia. Over millions of years, as the earth shifted and the mountains rose, this sea gradually withdrew. What remained was a mineral-rich landscape, preserved beneath the earth, holding the concentrated legacy of an ancient ocean.
Today, Magnesium Chloride is harvested from these ancient deposits - one of the purest, most pristine sources of magnesium on the planet.
Our Magnesium Chloride is not synthesised or manufactured. It is drawn from the earth as nature intended, and is certified organic in Australia. No shortcuts. No compromise. Just a mineral as old as the mountains themselves, making its way to you.
Not all Magnesium is equal
There are many forms of magnesium available in pill form - oxide, citrate, glycinate, sulphate, chloride. They are not all the same. And the form matters as much as the source.
We choose Magnesium Chloride for one important reason: bioavailability via the skin. Applied topically, Magnesium Chloride absorbs efficiently through the skin, bypassing the digestive system entirely and delivering its restorative benefits directly to the tissues and bloodstream that need it most.
This is what makes transdermal magnesium so powerful. You feel it where you need it. A tense muscle softens. Restless legs settle. The mind begins to quiet. Not because something foreign has entered your system, but because something your body already recognises has been returned to it.
What your body does with it
Magnesium supports your body in ways that are easy to overlook - until you no longer have enough of it.
- Muscle recovery and relaxation after exercise or
physical strain
- Deep, restful sleep by regulating melatonin and
calming the nervous system
- Reduced anxiety and a greater sense of calm - magnesium is nature's own relaxant
- Hormonal balance, including reduced hot flushes and better mood regulation during perimenopause
- Bone density and joint health, especially important as we age
- Energy production at a cellular level, keeping you feeling vital rather than depleted
Sound familiar? We hear from so many of our customers that they did not realise how much their body was missing until they started using Koa. That is not a coincidence. It is magnesium doing what it has always been designed to do.
Tangaroa and the Gift of the Sea
THE OCEAN AND US
In te ao Māori, the ocean is the domain of Tangaroa, atua of the sea. The sea does not simply exist - it sustains. It gives oxygen, food, and life to every living thing on earth. It regulates our climate. It holds entire worlds beneath its surface.
At Koa, we draw deeply from this understanding. Our magnesium is ocean-born. Our Kawakawa is forest-grown, the
gift of Tāne Mahuta. Together, they embody our founding belief: that where the forest meets the sea, something restorative and extraordinary is possible.
"The earth does not belong to us. We belong to the earth."
Choosing sea-sourced, certified organic magnesium is not just a formulation decision. It is a statement of values. That we source with intention. That we protect Papatūānuku. That we take only what she freely offers, and we do so with gratitude.
Something worth knowing
WHAT THIS MEANS FOR YOU
We want you to know what you are
using. Not just because transparency matters - though it does - but because the story behind your Koa magnesium is genuinely beautiful.
The butter you smooth into your skin at the end of a long day. The oil you reach for when your muscles are tired and your mind will not slow down. The flakes you add to a warm evening bath. Every one of these carries millions of years of natural history, sourced from one of the earth's most ancient and pristine environments.
That is not something we take lightly. And we hope, now that you know it, you will not either.
This is the Koa difference. Not just what we put in. But where it comes from, how it is harvested, and what it stands for.
