Magnesium in body care – what is it and why is it used in creams?
Magnesium is the fourth most common substance in the body and an essential mineral that plays a role in some of the body's most fundamental processes. At the same time, magnesium is often mentioned in conversations about calm, recovery, tension and general well-being.
But why do we talk so much about magnesium – and what is it really? Why does it appear in supplements, in body care and now also in our Calming Cream ?
For many, magnesium is primarily associated with dietary supplements. However, magnesium is found naturally in the body – and increasingly in body care products such as creams, sprays and bath salts. This has made magnesium a mineral that many have become curious about, and which is taking up more space in conversations about the body, well-being and care.
In this article, we delve into what magnesium is, what role it plays in the body, how we typically get it through our diet – and how magnesium is used in body care.

What is magnesium – and why is it important for the body?
Magnesium is a naturally occurring mineral found in all cells of the body. It is involved in more than 300 enzymatic reactions – small biological processes that help the body produce energy, build proteins and maintain cells, among other things.
In the body, we typically have around 20–30 grams of magnesium, the majority of which is stored in bones and soft tissue – including the muscles.
In short: Magnesium is not an “extra” mineral, but part of the body's basic machinery.
What does magnesium do in the body?
Magnesium is available in several forms, including Magnesium Citrate, Magnesium Glycinate, Magnesium Malate, Magnesium Taurate, Magnesium L-Threonate, Magnesium Oxide and Magnesium Chloride (which is often used in body care, and the one we use - it is absorbed well through the skin).
Each form of magnesium has its own abilities and function in the body, and when taking them as a dietary supplement, it is important to keep in mind which form of magnesium is used in the supplement. Magnesium is essential for the body to function properly, and it is involved in, among other things:
-
Normal muscle function – including tension and relaxation
-
Function of the nervous system and transmission of nerve impulses
-
Energy metabolism in the body's cells
-
Protein synthesis and enzyme activity
-
Maintaining electrolyte balance
Because magnesium is involved in so many processes, it is often associated with experiences such as relaxation, recovery, fatigue and tension – without this meaning that magnesium alone is a solution to these conditions.
Magnesium through diet and as a dietary supplement
Magnesium is essential for the body's vital functions, but don't panic: A varied diet covers most of the body's magnesium needs. Magnesium is found in, among other things:
-
Whole grain products such as oatmeal and whole grain bread
-
Nuts and seeds, such as almonds, cashews and pumpkin seeds
-
Legumes like lentils and chickpeas
-
Green leafy vegetables like spinach and kale
-
Dark chocolate (yes – win win)
Some people choose to supplement with magnesium as a dietary supplement, for example if their diet is one-sided. However, it is important to remember that dietary supplements are a supplement – not a treatment.
Magnesium and the changing body
The body is not static. Energy, tension, sleep and needs can be experienced differently throughout the cycle and throughout life.
Magnesium is often mentioned in conversations about these changes because the mineral is associated with normal muscle and nervous system function. At the same time, it is important to be clear: Magnesium cannot “solve” cyclical or hormonal changes by itself.
At Flow, it's not about one solution – but about attention and physical care, adapted to the body's needs right now.
Magnesium in body care – what do we know?
Today, magnesium is found in many forms of body care, such as creams, lotions and sprays. Research is still ongoing into the extent to which magnesium is absorbed through the skin, and whether it occurs in significant amounts.
While magnesium through diet is well documented, knowledge about magnesium in body care is still an area under investigation. Therefore, magnesium in skin care is not about guarantees or miracles – but about context, sensation and bodily practice. However, many athletes, children with growing pains or, for example, pregnant women with restless legs can experience great joy from care products with added magnesium.
For many, the value lies in the ritual itself: Touch, repetition, and quiet moments where the body is met with attention rather than expectations.
How is magnesium used in creams and body lotions?
It is precisely with this approach that we have developed Calming Cream – the first product in our Flow Care series.
Have you tried a magnesium spray before?
They often have a high concentration of magnesium, and it can feel a little strange on the skin. That's why it's often recommended to use a body lotion first - before spraying on the skin.
We have chosen to combine the two in our Calming Cream : A nourishing, moisturizing body lotion with the highest possible magnesium content - without compromising on consistency or feel on the skin (if the content had been higher, it would have been significantly more difficult to spread).
How we recommend using Flow Calming Cream
Calming Cream is a wonderfully moisturizing body lotion for everyday use and created as an invitation to calm, touch and repeat. Calming Cream is developed as a body care product – not as a medicine. You can also use it, for example:
-
Before bed
-
After bath
-
As part of a relaxing body massage
-
On days when the body feels restless or overstimulated
A ritual can take 2 minutes or 10. Either is enough. There are no right or wrong ways – only what makes sense for you.
FAQ
Who benefits from Calming Cream?
Everyone can use our body lotion with magnesium, and it is particularly suitable for nighttime restlessness during, for example, pregnancy, menstruation, for children with growing pains, and in connection with exercise.
Should you choose magnesium spray or cream?
It's a matter of taste - a spray will typically have a higher content, as it doesn't contain much else than water. Whereas a cream, for natural reasons, also contains other ingredients and therefore has less room for magnesium (which will also negatively affect the texture of the cream).
What kind of magnesium is used in body care?
It is magnesium chloride - magnesium in salt form which is found in the sea, used in food, makeup and care products.
Is Calming Cream suitable for sensitive skin?
Calming Cream is dermatologically tested and developed with a focus on being gentle on the skin. If you have very sensitive skin or a tendency to allergies, we always recommend testing the product on a small area first.
When should you avoid magnesium products on the skin?
Since they contain magnesium chloride, which is magnesium in salt form, it can sting on damaged skin - for example, freshly shaved skin, cuts or wounds.
