The mineral your
body runs on —
and runs low on.
Magnesium is involved in more than three hundred processes in the human body. Most women in the West don’t get enough of it. Here’s what it does, why you’re probably short, and exactly where the Reova roller fits — told straight, with no medical overreach.
Fourth most abundant.
Quietly essential.
Enzymatic reactions
Magnesium is a required cofactor in over 300 enzyme systems that regulate biochemical reactions throughout the body — from energy production to protein synthesis.
Most abundant mineral
It’s the fourth most abundant mineral in the human body. Around 60% of it is stored in bone, the rest in muscle, soft tissue and fluids.
Don’t get enough
Population studies suggest roughly half of people in Western countries fall short of the recommended daily magnesium intake.
The body’s quiet regulator.
-
·01
Muscle function
Magnesium plays a central role in normal muscle contraction and relaxation — it acts as a natural counterpart to calcium in the muscle cell.
-
·02
Nervous system
It contributes to normal nerve transmission and supports the regulation of neurotransmitters that calm the nervous system, including GABA.
-
·03
The sleep–wake cycle
Magnesium is involved in the pathways that govern melatonin and the body’s circadian rhythm — part of how the body transitions toward rest.
-
·04
The stress response
It participates in regulating the HPA axis — the system behind the body’s cortisol and stress response. Stress, in turn, depletes magnesium, which can become a cycle.
-
·05
Energy & metabolism
Every molecule of ATP — the body’s energy currency — must bind to a magnesium ion to become biologically active. No magnesium, no usable energy.
-
·06
Bone structure
Around 60% of the body’s magnesium is held in bone, where it contributes to structural integrity alongside calcium and vitamin D.
Modern life is a
magnesium drain.
The recommended intake for adult women is around 310–320mg a day, rising in pregnancy. Most don’t reach it — and several features of a high-performing life actively deplete what’s there.
Stress increases magnesium excretion. Caffeine and alcohol are mild diuretics that flush it. Intense exercise burns through it. Refined modern diets carry less of it than wholefood diets ever did. The result is a slow, quiet shortfall in exactly the women who can least afford to run on empty.
This is the gap Reova was built around — not as a cure, but as a daily, deliberate way to bring magnesium back into contact with your body, through the largest organ you have.
Why a roller, not a pill.
The skin is the body’s largest organ, and transdermal mineral delivery is an active area of research. Magnesium chloride is among the most water-soluble and skin-compatible magnesium salts, which is why it’s the form used in topical magnesium products worldwide.
We’ll be straight with you: the science on how much magnesium is absorbed through skin is still emerging, and we won’t pretend otherwise. What is well established is that magnesium chloride applied to the skin is well tolerated, that the ritual of application supports a genuine sensory wind-down response, and that a roller delivers it precisely to pulse points — wrists, neck, behind the ears — where skin is thin and the application becomes a moment rather than a chore.
A roller is also simply more honest to real life than a bath. You can use it every night, anywhere, in thirty seconds. Consistency beats intensity.
Why Zechstein.
Why 10%.
Why nothing else.
Zechstein source
Our magnesium chloride is drawn from the Zechstein seabed, 1,500 metres beneath the Netherlands — sealed and protected for around 250 million years, among the purest natural sources on earth.
The gentler dose
The topical magnesium industry typically formulates at 15–20%. We chose 10% — meaningful magnesium contact without the harsh sting, so it’s comfortable enough to use every single day.
Ingredients, one active
Distilled water, magnesium chloride, and 1% vegetable glycerin to keep skin conditioned. No fragrance, no preservative, no dye, no filler. The whole label fits on one line.
A cosmetic, not a cure.
What we will and won’t claim
Reova is a cosmetic product for external use — not a medicine and not a food supplement. Everything above describes the role of magnesium in the body generally, drawn from established nutritional science. It is education, not a promise that a roller will treat a medical condition.
We don’t claim the Roller cures insomnia, anxiety, or cramps. Brands that do are usually overstepping the line. What we offer is a clean, single-active, daily magnesium ritual formulated to be gentle on the most sensitive skin and suitable to use during pregnancy.
If you have a medical condition, are pregnant or breastfeeding, or take prescription medication, speak to your healthcare provider before adding any new product — including this one.
