About Magnesium & Mineral Therapy

What is topical magnesium?

Topical magnesium refers to magnesium applied directly to the skin in the form of a spray, soak or cream.

At Mullum Minerals, we use magnesium chloride to support the body through daily ritual. Topical application offers localised exposure and is commonly used to support muscle relaxation, skin health and evening wind-down practices.

It is not a replacement for oral supplementation or medical care, but a gentle addition to daily self-care.

What does magnesium do in the body?

Magnesium is an essential mineral involved in hundreds of processes within the body. It plays a role in:

Muscle contraction and relaxation
Nervous system signalling
Energy production
Skin barrier function

Magnesium is particularly important during times of stress, as stress can increase magnesium demand.

Our products are designed to support mineral replenishment through consistent ritual use.

Why are so many people interested in magnesium?

Modern life can place high demands on the nervous system and muscles. Stress, sleep disruption and hormonal changes may increase interest in supportive minerals like magnesium.

While we do not diagnose or treat deficiency, many people choose to include magnesium in their daily routine as part of a broader wellbeing approach.

Is topical magnesium scientifically proven?

Magnesium itself is well studied and recognised as essential to human physiology.

Research into topical magnesium is still evolving. Some studies suggest potential localised effects, while large-scale clinical research is ongoing.

At Mullum Minerals, we remain transparent and conservative in our language. Our products are designed to support wellbeing, not to diagnose, treat or cure medical conditions.

About Magnesium Chloride

Why does Mullum Minerals use magnesium chloride?

Magnesium chloride is widely used in topical formulations because it dissolves easily in water and is suitable for use in sprays, bath soaks and creams.

It aligns with traditional mineral bathing practices and is well suited for external application.

What is Zechstein magnesium?

Zechstein magnesium refers to magnesium chloride sourced from the ancient Zechstein Sea, a unique geological formation that existed across what is now northwestern Europe around 250 million years ago. This inland sea left behind deep underground deposits of highly concentrated magnesium chloride — untouched by modern pollution and protected beneath layers of rock far from surface contaminants.

Today, this mineral is extracted near Veendam in the Netherlands, where magnesium-rich brine is accessed from deep underground and processed under strict quality controls. Zechstein Minerals uses a defined batch protocol to select, analyse and certify each production batch, ensuring authenticity and traceability before it becomes part of products like ours.

Zechstein magnesium chloride is valued in the wellness and bodycare community because of:

Ancient, protected source — far removed from modern environmental pollutants
High natural concentration of magnesium chloride in the brine
Minimal processing — the mineral is used in its naturally occurring form
Certified quality control — with documented procedures and batch verification

We choose Zechstein magnesium because it aligns with our commitment to purity, transparency and consistent sourcing.

Is your magnesium tested for purity?

Yes.

Our magnesium chloride is sourced from Zechstein Minerals, a supplier known for its stringent quality control processes.

Each batch undergoes a detailed Batch Protocol, where the magnesium is tested at multiple stages to ensure consistency and purity. Zechstein Minerals also operates under ISO-certified standards, supporting traceability and quality assurance.

If you would like further information regarding sourcing or documentation, we are always happy to provide more detail.

Product Use

How do I use magnesium spray?

Apply 5–10 sprays to clean skin and gently massage in.

Common areas include:

Legs
Shoulders
Lower back
Abdomen

Allow to absorb. You may leave it on or rinse after 20–30 minutes if preferred.

Many customers use magnesium spray as part of an evening ritual.

How often can I use magnesium spray?

Magnesium spray can be used daily.

Consistency is generally more supportive than intensity. Start slowly and increase frequency as your skin tolerates.

Why does magnesium tingle or itch?

A mild tingling or warming sensation can occur when first using magnesium chloride. This is common and generally temporary.

It may be reduced by:

Applying to damp skin
Using a smaller amount
Following with body cream
Rinsing after 20–30 minutes

If irritation persists, discontinue use.

Can I rinse magnesium off?

Yes. After allowing it to absorb for around 20–30 minutes, you may rinse and follow with moisturiser.

How do I use magnesium bath flakes?

Add approximately 1 cup to a warm bath and soak for 20 minutes.

For a foot soak, use 2–3 tablespoons in a basin of warm water.

Bathing can be incorporated weekly or as desired.

Is bath residue normal?

Some natural mineral residue may remain in the bath depending on water hardness and soak composition. Rinsing the bath after use is recommended.

Skin & Sensitivity

Can I use magnesium on sensitive skin?

If you have sensitive skin, begin with a small amount and patch test before full application.

Avoid applying to broken or freshly shaved skin.

Pairing magnesium with a moisturising cream can help reduce sensation.

Can magnesium be used on the face?

Our magnesium spray is formulated for body use. If applying to the face, avoid the eye area and patch test first.

Sleep & Nervous System

Does magnesium help with sleep?

Magnesium is involved in nervous system regulation and muscle relaxation. Many people choose to use magnesium as part of an evening wind-down ritual.

Our products are not sedatives and are not intended to treat sleep disorders. They are designed to support relaxation within a broader bedtime routine.

When should I apply magnesium for best results?

Evening application is popular, particularly:

After a warm shower or bath
30–60 minutes before bed
During gentle stretching or breathwork

Magnesium works best when used consistently.

Women’s Health

Can magnesium support menstrual comfort?

Magnesium plays a role in muscle relaxation. Some individuals choose to apply magnesium to the lower abdomen or legs during their cycle as part of comfort-focused care.

Our products are not intended to treat menstrual disorders.

Can I use magnesium during perimenopause or menopause?

Many women incorporate magnesium into their routine during hormonal transitions to support relaxation and muscle comfort.

If you have specific health concerns, we recommend consulting your healthcare provider.

Can I use magnesium if I have thyroid conditions?

If you have a diagnosed thyroid condition or are taking thyroid medication, we recommend discussing any new products — including topical magnesium — with your healthcare professional.

Magnesium is an essential mineral involved in many processes within the body, including energy production, muscle relaxation and nervous system regulation. During times of increased physiological demand — such as chronic stress or hormonal shifts — some individuals choose to incorporate magnesium into their daily routine as part of supportive self-care.

Topical magnesium is used externally and is not intended to replace prescribed treatment or medical advice. Mullum Minerals products are not intended to diagnose, treat, cure or manage thyroid disease.

If you are under medical supervision, always follow your practitioner’s guidance.

Safety

Is topical magnesium safe?

Topical magnesium is generally considered safe for external use when used as directed.

Do not apply to broken skin. Discontinue use if irritation occurs.

Can I use magnesium during pregnancy or breastfeeding?

If pregnant or breastfeeding, please consult your healthcare provider before introducing new products into your routine.

What if I have kidney conditions?

Magnesium levels in the body are regulated by the kidneys. If you have a diagnosed kidney condition or reduced kidney function, we recommend speaking with your healthcare professional before introducing magnesium products into your routine.

Topical magnesium is used externally and research into systemic absorption through the skin is still evolving. As a precaution, individuals with kidney conditions should seek medical advice prior to use.

Ritual & Philosophy

How often should I use magnesium products?

Daily, gentle use is recommended over occasional high use.

Magnesium works best when integrated into rhythm — after showers, before bed, or as part of weekly soaking rituals.

Can I use multiple magnesium products together?

Yes. Many customers layer:

Magnesium spray + body cream
Weekly bath soak + daily spray

Listen to your body and adjust accordingly.
