How is Karma Rub different to other magnesium companies.

Karma Rub Liquid Magnesium is entirely 100% natural and comes directly from our family's farm in Victoria, Australia. We call it Liquid Magnesium as it has a high percentage of magnesium chloride 45% within it, 5% magnesium sulfate, the remainder of Karma Rub Liquid Magnesium is naturally occurring trace minerals such as zinc, copper, potassium, calcium. We add lemon myrtle oil or lavender oil for scent purposes as Karma Rub Liquid Magnesium is extracted from the ground and would otherwise have an earthy smell when we bottle it. All our additional magnesium products, Sports Creams, Massage Creams and Night Creme's are developed with our own Karma Rub Liquid Magnesium within it; which is what stands us apart from every other magnesium company. We are not just a small family run business, but a true product of Australia and all Australian made.

Where does our magnesium come from?

Karma Rub's Liquid Magnesium comes directly to us in Melbourne from a family member's farm in Victoria, Australia. We call it Liquid Magnesium as it has a high percentage of magnesium chloride 45% within it, 5% magnesium sulfate, the remainder of Karma Rub Liquid Magnesium is naturally occurring trace minerals such as zinc, potassium, copper, calcium. We are not just small family run business, but a true product of Australia with all Australian made products. Other companies often source their magnesium chloride from overseas locations, meaning more middle supply chain steps before the product reaches shelves in Australia. It may be made in Australia, but it may not be truly Australian. Depending on the source of where the magnesium chloride comes from the mineral profile of the product may also differ & this is why you may experience differences between seemingly comparable products.

Is Karma Rub safe for children?

Children’s skin can be more sensitive than adult skin, so starting with a small amount helps minimise the chance of tingling or irritation.
With topical magnesium, more isn’t always better—a light application is usually enough for a comfortable meaningful experience.

How to use

  1. Patch test first (always): Apply a tiny amount to a small area (outer thigh or upper arm) and wait 24 hours to check for redness or irritation.
  2. Use a small amount: Start with 1–2 light sprays (or 2-3 drops of our liquid magnesium) into your hands, then rub in—rather than spraying directly onto the child.
  3. Apply to less-sensitive areas: Legs, feet, shoulders, or back are usually better than freshly shaved areas, face, or underarms.
  4. Avoid broken or irritated skin: Don’t use on cuts, eczema flare areas, rashes, or sunburn.
  5. Follow with moisturiser if needed: If your child has dry or sensitive skin, applying a gentle moisturiser after can improve comfort. Or try one of our creams.
  6. Supervise and wash hands: Make sure it doesn’t get into the eyes or mouth.

Normal: A mild tingle or warmth can happen, especially on dry skin.
Not normal: Persistent stinging, redness, hives, or discomfort—rinse off with water and discontinue use.

How often can it be used?

  • Begin with 2–3 times per week, then increase gradually if the child’s skin tolerates it well.
  • Many families keep to small daily use or a few times weekly, depending on sensitivity.

Important safety note

Karma Rub Liquid Magnesium is for external use only. If your child is very young, has highly sensitive skin, or you have any concerns, it’s best to check with a healthcare professional first.

Magnesium

What is Magnesium?

Magnesium is an essential mineral your body needs every day to support normal functions like muscle and nerve activity, energy production and overall cellular balance. Magnesium is responsible for over 300 enzymatic functions within your body. It’s naturally found in foods such as leafy greens, nuts, seeds, legumes and whole grains. Many people choose to include magnesium in their daily routine to ensure wellbeing and overall healthy lifestyle maintenance.

What does magnesium do in the body?

  • Energy production (ATP): Magnesium helps your body turn food into usable energy. It also helps “activate” ATP (your cells’ energy currency), so energy processes can run normally.
  • Muscle function: Magnesium supports normal muscle contraction and relaxation by helping regulate how minerals like calcium move in and out of cells.
  • Nervous system support: It helps with normal nerve signalling and communication between cells—part of why people associate magnesium with feeling “more balanced.”
  • Electrolyte balance & hydration: Magnesium works alongside other electrolytes to help maintain fluid balance and normal cellular function.
  • Bone and structural health: A significant portion of the body’s magnesium is stored in bone, where it plays a role in normal bone structure and mineral metabolism.

Protein and DNA/RNA processes: Magnesium is involved in building proteins and supporting normal cellular growth and repair processes.

What are the benefits of magnesium for everyday wellness?

Magnesium is an essential mineral involved in hundreds of processes in the body, including supporting normal muscle function, nerve signalling and energy production. Many people include magnesium in their routine to help maintain a sense of balance, support everyday energy resilience and promote relaxation —especially during busy or demanding periods. It’s a simple, foundational nutrient that fits well into daily wellbeing habits alongside good sleep, movement, and hydration. Magnesium supplementation is often required as we typically don't have enough naturally present in our daily diet.

What are common signs you may be low in magnesium?

Magnesium supports over 300 enzymatic processes in the body, so when levels are low, people may notice general signs of feeling run down, poor sleep, muscle tightness or twitching, or feeling more tense/stiff than usual. Some people also report low energy, headaches, or difficulty winding down after a big day. 

Why people choose to supplement magnesium

Even though magnesium is found in foods (leafy greens, nuts, seeds, legumes, wholegrains), people often don’t consistently reach ideal intake. Common reasons include:

  • Modern diets skew lower in magnesium-rich whole foods and higher in processed foods.
  • Busy lifestyles and higher demands (stress, intense training, sweating, irregular sleep) can make people feel like they benefit from extra magnesium support in their routine.

Digestive tolerance: Some people don’t love how oral magnesium feels in their stomach at higher doses, so they explore different formats or lower, more consistent intake.

What is the difference between oral and topical magnesium

Oral magnesium is swallowed and absorbed through the digestive system, so it’s often chosen by people looking to increase dietary magnesium intake — but it can vary in tolerance depending on the form and dose and some people experience digestive upset.

Topical magnesium is applied to the skin, making it a simple “rub-on” option that fits into a body-care routine and allows for targeted application to areas like legs, shoulders, or back—without involving the stomach and or causing any digestive upset, while receiving direct application benefits.

What foods are high in magnesium (and why do people still fall short)?

Magnesium is found in many everyday foods like leafy greens (spinach), nuts and seeds (pumpkin seeds, almonds), legumes (black beans, lentils), whole grains, avocado, bananas, and dark chocolate. Even with a “fairly healthy” diet, people can still fall short because modern eating patterns often include more processed foods.

Some farming/food processing methods can reduce the natural mineral content we would otherwise ingest if foods were organically farmed.

Busy lifestyles, high stress and higher activity levels can also increase the body’s demand for magnesium.

Topical Magnesium 

How long does topical magnesium take to work (and what should you expect to feel)?

Everyone’s experience is different — some people notice a difference in feeling less tight or stiff right away after application, while others simply enjoy how it feels as part of their daily routine, building up magnesium stores so they're less likely to become physically fatigued and experience delayed onset muscle soreness. For best results, use it consistently and pay attention to what amount and timing feels best for your body.

Can topically applied magnesium produce a laxative effect like oral magnesium supplements?

No, generally using topical magnesium is well tolerated by people who have digestive issues and those who experience a laxative effect when ingesting oral magnesium. This is why topical magnesium is great option to be used daily, as skin can naturally self-regulate the absorption of minerals, leaving you with the amount of magnesium your body actually needs.

Why can oral magnesium supplements be difficult to absorb?

Oral magnesium supplements can be challenging for some people to digest as different forms of magnesium vary in how well they dissolve and are absorbed in the digestive tract.

Absorption can also be influenced by factors like gut health, taking it alongside certain foods or medications. Larger doses may be more likely to cause digestive discomfort, which can limit how consistently someone can take it, and how much they can absorb.

Does topical magnesium absorb through the skin, how does it work?

Topical magnesium works well because hair follicles and sweat ducts act like small “entry points". Topical magnesium can be applied right where you want it or need it physically—directly onto the skin—making it an easy, targeted part of a daily body-care routine. It also gives many people a gentler alternative to swallowing oral magnesium supplements, especially if they’re sensitive to oral magnesium or prefer a simple ritual after showering, post exercise or wind down bedtime routine.

Why can topical magnesium tingle or feel itchy, and how can you prevent it?

A mild tingle can happen for some people, especially on freshly shaved skin, very dry skin, or if you apply too much at once. To reduce this, apply to clean, dry skin, start with a small amount, avoid broken/irritated areas and follow with a moisturiser if your skin is sensitive or wash off after several minutes once the magnesium is absorbed.

Can you use topical magnesium every day, and how much should you apply?

Topical magnesium is commonly used daily. Most people prefer to start small and build up, based on comfort. A good rule of thumb is to begin with a light layer on areas like legs, shoulders, or back, then adjust the amount as needed. A good time to use topical magnesium is on the soles of your feet prior to bed. Try it once and feel the difference.

Can you use topical magnesium while pregnant or breastfeeding?

If you’re pregnant or breastfeeding, it’s best to check with your healthcare professional before adding new products to your routine, even body-care products. If you do use it, start with a patch test first and avoid applying to sensitive or broken skin.
