The Best Magnesium Oil: Our Picks

Guide: Questions you should ask yourself before buying magnesium oil

What is magnesium and why is magnesium important for my body?

If you have a magnesium deficiency, you get muscle cramps and feel tired. You can prevent these symptoms by eating a diet rich in vegetables and whole grains.

You will find a particularly large amount of magnesium in wheat bran, which contains about 550 mg of magnesium per 100 g. There are also pumpkin seeds that are rich in magnesium. There are also pumpkin seeds rich in magnesium with approx. 535 g magnesium/100 g or sunflower seeds with approx. 420 mg magnesium/100 g (Image source: / chuttersnap).

The problem with dietary supplements that contain magnesium is that they are often overdosed.

Magnesium supports the regulation of your energy metabolism, muscle and nerve functions.

However, malfunctions of your muscles and nerves are rarely due to a magnesium deficiency, because magnesium deficiency rarely exists.

Magnesium deficiency is often not as easy to diagnose as other deficiencies. There are various tests to detect the amount of ionising magnesium in the blood or urine. These are considered relatively reliable.

Basically, the body contains between 21 and 28 g of magnesium. However, the proportion in the blood reflects only about one per cent of the total amount. The largest proportion is contained in muscles, bones and soft tissue.

As a result, it can happen that everything seems normal in the blood, but there is nevertheless a severe magnesium deficiency. A magnesium content of 0.75-1.05 mmol/L in the blood serum is considered good.

A clear deficiency is when the magnesium concentration is below 0.61 mmol/L, while a mild deficiency is diagnosed at below 0.75 mmol/L. In the case of a magnesium deficiency, doctors speak of hypomagnesemia. (1)

Magnesium is vital for your body and is involved in various enzyme systems.

Muscle cramps and pain can have many causes. So you don't have to fear a magnesium deficiency right away.

What is magnesium oil and what can I use it for?

Magnesium oil consists of magnesium chloride and purified water. It is called oil because of its oily consistency.

In reality, however, it is not an oil. In addition, magnesium oil does not have any properties that are typical of an oil. Magnesium oil is mainly sold as a spray or as a solution in canisters

Area of application Effect
Dental health Supports the build-up of tooth enamel
Mental problems No effect because magnesium does not penetrate through the skullcap
Cardiovascular diseases and palpitations Magnesium oil is useless here, oral or intravenous magnesium supplements should be taken instead
Cluster headaches and migraines No healing effect, useless, instead one should breathe pure oxygen
Premenstrual syndrome and menopausal symptoms magnesium oil has no effect here, instead the hemp extract CBD should be used
Constipation magnesium oil is useless here, instead sauerkraut juice helps
Sports Less pain due to placebo effect, cooling spray relieves pain

It is worth mentioning among the areas of application of magnesium oil that it only helps with dental health problems and after sports activities. However, magnesium oil does not help in such ways to the extent that it is really worthwhile.

Bone health

About 60% of the magnesium stored in the body is found in bound form in the bones. It actively participates in an exchange between the bones and the blood serum.

The lifestyle and especially the diet in western countries can lead to an over-acidification of the body and to a disturbance of the bone mineralisation.

A meta-analysis was conducted on the topic of bone health and magnesium, which looked at 12 case-control studies. A link was found between reduced blood magnesium levels in post-menopausal women and osteoporosis. (2)

Heart attack

It is interesting to see whether a magnesium deficiency could also provoke a heart attack. In fact, it is thought that lowered magnesium blood levels may be associated with an increased risk of myocardial infarction.

This is because magnesium is significantly involved in the relaxation and dilation of the coronary arteries. Constriction or total occlusion can therefore lead to cardiac arrest. (3)

High blood pressure

Magnesium is said to have a blood pressure-lowering effect by promoting the relaxation of the smooth vascular muscles. This is most likely due to a balancing of the calcium concentration in the muscle cells, which is converted by magnesium.

Magnesium influences the release of nitric oxide, which in turn triggers the blood vessels and the lowering of blood pressure. (4)

Where should I apply magnesium oil?

You can easily apply the magnesium oil to the desired areas of the body and massage it in.

The oil should not come into contact with eyes, mucous membranes and open wounds because magnesium chloride is a mineral salt that can cause an unpleasant burning sensation.

Furthermore, you should not spray magnesium oil on freshly shaved areas. To make sure that nothing gets into your eyes after application, you should wash your hands thoroughly.

How should I dose magnesium oil and how often should I use it?

Usually 3 to 5 sprays on the skin are enough. You should be a little sparing with the oil at first.

Then you should slowly increase the dose. The reason for this is that your skin has to get used to the magnesium oil.

Later on, you do not need to worry. Side effects are unlikely to occur. You can therefore adjust the dose according to your individual needs.

More than 20 sprays a day is basically a waste. For high needs, stick to 15-20 sprays. An exact dosage is not necessary.

What application errors and side effects of magnesium oil do I have to consider?

In principle, magnesium oil is not dangerous, especially as there is no exact dosage. However, bear in mind that side effects may occur under certain circumstances.

By applying the magnesium oil to the skin, you avoid the gastrointestinal tract and thus reduce the risk of side effects.

However, please note that side effects may occur if you do not use the magnesium oil correctly. Therefore, you should consider the following:

  • The skin of small children is still very thin and therefore sensitive to irritation. Therefore, you should not "supply" your children with magnesium oil, unless you let your children enjoy a one-percent concentrated magnesium bath, provided they do not have any skin problems.
  • You should not apply magnesium oil to skin areas where you have already applied body lotion or other body oils.
  • After shaving, wait 24 hours before applying magnesium oil to the shaved area. Otherwise, your skin may redden. If you accidentally get magnesium oil on the shaved area, you should rinse the affected area with water.
  • You should also keep genitals and nipples away from magnesium oil, as it can sting unpleasantly.

How do I prepare a magnesium bath?

A magnesium bath is almost as simple as simply applying magnesium oil.

In order to conjure up not only magnesium-containing foot baths but also full baths, you need magnesium flakes or magnesium chloride hexahydrate powder for the preparation.

The magnesium content of both products is identical at 11.95 %. Therefore, you can dose both with the same amount.

Bathe your feet for 20-30 minutes. You should also stay in a full bath for this long (Image source: / Jared Rice).

For the bath, simply pour magnesium chloride into a bowl or directly into the bathtub and stir occasionally. When the magnesium chloride is completely dissolved, the bath is ready.

For a foot bath, you can use a foot tub. Pour magnesium chloride hexahydrate into it. The following solution concentrations are recommended:

  • 3 % solution: 250 g in 4 litres of water (37 °C)
  • 4 % solution: 350 g in 4 litres of water (37 °C)
  • 5 % solution: 425 g in 4 litres of water (37 °C)

For a full bath, we recommend a one percent solution at a water temperature of 37°C.

Simply add 1000 g of magnesium chloride to 50 litres of warm water or 750 g to 37.5 litres of warm water. Your entire body should be in the water.

Is magnesium oil suitable as a mouthwash?

Magnesium oil can be used as a mouthwash. As mentioned above, the oil has positive effects on our teeth. You can add 1 to 2 ml to 20 ml of water. You can then rinse your mouth with this mixture for one minute.

Alternatively, instead of using toothpaste, you can put 5 to 7 drops of magnesium oil on your toothbrush and brush your teeth as usual.

This will help prevent gingivitis, freshen your breath and generally improve your dental health.

What is the shelf life of magnesium oil?

The expiry date can vary depending on the magnesium chloride. As a rule, the oil expires after 36 months.

How much does magnesium oil cost?

The price of magnesium oil varies between €10 and €30 per pack, depending on the supplier, with one pack containing 1000 ml.

What are the alternatives to magnesium oil?

You can easily cover your magnesium needs with food.

A delicious source of magnesium is chocolate or cocoa. Deoiled cocoa powder contains 400 milligrams of magnesium per 100 grams. Dark chocolate contains the same amount, but 149 milligrams.

In the following we show you a table of foods rich in magnesium.

Foodstuffs magnesium content in mg per 100 g
Amaranth 308
Quinoa 276
Wheat germ 250
Wheat bran 590
Cashews 292
Chia seeds 335
Pumpkin seeds 402
flaxseeds 350
poppy seeds 333
pine nuts 235
sesame seeds 347
sunflower seeds 395
lima beans 216
soybeans 220
dried bananas 110

So you can see that nuts, seeds and cereal products are among the biggest sources of magnesium.

In addition to natural sources of magnesium, there are also a number of dietary supplements. However, these are often overdosed and can lead to health problems if taken over a long period of time.

The following dietary supplements are available

  • Tablets
  • Capsules
  • Magnesium citrate in a bag with granules
  • Magnesium sticks
  • Effervescent tablets
  • Magnesium-Taler
  • Powder
  • and magnesium dragées

Decision: What types of magnesium oil are there and which is right for you?

If you want to get yourself a magnesium oil, there are two main options to choose between:

  • Pure magnesium oil
  • Magnesium oil with DMSO

The different types each come with advantages and disadvantages. Depending on what you prefer, a different type will be suitable for you. The following section will help you decide.

What distinguishes pure magnesium oil and what are the advantages and disadvantages?

No extra substances are added to pure magnesium oil. It is therefore pure magnesium chloride. Many people report a pain-relieving effect, be it in relation to back pain, neck pain or other pain, especially muscle tension.

  • Pure magnesium chloride
  • deposited protected from environmental pollution
  • odourless
  • not chemically treated
  • good for relaxation massages
  • Harmful to eyes, wounds and freshly shaved areas as soon as it comes into contact with them
  • No scientific studies to confirm positive effects

What distinguishes magnesium oil with DMSO and what are the advantages and disadvantages?

Magnesium oil with DMSO is available in a set. This means that high quality magnesium chloride is mixed with DMSO in water so that it can promote the regeneration of joints, muscles and bones.

It also supports the normal reorganisation and revitalisation of cells in cases of severe tissue damage.

Dimethyl sulphoxide is generally used for the external treatment of pain, inflammation and swelling. In combination with magnesium oil, it has an anti-inflammatory, analgesic, vasodilator and wound-healing effect.

In addition, DMSO increases the absorption of pharmaceutical substances, i.e. pharmacologically active substances of drugs are better absorbed.

  • Supports muscles and joints
  • regenerative effect
  • counteracts tension
  • more pain-relieving than pure magnesium oil
  • anti-inflammatory, antioxidant, vasodilator, wound-healing and antimicrobial
  • Damaging effect on clothing and plastics
  • allergic (skin) reactions
  • unpleasant mouth and body odour as well as digestive disorders

We recommend a combination of magnesium oil and DMSO. DMSO actually increases the absorption of other substances into the skin. However, it is questionable whether magnesium is better absorbed by the skin.

Buying criteria: These are the factors you can use to compare and evaluate magnesium oils

In the following we would like to show you which factors you can use to compare and evaluate magnesium oils. This will make it easier for you to decide whether a particular magnesium oil is suitable for you or not.

In summary, these are:

  • Dosage form
  • Money-back guarantee
  • Additives
  • Dosage

Dosage form

The products are not all put into the same bottles. Some come in PET bottles, others in glass bottles. What you should look for is a spray head. It makes the application easier.

An opaque amber glass bottle also increases the overall quality of the product, because it prevents UV rays from penetrating the product. In addition, the bottle cap should be specially coated so that no particles can be loosened by the DMSO.

Money-back guarantee

Due to the lack of scientific confirmation of the manufacturer's promises, you should pay attention to a money-back guarantee.

The product may not actually work for you, even if other users are enthusiastic. The time limit for returning the product is usually 30 days, which is reasonable.


Make sure that the product does not contain any additives. These can cause allergies or other side effects. Dyes are an unnecessary burden on your health. Magnesium oil with DMSO


If the oil has a low dosage, you will have to increase the dose so that the pack is used up more quickly. It makes more sense to use a more concentrated solution.

You can mix magnesium oil with water in the beginning. Later, when you increase the dose, it is no longer so "complicated" to adjust the dose.

Facts worth knowing about magnesium oil

Why does magnesium oil burn and itch?

There are various reasons for the stinging sensation on the skin when you apply magnesium oil. In most cases, it is not due to the sensitivity of the skin. Rather, it is combinations of several factors that promote such itching. Potential reasons are the following:

  • A low magnesium level increases itching on the skin. The less magnesium in the body, the more severe the itching.
  • The amount of magnesium oil applied can make itching more severe if you overdo it with the dose the first time. Instead, let your skin get used to the oil slowly and you will notice how the itching gets less and less each time.
  • By relaxing the muscle cells and increasing the blood flow in the capillaries, the finest branches of the blood vessels, a burning sensation can occur.
  • An itching sensation in sensitive skin can also be a sign that the oil is being absorbed by the skin.

How should magnesium oil be assessed from a scientific point of view?

For example, the University of Edinburgh and the University of Cambridge have done research on whether there is a connection between magnesium deficiency and sleep disorders.

They actually found out that magnesium oil can be used for sleep disorders.

However, they did not provide any scientific evidence. So you can't follow their research on magnesium oil.

So far, there is not a single official study that confirms the effects of magnesium oil promised by manufacturers.

Even the manufacturers do not provide any tangible evidence of what they promise with their products.

All studies on magnesium oil are either unofficial and have too few participants or without the inclusion of control groups and medical experts. Moreover, all participants know that magnesium oil is actually being tested and not a placebo.

In this respect, the reliability of such studies is lacking. Even Stiftung Warentest contradicts the promise that magnesium oil can be absorbed through the skin.

In addition, Siftung Warentest could not find any clear evidence of possible effects of the oil.
