Magnesium Foot Bath: Dosage, Instructions and Benefits
Add about 100 ml of magnesium oil to 4–5 litres of body-warm water and soak your feet in it for 20–30 minutes. A magnesium foot bath is one of the simplest rituals for tired feet and heavy legs: the magnesium works directly through the skin, the warmth relaxes you, and after a long day you can really feel yourself unwind.
Whether after running, cycling, a long shift on your feet or simply in the evening before bed – here you’ll find out how to dose your foot bath correctly, what it does for you and how to build it into your routine.

Dosage and step by step
The standard recipe is: about 100 ml of magnesium oil to 4–5 litres of body-warm water, then soak your feet. Magnesium oil isn’t a plant oil, by the way, but a concentrated solution of water and magnesium chloride. The name describes the slightly oily feel on the skin, not any fat content.
Body-warm water, 20–30 minutes of soaking and at most around 4% magnesium chloride: these are the practical guideline values for a magnesium foot bath given by the German pharmacy news site Apotheke Adhoc (in German).
Guideline values for a magnesium foot bath
| Component | Guideline | Note |
|---|---|---|
| Magnesium oil | about 100 ml | Per foot bath; a concentrate of water and magnesium chloride |
| Water | 4–5 litres | Use a foot basin or bucket that fits both feet |
| Water temperature | body-warm, not hot | Pleasantly warm is most relaxing |
| Soaking time | 20–30 minutes | Finish earlier if your skin reacts |
| Magnesium chloride in the bath | at most around 4% | The standard recipe is well below this |
| Frequency | 2–3 times a week, or more often if you like | Ideal as a regular evening routine |
With a starting solution of 31% magnesium chloride, the standard recipe works out at under 1% magnesium chloride in the bath – pleasantly mild and still rich in magnesium. If you prefer it more intense, you can increase the amount of magnesium oil a little, as long as your skin feels comfortable.
How to prepare the bath
- Set up the basin. Use a clean foot basin or a sufficiently wide bucket. Place it so it can’t tip over and keep a towel within reach.
- Mix the water and magnesium oil. Pour in the water first, then stir in the concentrate evenly. The magnesium chloride is already dissolved in the magnesium oil, so there’s nothing solid to dissolve.
- Check the temperature. Test the water with your hand before putting your feet in. It should be pleasantly body-warm, not as hot as possible.
- Lean back. Set a timer for 20–30 minutes, read, listen to music or simply close your eyes.
- Dry carefully. Dry thoroughly between your toes as well.
- Rinse if you like. If your skin feels a little sticky, rinse it with clear water and dry it again.
For your first try, you don’t need any extra bath additives or a complicated mixture – water and magnesium oil are all it takes.
When to skip or stop the foot bath
Freshly shaved skin isn’t a good starting point for a magnesium foot bath. Wait until it has calmed down. Cracked heels, open blisters and other broken skin are also reasons to postpone the bath.
A slight tingling is normal, especially the first few times, and usually fades once your skin gets used to the magnesium. Strong burning, on the other hand, is not something you should put up with.
Situations and what to do
| Situation | What to do | Why |
|---|---|---|
| Freshly shaved skin | Don’t bathe until your skin has calmed down | Magnesium chloride can cause burning and redness there |
| Open areas, cracks or wounds | Wait until the skin has closed | Broken skin reacts more sensitively |
| First use with sensitive skin | Start with a shorter soak or less magnesium oil | Your skin gets used to the magnesium gradually |
| Burning or redness during the bath | Stop immediately and rinse with clear water | Start with less magnesium oil next time |
| Children or existing medical conditions | Ask a doctor or pharmacist first | Take individual circumstances and children’s sensitive skin into account |
Stop rule: A slight tingling is normal, burning and redness are not. If that happens, simply rinse off and start with a more diluted bath next time.

What a magnesium foot bath does for you
A magnesium foot bath combines two things: magnesium directly through the skin and a soothing warm soak. That’s exactly why it has been one of the most popular magnesium oil rituals for years – among athletes as much as anyone who ends the day with heavy, tired legs.
The benefits at a glance
- Relaxation for feet and legs: After running, hiking or a long working day on your feet, your feet and calves feel light again.
- An evening ritual to wind down: 20–30 minutes of warm water and quiet help you leave the day behind – ideal before bed.
- For muscles after sport: Many people use the foot bath after training for relaxed calves and to ease that heavy-legs feeling.
- Magnesium without tablets: No swallowing, no upset stomach – the magnesium comes in through the skin.
- Supple skin: Many people love the velvety feel of their feet after the bath.
How much magnesium is in a foot bath
Our magnesium oil contains 105 mg of magnesium per ml. With 100 ml per foot bath, that’s around 10,500 mg of magnesium in the water – so your feet soak in a truly magnesium-rich solution of pure Zechstein magnesium chloride.

A foot bath instead of tablets: magnesium through the skin
Most people take magnesium as a tablet or effervescent powder. In high doses, though, that can upset your stomach. A magnesium foot bath is the pleasant alternative: you treat yourself to a break and supply your skin with magnesium at the same time – no swallowing required.
Of course, a foot bath doesn’t replace a balanced diet. The two complement each other well: magnesium-rich foods for everyday life, the foot bath as a feel-good ritual in the evening.
Magnesium requirements at a glance
| Group | DGE estimated value per day (German Nutrition Society) |
|---|---|
| Men aged 19 and over | 350 mg |
| Women aged 19 and over | 300 mg |
If you do a lot of sport, sweat heavily or are often under stress, your requirement is higher. These magnesium-rich foods give you ideas for your meals – and the foot bath is the relaxing addition.
Magnesium oil, spray or gel compared
Magnesium spray or oil is usually not a question of different ingredients: a spray contains the same magnesium chloride solution as a product labelled magnesium oil. The difference lies mainly in the spray head and the dosing.
A spray head is handy for individual areas of skin. For a foot bath, a larger amount is easier to measure out from the 1-litre bottle. A gel, on the other hand, stays exactly where you apply it to massage it in.
Forms of magnesium compared
| Form | Typical use | Practical tip |
|---|---|---|
| Magnesium oil in a bottle | Foot bath concentrate, massaging in | Easy to measure, ideal for a foot bath |
| Spray | Applying to legs, feet or body | Handy for larger areas and on the go |
| Gel | Rubbing in and massage | Doesn’t drip, ideal for neck, shoulders and calves |
| Flakes or bath salts | Full bath | Less practical for a foot bath alone; follow the dosage on the pack |
When using magnesium flakes, make sure the solid particles dissolve completely. With magnesium bath salts it’s worth checking the ingredients list, because not every product contains only magnesium chloride. Magnesium oil is already dissolved and ready to use straight away.
For magnesium spray for children, it makes sense to check with a doctor or pharmacist.
What else you can use magnesium oil for
What is magnesium oil good for? Besides the foot bath, you can spray it directly onto your skin and massage it in: on your calves and thighs after sport, on your neck and shoulders in the evening or on the soles of your feet before bed.
Massage it in gently
Spray 5–10 pumps onto the area and spread the magnesium oil with your palms. After about 20 minutes, you can wash off any residue if needed.
- After sport: A magnesium oil massage on your calves or shoulders rounds off your workout.
- In the evening: A few sprays after your shower as part of your evening routine help you wind down.
- On your feet: For many people, magnesium oil on the soles of the feet before bed is the quickest alternative to a foot bath.
How often should you use magnesium oil? Many people use it daily, for example in the evening after a shower. If you have sensitive skin, start with just a few sprays and build up slowly.
A few minutes for yourself, warm water and magnesium – a relaxing evening can be that simple.
Plan your first foot bath in three steps
To get started, you don’t need a fixed weekly plan. One deliberately prepared evening is enough to get to know the ritual – and love it.
- Choose a time and get everything ready. Pick a quiet evening and set out your foot basin, water, measuring jug, timer and towel.
- Check your skin. Look at your heels, between your toes and any pressure points. If you’ve just shaved or have any open areas, postpone the bath.
- Enjoy and repeat. Notice how your feet and legs feel afterwards – and make the foot bath your regular evening ritual.
