The Appeal of Topical Magnesium
While oral supplements are common, topical application of magnesium offers a unique pathway for absorption, bypassing the digestive system entirely. This approach is particularly beneficial for individuals who experience gastrointestinal discomfort from oral magnesium or those seeking targeted relief for muscle soreness or skin irritation. When dissolved in water, the magnesium compounds in soap release ions that can be absorbed through the skin's largest organ, providing a direct route to the body's cells. This method not only provides the mineral's benefits but also combines them with the cleansing action of a traditional soap bar.
Common Forms of Magnesium in Soap
Magnesium doesn't appear in soap as elemental magnesium but rather as a salt. The most common forms used in soap and other topical magnesium products are magnesium chloride and magnesium sulfate.
- Magnesium Chloride: Often sourced from ancient seabeds like the Zechstein Sea, magnesium chloride is known for its high bioavailability and is easily absorbed through the skin. It is considered superior for sustained, longer-lasting benefits and is generally gentler on the skin compared to magnesium sulfate. This form is used in products designed for enhanced skin health, promoting hydration and balancing the skin's barrier.
- Magnesium Sulfate (Epsom Salt): More commonly known as Epsom salt, magnesium sulfate is a traditional ingredient in bath soaks for its muscle-relaxing properties. While it provides temporary relief for muscle soreness, its absorption is less efficient, and the effects are shorter-lived compared to magnesium chloride. Some with sensitive skin may also find it slightly drying or irritating.

- Pacha Soap Co.: Pacha Soap Co. is another brand found on the EWG database with products containing magnesium sulfate, typically designed for soothing or exfoliating purposes.

Benefits of Using Magnesium Soap
Integrating a magnesium soap bar into your daily hygiene routine can offer a range of therapeutic benefits. While not a replacement for medical treatment, topical magnesium can support overall wellness.
- Relieves Muscle Soreness and Tension: Magnesium helps regulate muscle contraction and relaxation. Soaking in magnesium is a proven way to ease muscle cramps and stiffness, especially after intense physical activity.
- Promotes Relaxation and Stress Reduction: Magnesium plays a role in regulating neurotransmitters that calm the nervous system, such as GABA. A warm shower or bath with magnesium soap can be a simple relaxation technique to combat stress and anxiety.
- Supports Skin Health: Topical magnesium has anti-inflammatory properties, helps regulate oil and sebum production, and strengthens the skin barrier. Magnesium chloride, in particular, can be hydrating and beneficial for conditions like acne or eczema.
- Supports Sleep Quality: By promoting physical relaxation and calming the nervous system, magnesium can help create a sense of calm conducive to better sleep.
Making Your Own Magnesium Soap
For those who prefer a DIY approach, creating your own magnesium soap is a straightforward process, often using a pre-made glycerin base and Epsom salt. Here is a basic recipe:
- Melt glycerin soap base: Cut the soap base into small cubes and melt it in a microwave-safe bowl in 30-second intervals until fully liquid.
- Add magnesium and oils: For a standard bar, start with a half teaspoon of Epsom salt, a teaspoon of coconut oil, and a few drops of your preferred essential oil (lavender, rosemary, and frankincense are calming options).
- Combine and pour: Mix the ingredients thoroughly and pour the mixture into a silicone soap mold.
- Harden and enjoy: Allow the soap to cool and harden completely for at least one hour before removing it from the mold.
Choosing the Right Magnesium Soap
When selecting a magnesium soap, consider your primary wellness goal. If you want maximum absorption and skin benefits, a bar with magnesium chloride (like Health and Wisdom or Zechsal) is a good choice. If you're looking for affordable, temporary relief from muscle soreness after a workout, a product with Epsom salt may suffice. For those with sensitive skin, opting for a magnesium chloride formula is generally recommended, as it tends to be less irritating. Always read the ingredients list to verify the type of magnesium used and check for any potential allergens.
Conclusion: Integrating Magnesium Soap into Your Routine
Magnesium-infused soap bars offer a relaxing and effective way to topically supplement this essential mineral. Brands like Health and Wisdom, Bare Bar, and Zechsal provide distinct options, utilizing different forms of magnesium to target various needs, from muscle recovery to skin hydration. By understanding the differences between magnesium chloride and sulfate and considering your individual goals, you can choose the right product to enhance your wellness routine.
