Magnesium Sulphate (Epsom Salts) vs Magnesium Chloride Flakes – What’s the Difference?
Share
Magnesium is an essential mineral for muscle relaxation, nerve function, and overall well-being. Two popular ways to supplement magnesium externally are Epsom salts (magnesium sulphate) and magnesium chloride flakes. While both are commonly used in baths, skincare, and wellness, they have distinct properties that make them suited to different purposes.
Epsom Salts (Magnesium Sulphate)
Epsom salts are magnesium sulphate crystals, widely used for muscle relaxation, stress relief, and skincare. When dissolved in warm water, they can:
- Soothe sore muscles and joints – Ideal for post-exercise recovery.
- Promote relaxation – Magnesium absorption through the skin may help reduce stress and support restful sleep.
- Exfoliate and soften skin – Used in scrubs or foot soaks to remove dead skin and improve texture.
- Support plant health – Epsom salts can be added to garden soil to provide magnesium for stronger plant growth.
Magnesium Chloride Flakes
Magnesium chloride flakes are more easily absorbed by the body, making them a preferred choice for topical magnesium supplementation. They are commonly used for:
- Deeper muscle relaxation – Due to better absorption, they are often recommended for those with magnesium deficiencies.
- Targeted pain relief – Frequently used in magnesium oil sprays for localised application.
- Sports therapy and recovery – Athletes use magnesium chloride in baths to reduce muscle cramps and fatigue.
- Foot soaks – Help relieve swelling, soothe tired feet, and support circulation.
- Eco-friendly de-icing – Magnesium chloride melts ice effectively with less environmental impact than traditional salts.
Which One Should You Choose?
- For general relaxation, muscle recovery, and occasional baths – Epsom salts are an excellent option.
- For regular magnesium supplementation and deeper absorption – Magnesium chloride flakes offer superior bioavailability.
- For skincare or sports therapy – Magnesium chloride works well in topical sprays, while Epsom salts are great for exfoliation.
