Form and source: Zechstein magnesium chloride flakes are free from additives and are designed for skin absorption when used in baths or foot soaks.

What Does Magnesium Chloride Do?

Magnesium supports normal muscle function and helps skin barrier function as part of healthy skin maintenance. This aligns with EFSA guidance that magnesium is a nutrient involved in everyday physiological processes. Research suggests topical magnesium baths can raise magnesium levels and promote relaxation.

This suggests that skin absorption can influence mineral status and contribute to relaxation and hydration.
