Solubility: Complexed with humic/fulvic acids in peat
Concentration in peat: 100–5000 ppm, higher in lowland peat
Magnesium is a mineral present in peat, more abundant in lowland (fen) peat than sphagnum bog peat due to groundwater mineral input. It is essential for over 300 enzymatic reactions in the body and plays roles in muscle relaxation, nerve function, and inflammatory regulation.
Cosmetic Relevance
Magnesium’s primary relevance in peat applications is its muscle-relaxing and calming properties in balneotherapy. Transdermal magnesium absorption during peat baths may contribute to the relaxation and stress-relief effects reported by patients. In topical applications, magnesium contributes to skin barrier function.
