  • FAQs
      Is magnesium safe to take orally?

      Our Magnesium Flakes, Magnesium Oil Body Spray and Magnesium Sensitive sprays are all a pure concentration of magnesium chloride making them perfectly safe to ingest. The purity of our source means that these products are free from man-made pollutants and safe for human consumption.

      However, as magnesium is a natural relaxant, if you take a large dose orally it can have a laxative effect. Using it as a transdermal product means that it avoids processing by the digestive system and so too avoids the laxative effect; therefore you can take larger doses through the skin.

      What is the difference between the Magnesium Flakes and the Magnesium Soak?

      The key difference between Magnesium Soak and Magnesium Flakes is the concentration. Magnesium Soak contains magnesium chloride at 31% concentration while the Magnesium Flakes are at a concentration of 47%.

      Magnesium Flakes will provide a higher level of elemental magnesium when added to a bath than Magnesium Soak will. However, for those with skin conditions where the skin is broken Magnesium Soak provides a more gentle option.
