    The Magnesium Tingle

This will pass with regular use and as absorption commences immediately, skin can be towelled off after massaging in.

  • FAQs
      Can I use transdermal magnesium during pregnancy?

      Transdermal magnesium is perfectly safe to use during pregnancy with no restrictions on dosage levels during this time.

      However, it is important that during pregnancy you avoid essential oils. Magnesium Oil Joint Spray, Magnesium Oil Recovery Spray and Magnesium Oil Goodnight Spray all contain essential oils.

      All our other Magnesium products are suitable during pregnancy and breastfeeding, with a full list of suitable products being found here.

      I take medication, are there any contraindications?

      There are no contraindications with any of our transdermal magnesium products.

      What is the source of the magnesium chloride hexahydrate?

      The magnesium chloride we use is a solution mined in Veendam in the Netherlands. It is mined from an ancient seabed that has been condensed and purified for over 250 million years. To mine the magnesium chloride, spring water is carefully pumped down to dissolve the seam and the solution is brought up to the surface. The magnesium chloride concentration is 31%, perfectly stable to avoid recrystalising. This solution is the foundation of our Magnesium Oil sprays and Magnesium Soak. Nothing is added to it to keep the spray as pure and as universally acceptable as possible.

      Can I overdose on transdermal magnesium?

      You do not need to worry about overdosing when using transdermal magnesium. Upper limits are only set when using the product orally, as large doses can have a laxative effect due to it being a natural relaxant.

      Toxic symptoms from increased magnesium intake are not common as the body eliminates excess amounts, unless there are serious problems with kidney function.

      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.
