Our flakes are ideal for transdermal magnesium use (absorbed through the skin) by adding to bath or foot spa or by diluting in water to make an oil that can be applied to the skin. This is fast growing in popularity as a means of increasing body magnesium levels without the drawbacks (and side-effects) of consuming magnesium supplements.
Our Magnesium Chloride Flakes are from one of the most renowned and pure sources in the world, The Dead Sea.
While there are other sources even more pure than these (such as underground sources like the Zechstein sea), these are often much more expensive for comparatively little difference in the product. (Compare the specifications below to see ours are already very pure). However, there are some sources of magnesium flakes to avoid, such as those from salts lakes in come parts of the USA. These have been found to be polluted with many times the permissible level of Mercury and other toxins.
Q) It says not for internal use, why not?
A) We do not recommend taking magnesium salts internally as they can cause stomach upset. Transdermal application (through the skin) is well proven and established for boosting magnesium levels and we have experienced this personally ourselves.
