Transdermal Magnesium Chloride

Bathtub soak

More economical to use magnesium chloride flakes (not oil)  for this method

For a severe magnesium deficiency -  consider a relaxing soak in a magnesium chloride solution in the bathtub (and also add baking soda for an extra alkalizing touch).

It is counter-productive if your water is chlorinated - in which case you will need to use a filter at the supply. Chlorine filters can be found online.

How-to

How many pounds of magnesium chloride flakes? - use 2-4 pounds magnesium chloride flakes considering that the more you fill the tub, the more diluted your solution will be (seawater contains ~1300ppm  magnesium). Utilizing the principles of balneotherapy, enough magnesium chloride must be added to bath water to make a hypertonic solution (i.e bath has a higher salt concentration than the body). This is an excellent way to both deliver needed trace minerals directly into the body, and to help the body cleanse itself.

The temperature of the magnesium bath should be warm (101 -105°F, 37 - 40°C ) - rather than hot, for efficient absorption of the magnesium.

How long?  25-30 minutes is suggested; longer bath times can increase the amount of magnesium absorbed, but you don't want to be sitting in cold water;

How often?   For four weeks, take no more than 2 bathtub soaks per week. This is a powerful way to improve your magnesium levels, but be aware that you can have too much of a good thing. Too much magnesium becomes unbalanced with the body's calcium and can result in muscle weakness—take note of sensations while in the tub, or muscle weakness outside the tub. If this occurs take some good calcium to counteract the magnesium overdose.
