Elektra Magnesium Creams are another opportunity for the body to absorb magnesium via the skin. Just as the body absorbs vitamin D3 from the epidermis as required ( after making it from direct sunlight exposure ) magnesium is also absorbed into the epidermis via magnesium flakes hot water soaking, Magnesium Cream Moisturizer or Magnesium Oil Spritz topical application. 

The body will absorb as much as it needs to achieve homeostasis. When saturation is reached it stops absorbing at that time. Magnesium is constantly used in the tissue cells ( skin, muscle, bone, hair etc ) and needs to be replenished on a daily basis.
