@GRay high absorption from gut to blood is different than from blood to tissues and cells
magnesium chloride oil 600mg per teaspoon, one teaspoon
2tbsp coconut oil
4-8 drops essential oil of your choice
mix together in bowl, apply all over body after shower or bath . let dry 10-15 min before clothes on.
i think this absorbs slower and therefore is like dosing small amounts frequently orally
