I want to clarify one thing: there is NO â€œoilâ€ in what is being commonly referred to as â€œmagnesium oil.â€ In fact, there are no additives whatsoever. This solution is formed via a process of extraction. Starting with sea water, the water, or H2O, is removed via evaporation from sun exposure. As the water is removed, sodium binds with chloride, forming salt crystals (NaCl). Magnesium, the next most abundant component, also binds with chloride, but it takes a thick, liquid form, referred to as a brine. This brine has the consistency of a light oil, but is not an oil. It is pure nutrition. Besides magnesium, this solution includes copper, traces of sodium, iron, manganese, calcium, nickel, potassium, selenium, zinc, and others. If that werenâ€™t important enough, these minerals are present in the best proportion to benefit our cell physiology.
