Magnesium is for all round health. After oxygen, water, and basic food, magnesium may be the most important element needed by our bodies, vitally important yet hardly known. It is more important than calcium, potassium or sodium and regulates all three of them. Millions suffer daily from magnesium deficiency without even knowing it. Koa Organics uses pure magnesium chloride in its skincare products which are topically applied for fast absorption into your bloodstream, cells and tissues that need it most.
