A Truly Premium Therapeutic Bath Additive Each bag is 36 ounces of 100% pure magnesium chloride flakes, sourced directly from the Dead Sea. These flakes contain the highest concentration of magnesium chloride (47%) on the market. Scented options consist of organic essential oil(s). No toxic or endocrine disrupting chemicals of any kind. We recommend using 0.5 - 1 cup/soak, as the flakes are highly concentrated. Experience transdermal magnesium supplementation by bringing the "Salt Sea" to your bath at home.  How to Use Add 0.5 - 1 cup of flakes into your tub and let them dissolve. We recommend soaking in pleasantly warm, not excessively hot water. Extremely hot water causes the skin to sweat, which expels toxins and prevents the body from absorbing as much magnesium as possible. Soak for at least 20 minutes to maximize benefits. You may also soak your hands or feet in a smaller bucket if you prefer/cannot access a bath tub! Dead Sea Flakes vs. Epsom Salt One of the most effective ways to increase magnesium levels in your blood is absorption through the largest organ in the body- your skin. A common misconception is that epsom salt (magnesium sulfide) is the superior therapeutic bath additive. In reality, magnesium chloride flakes win. Why are they better? In simple terms, magnesium chloride can be more efficiently absorbed by our bodies.  Bioavailability When looking at the two compounds on a molecular level, you can discover why. Epsom salt: magnesium + sulfate (  MgSO₄) Dead Sea flakes: magnesium + chloride (MgCl2) The key difference between Magnesium Chloride (flakes) and Magnesium Sulphate (salts) is the rate of absorption within the body. Because it is wholly soluble, Magnesium Chloride can efficiently absorb when exposed to the skin. This high solubility is vital to allow the compounds to break their bonds and absorb effectively into the body. Ultimately, Magnesium Chloride can be more easily absorbed and utilized by the body, when compared to using Epsom Salts. While the appearance and application may be similar, the ‘unseen’ difference in absorption between Magnesium Chloride and Magnesium Sulphate is what really sets these two compounds apart.
