Dead Sea Salt

Dead Sea Salt is a mineral-rich crystalline compound with a distinct ionic composition markedly different from ocean salt. Primary macrominerals: Magnesium (Mg²⁺) at approximately 30,000–50,000 mg/kg — the dominant mineral, present largely as magnesium chloride (MgCl₂); Potassium (K⁺) at approximately 20,000–40,000 mg/kg, primarily as potassium chloride (KCl); Calcium (Ca²⁺) at approximately 1,600–2,000 mg/kg, present as calcium chloride (CaCl₂); Sodium (Na⁺) at approximately 30,000–80,000 mg/kg as sodium chloride (NaCl) — notably lower (~12–18% NaCl) compared to ocean salt (~97% NaCl). Trace minerals include Bromine (Br⁻) at approximately 5,000–10,000 mg/kg as bromides, which contribute to its sedative and anti-inflammatory skin properties; Sulfur compounds at approximately 400–800 mg/kg; Zinc (Zn²⁺) at approximately 50–100 mg/kg; Strontium (Sr²⁺) at approximately 30–60 mg/kg; Iron (Fe) at trace levels (~10–20 mg/kg); Manganese (Mn) at approximately 5–15 mg/kg. Bioavailability notes: Dead Sea Salt is used exclusively as a topical/external agent, not for dietary consumption. Transdermal absorption of magnesium ions through skin bathing is documented, though absorption rate is debated — estimated at 1–5 mg/cm²/hour under prolonged immersion. Bromide ions are notably bioavailable transdermally. It contains no macronutrients (zero protein, fat, carbohydrates, or dietary fiber), no vitamins, and no caloric value. The unusually high magnesium-to-sodium ratio is the defining characteristic distinguishing it from common sea salts.
