Natural mineral support for mucous membranes

Karlovy Vary salt is a 100% natural product obtained by evaporation of mineral springs in Karlovy Vary. Compared to ordinary kitchen or sea salt, it contains a variety of minerals and trace elements that naturally support the health of the mucous membranes of the respiratory tract. Rinsing the nose and gargling with a solution of Carlsbad salt helps remove impurities, allergens, viruses and bacteria, relieve swelling and inflammation, and regenerate irritated tissues.

Two wooden spoons with salt - one with sprinkled fine salt, the other with larger crystals, on a grey stone base.

How is Karlovy Vary salt different from regular salt?

Carlsbad salt is not just sodium chloride (NaCl), but a complex mixture of minerals that have a proven effect on health.

Ingredients of Karlovy Vary salt per 100 g:

  • Sodium (Na): 29 g
  • Sulphates (SO₄): 33 g
  • Chlorides (Cl): 11 g

  • Fluoride (F): 67 mg
  • Selenium (Se): 81 μg
  • Copper (Cu): 293 μg
  • Magnesium (Mg): 89.4 mg

These minerals have natural antibacterial, anti-inflammatory and regenerative effects. In addition, they promote fluid balance, hydration and mucosal resistance to infection.
