SafeSalt is exactly as the name suggests: salt that is safe for your horse and their stomach. A unique electrolyte (NaCl; sodium and chloride) to overcome problems with palatability, gastric upset and gastric ulceration. Individual grains of salt coated in special oil which will not dissolve in the mouth or stomach. The oil coating dissolves in the small intestine where electrolyte uptake is optimal and gentle on the stomach unlike ordinary electrolytes. Approx. 8 month supply, or ideal for multiple horses.
