  • Publication number: 20200187536
    Abstract: The present invention provides table salts. The said table salts contains 50 to 600 mg/kg of strontium. The strontium-rich table salts provided by the present invention has significantly higher strontium content than traditional common table salts. As one of the essential trace elements, strontium plays an important role in human health. The said table salts provided by the present invention are rich in strontium, which can be assimilated by human body during taking the said table salts. Moreover, the strontium content in the table salts provided by the present invention ranges from 50 to 600 mg/kg, which enables human body to get enough strontium to meet human needs when taking normal amount of the said table salts daily.
