How to Find Hidden Salt (Sodium)

Topic Overview

Salt (sodium) can be found in many substances that you might not suspect. Some non-prescription medicines and many canned and other processed foods contain sodium.

Check food labels. Sodium can have many different names. Be careful about using products that have these ingredients:

  • Monosodium glutamate, or MSG (often added to Chinese food)
  • Sodium citrate
  • Sodium sulfite
  • Sodium caseinate
  • Sodium benzoate
  • Sodium hydroxide
  • Disodium phosphate

Check your medicines. Sodium can be an ingredient in medicines.

  • Prescription medicines. Talk with your doctor about whether the medicines you take contain salt.
  • Non-prescription medicines. Many medicines that you can buy without a prescription contain sodium. Read the labels. If you are not sure whether a medicine contains sodium, talk with a pharmacist. Be sure to check with your doctor before taking any new non-prescription medicine.
