Many salt substitutes replace sodium with potassium. Whether that is appropriate depends entirely on your situation, your labs, and your medicines — so this guide is a list of questions rather than an answer.

Bring these questions to your care team

  1. Is a potassium-based salt substitute appropriate for me at all right now?
  2. Do any of my current medicines change how my body handles potassium?
  3. If it is not appropriate, what would you suggest instead for flavor?
  4. Should anyone else in my household avoid keeping it on the table?
  5. If my situation changes, when should I ask about this again?

Reading the package while you wait for an answer

Substitute products vary. Some are entirely potassium based, some are blends, and some are herb mixes with no added mineral at all. The ingredient list will tell you which kind you are holding.

What not to change on your own

  • Do not start using a potassium-based substitute because a general article, a shop assistant, or a family member recommended it.
  • Do not assume a product marketed as natural or heart-healthy is neutral for you.

Bring anything on this list to your care team instead of acting on it yourself.
