Hello Cursing Crohn's
Welcome. You do have a problem here and this is the best I can offer you.
Salt substitutes are edible products designed to taste similar to table salt, which is mostly sodium chloride. They usually contain mostly potassium chloride, which when consumed increases potassium intake. Because excess potassium intake can cause potentially fatal hyperkalemia, it is advisable to check with one's physician and pharmacist before using salt substitutes based primarily on potassium chloride.
I do not know the name of any salt substitute without potassium.
Good Luck and hopefully someone wiser then me will post to you.
