Karen keeps track of the questions clients ask between their regular check-ins. This particular topic kept appearing for months, which told us that clients needed a clearer and more complete answer than we had been giving them individually. Karen and I judged these products based on more than a good first impression. We asked whether we would still be comfortable keeping and using each one in a real client's kitchen for an entire month, and products that became disappointing with repeated use were removed from the final list.
We coach clients through Optavia, now Trilivy, and its products are part of that program. We exclude them from lists like this one for two reasons. First, we earn from the program, and ranking its products would be a conflict of interest. Second, this guide is written for everyone, including the many readers who want good options without joining any program. The links below are affiliate links that pay us the same small commission on any product, so the ranking itself earns us nothing extra. Below are the top 5 best supplements for the low sodium diet, tested and compared, from $9.99 to $29.90.

What Should You Look for in Supplements for the Low Sodium Diet?
Supplements for a low sodium diet should state a low sodium figure and avoid added salt. The FDA defines low sodium as 140 mg or less per serving. Our full low sodium diet guide explains how to track sodium across a whole day.
Many supplements in Amazon search results for this keyword are salt tablets. Those tablets list up to 1,000 mg of sodium each. They treat low blood sodium, so they conflict with a low sodium diet.
Price on this list ranges from $9.99 to $29.90. Cost per serving ranges from under one cent for BulkSupplements to about $0.32 for Deal Supplement. Three of the five listings do not state a sodium figure in their bullets, so check the label.
Potassium deserves extra care. Potassium chloride and high potassium powders can be unsafe for people with kidney disease or certain medications. Ask your doctor or dietitian before you start any electrolyte supplement.
