If a person with high blood pressure wants to use low-sodium salt instead of regular salt, what should they confirm with their doctor first?

First, give the ingredient list and nutrition facts panel of the product you plan to buy to your doctor or dietitian, and tell them about your current medications, other medical conditions, and usual diet. You can ask directly: "Is this product suitable for me, and what restrictions should I follow when using it?" Do not judge suitability based only on the words "low sodium," and do not use changing salt as a reason to alter your existing treatment plan.
