Salt is one of the most common seasonings in the world. It makes food taste better, preserves meals, and brings out natural flavors. However, too much salt—especially table salt—comes with a cost. According to the Centers for Disease Control and Prevention (CDC), most Americans consume over 3,400 mg of sodium daily, well above the recommended 2,300 mg limit [1]. Over time, this excess can raise blood pressure and increase the risk of heart disease and stroke.
That’s where low sodium salt alternatives come in. They allow you to keep the flavor you love while cutting down on the sodium that strains your heart and blood vessels. In this article, we’ll look at the best low sodium salt options, how they work, and which brands are worth keeping in your kitchen.
What Is Low Sodium Salt?
Low sodium salt looks and tastes similar to regular salt but contains less sodium chloride. Instead, it often includes potassium chloride, magnesium sulfate, or other mineral blends. These substitutions lower the sodium content while still giving your food a salty taste.
The benefit is clear: less sodium intake helps maintain healthier blood pressure. However, it’s important to note that not all low sodium salts are created equal, and some may not be suitable for individuals with kidney disease or certain medical conditions. Always check with your healthcare provider if you’re unsure.
Top Benefits of Low Sodium Salt
Supports Blood Pressure Control
Cutting sodium can directly benefit heart health. A 2021 NEJM study found that using a reduced-sodium salt substitute lowered the risk of stroke and major cardiovascular events [2].
Helps Reduce Risk of Heart Disease
Since high sodium intake is linked to hypertension and heart strain, switching to a low sodium alternative can be a small but impactful dietary change.
Allows You to Keep the Flavor
Nobody wants bland meals. These alternatives maintain flavor without overloading your body with sodium.
May Provide Extra Minerals
Some blends add potassium or magnesium, both essential minerals that support overall health.
The Best Low Sodium Salt Alternatives
When choosing a lower salt alternative, look for quality taste, and brand transparency. Below are some of the best options available:
