A high-sodium diet is linked to various health concerns, including high blood pressure and heart disease. For those looking to reduce their salt intake, soy sauce—a staple in many kitchens—is a key place to start. While most standard soy sauces pack a high sodium punch, there are a growing number of specially formulated low-sodium options and other alternatives available.
The Lowest Sodium Option: Mrs. Taste Less Sodium Shoyu
For those seeking the absolute lowest sodium content, Mrs. Taste Less Sodium Shoyu stands out. With a remarkably low 180mg of sodium per tablespoon, it is one of the most sodium-conscious options on the market. This product is also zero-calorie and sugar-free, achieving its authentic, salty flavor using Himalayan pink salt. It is an excellent choice for individuals on very strict low-sodium diets who still desire the distinct shoyu taste without compromise.
Leading Reduced-Sodium Soy Sauce Brands
Beyond the lowest-sodium specialty brands, many mainstream manufacturers offer reduced-sodium versions of their classic products. These are more widely available and offer a significant reduction compared to their standard varieties.
- Kikkoman Less Sodium Soy Sauce: One of the most popular brands, Kikkoman's less sodium version contains 590mg of sodium per tablespoon, which is approximately 40% less than their regular soy sauce. The sodium is removed through a special process after the fermentation is complete, ensuring the flavor is preserved.
- San-J Reduced Sodium Gluten-Free Tamari: As a naturally brewed tamari, this option provides a rich, complex flavor. It is also gluten-free, which is an important consideration for many users. The sodium content typically hovers around 700mg per tablespoon.
- Yamasa Less Salt Brewed Soy Sauce: Yamasa offers a less-salt option with a notable reduction from their standard sauce. This is a traditional Japanese-style sauce popular among those who prefer that flavor profile.
- Pearl River Bridge Lite Soy Sauce: This Chinese brand offers a "lite" version with 35% less sodium than its regular soy sauce. It's a great choice for Chinese cuisine where controlling sodium levels is desired.
Lower-Sodium Soy Sauce Alternatives
For those needing a drastic reduction in sodium or avoiding soy altogether, several alternatives provide a savory, umami flavor.
- Coconut Aminos: Made from the fermented sap of coconut blossoms, coconut aminos are a popular soy-free and gluten-free alternative. With only around 270mg of sodium per tablespoon, they offer a slightly sweeter, milder flavor than soy sauce.
- Homemade Substitutes: You can create your own low-sodium alternative at home using ingredients like broth, balsamic vinegar, molasses, and spices. This allows for complete control over the sodium content, although the flavor profile will differ.
The Surprising Sodium Levels of Light vs. Dark Soy Sauce
A common misconception is that "light" soy sauce is lower in sodium than "dark" soy sauce. In fact, the opposite is often true. Dark soy sauce is aged longer and has added caramel or molasses, giving it a richer, sweeter flavor and darker color. This depth of flavor often makes it taste less salty, and it can have a lower sodium content than its lighter counterpart. Always check the nutrition labels, as brand variations exist.

Practical Tips for Reducing Soy Sauce Sodium
- Measure your servings: Instead of free-pouring, measure out your soy sauce to control the amount you use.
- Dilute with other liquids: Mix soy sauce with water, rice vinegar, or citrus juice to maintain volume while lowering sodium.
- Enhance with umami: Boost flavors with other umami-rich ingredients like mushrooms, nutritional yeast, or seaweed to use less soy sauce.
- Season strategically: Use less soy sauce during the cooking process and add a splash at the end, as the flavor will be more concentrated.
- Check the label: Always read the nutritional information, as sodium levels can vary significantly even among products with similar descriptions.
Conclusion
For individuals seeking the absolute lowest sodium soy sauce, Mrs. Taste Less Sodium Shoyu is the top contender, offering an impressively low 180mg per tablespoon. However, several other excellent and more readily available options exist, including Kikkoman Less Sodium and San-J Reduced Sodium Tamari. Alternatives like coconut aminos provide another path for significantly lower sodium intake. The key takeaway is to read labels carefully, as terms like "light" can be misleading when it comes to sodium content.
