What Are Liquid Aminos?
Liquid aminos are a savory, salty seasoning with a distinct umami flavor, often used as a direct substitute for soy sauce. They come in two primary varieties: soy-based and coconut-based. Soy-based liquid aminos, like the popular Bragg brand, are made from treated soybeans and purified water, which breaks down the proteins into free amino acids through a process called acid hydrolysis. This unfermented process is much faster than traditional soy sauce production. Coconut aminos, on the other hand, are made from the fermented sap of the coconut palm and are completely soy-free. Both versions are naturally vegan and gluten-free, addressing common dietary restrictions.
The Case for Soy Sauce
Traditional soy sauce, most commonly the Japanese style (koikuchi shoyu), is a condiment with thousands of years of history, known for its rich, complex umami flavor. It is produced by fermenting a mixture of soybeans and roasted wheat with mold, salt, and water for several months. The fermentation process is what gives soy sauce its unique depth of flavor, which many chefs and home cooks prefer for certain dishes. However, this traditional preparation also means it contains wheat, making it unsuitable for those with celiac disease or gluten sensitivities. Furthermore, it is notoriously high in sodium, with a single tablespoon sometimes providing nearly half the daily recommended intake. While naturally fermented soy sauce offers some antioxidants and gut health benefits, chemically produced versions exist and may contain undesirable compounds. For those who love the traditional flavor but have dietary concerns, manufacturers also produce low-sodium and gluten-free versions.
A Nutritional Comparison: Liquid Aminos vs. Soy Sauce
To help determine which option is right for you, here is a detailed breakdown of their nutritional characteristics. The “healthier” choice truly depends on your specific dietary needs and what you prioritize in your diet.
| Feature | Liquid Aminos (Soy-based) | Coconut Aminos | Traditional Soy Sauce |
|---|---|---|---|
| Sodium Content (per tbsp) | 300-600 mg | 90-160 mg | 800-1000 mg |
| Gluten Status | Gluten-free | Gluten-free | Contains wheat/gluten |
| Presence of Soy | Contains soy | Soy-free | Contains soy |
| Fermentation Process | No (acid hydrolysis) | Yes, but from coconut sap | Yes (soybeans and wheat) |
| Flavor Profile | Mild, slightly sweeter | Sweeter, less salty | Salty, rich umami |
| Cost | More expensive | Most expensive | Often the least expensive |
Who Should Choose Liquid Aminos?
For certain individuals, liquid aminos provide a clear advantage due to specific dietary needs. They are an excellent option for those who are:
- On a Low-Sodium Diet: Coconut aminos, in particular, are the best choice for significantly reducing sodium intake compared to either traditional soy sauce or soy-based aminos.
- Gluten-Sensitive or Celiac: Both soy-based and coconut-based liquid aminos are naturally gluten-free, making them safe for those with gluten-related disorders.
- Avoiding Soy: Coconut aminos are the ideal substitute for those with a soy allergy or sensitivity, as they are entirely soy-free.
- Seeking Cleaner Ingredients: Liquid aminos often contain only a few ingredients—soybeans or coconut sap and water—and are free of chemical preservatives like sodium benzoate.
Who Should Choose Soy Sauce?
Despite the health advantages of aminos, soy sauce remains a staple for many, and for good reason. It may be the better choice for people who:
- Prioritize Traditional Flavor: The deep, complex umami profile of traditionally fermented soy sauce is hard to replicate. For authentic flavor in many dishes, it is the superior choice.
- Have No Dietary Restrictions: If you don't need to limit your gluten or sodium intake, the classic taste of soy sauce might be all you need, provided you choose a naturally brewed variety to avoid chemical processing.
- Are on a Budget: Soy sauce is often more widely available and significantly less expensive than its liquid aminos counterparts.
Conclusion: Making the Best Choice for You
Determining if liquid aminos are healthier than soy sauce is not a one-size-fits-all answer. For individuals managing sodium intake, avoiding gluten, or steering clear of soy, liquid aminos—especially the coconut variety—are a clear winner. They offer a milder, slightly sweeter flavor and a cleaner ingredient list. However, for those who value the rich, traditional umami flavor and have no dietary restrictions, naturally fermented soy sauce remains an excellent culinary choice. The final decision should be guided by your health priorities, flavor preferences, and budget. Regardless of your choice, remember that both condiments are best enjoyed in moderation.

The Difference in Production
Fermentation vs. Acid Hydrolysis
Liquid aminos and soy sauce utilize fundamentally different methods of production that impact their final nutritional profile and flavor. The most significant contrast is fermentation. Traditional soy sauce is aged for months, which develops its deep, complex flavor. Liquid aminos, by contrast, are typically created through a process called acid hydrolysis, which rapidly breaks down proteins into amino acids without fermentation. This difference explains why liquid aminos often have a milder, less nuanced taste.
Flavor Adjustments for Substitutions
When swapping liquid aminos for soy sauce, consider adjusting your recipes to compensate for the flavor differences. Because liquid aminos are typically less salty, you might need to add a pinch of salt to your dish to achieve a similar taste profile. Coconut aminos, being noticeably sweeter, may require an extra bit of seasoning to balance out the sweetness, especially if used in large quantities. Experimenting with a combination of the two might also help you find the perfect balance for your palate.
Health Impacts Beyond Sodium and Gluten
While sodium and gluten are primary concerns, it's worth noting other health aspects. Traditional soy sauce contains histamines and tyramines, which can affect individuals with sensitivities. Chemically processed soy sauces can contain the potentially toxic compound 3-MCPD, another reason to favor naturally brewed varieties. Liquid aminos generally avoid these issues. On the other hand, the claims about the amino acids in liquid aminos providing a significant health boost should be taken with a grain of salt, as the serving size is too small to make a major nutritional impact.
Recipe Ideas with Liquid Aminos
To easily incorporate liquid aminos into your cooking, try these simple applications:
- Salad Dressings: Add a splash of liquid aminos to your homemade vinaigrette for a savory kick.
- Stir-Fries: Use as a marinade for tofu, vegetables, or meat before cooking.
- Marinades and Sauces: Replace soy sauce in any sauce or marinade recipe for a lower-sodium, gluten-free option.
- Dipping Sauce: Mix with a little ginger and sesame oil for a simple, healthy dipping sauce.
The Final Word
Both liquid aminos and soy sauce can have a place in a healthy diet. The key is understanding their differences and choosing the one that best aligns with your health goals and taste preferences. If you're prioritizing lower sodium and need a gluten-free or soy-free solution, liquid aminos are the healthier choice. For the unmatched flavor of fermentation, stick with naturally brewed soy sauce. Ultimately, moderation is key for any high-sodium condiment.
