Is Soy Sauce Gluten Free?

Traditional soy sauce is typically made with fermented soybeans and wheat. Because wheat contains gluten, most regular soy sauces are not gluten free. This is important for anyone with celiac disease or gluten sensitivity. 

However, the good news is that there are gluten-free soy sauces on the market, usually labeled as such, made with alternatives like rice instead of wheat.

If you’re trying to avoid gluten, look for terms like “gluten-free” or “tamari” on the bottle. Tamari is a type of soy sauce that’s often (but not always) made without wheat. Just be sure to check the label carefully because some tamari brands still contain gluten.

Choosing the Best Soy Sauce for Your Diet

Choosing a soy sauce that fits your gluten-free lifestyle means paying attention to ingredients and exploring good alternatives. Here are key tips to guide your choice:

Cooking Tips: Seasoning Smarter

If you’re looking to reduce ultra-processed foods or sodium, here are some ways to enjoy savory flavors without overdoing soy sauce:

  • Use fresh herbs and spices like garlic, ginger, and chili.

  • Try citrus juice or zest to brighten dishes.

  • Add small amounts of miso paste for umami (look for gluten-free varieties).
