The Short Answer
Most store-bought stir-fry sauces are condiment catastrophes. They are typically thickened with modified corn starch, preserved with sodium benzoate, and sweetened with massive amounts of refined sugar (or high fructose corn syrup).
Primal Kitchen and Kevin's Natural Foods are the cleanest options on the market. They use coconut aminos instead of cheap soy sauce, are sweetened with real fruit or coconut sugar, and thicken their sauces with tapioca or arrowroot instead of modified corn additives.
Why This Matters
Stir-fry is supposed to be a healthy, vegetable-forward meal. But pouring a conventional bottle of sauce over your broccoli can turn a nutritious dinner into a sugar spike.
The sugar content is alarming.
Brands like La Choy can pack 20 grams of added sugar into a single serving. That is nearly as much sugar as a candy bar, poured directly onto your chicken and veggies.
The preservatives are unnecessary.
Many shelf-stable sauces use Sodium Benzoate to prevent spoilage. When combined with Vitamin C (often found in the veggies you're stir-frying), this preservative can potentially form benzene, a known carcinogen. While the levels are usually low, it's an unnecessary risk when cleaner brands use vinegar and salt for preservation.
What's Actually In Stir-Fry Sauce
Here is what you are typically buying when you grab a standard bottle like Kikkoman or La Choy:
- Modified Corn Starch — A highly processed thickening agent derived from corn (often GMO) treated with chemicals to withstand high heat and acidity. Is Ketchup Healthy
- Sodium Benzoate — A synthetic preservative used to extend shelf life indefinitely. Is Liquid Smoke Safe
- Caramel Color — An artificial brown dye used to make the sauce look "richer" than it actually is. Is Teriyaki Sauce Bad
- Soybean Oil — A cheap, inflammatory omega-6 seed oil used as a filler. Even sauces labeled "Sesame Teriyaki" often contain more soybean oil than sesame oil. Oils In Salad Dressing
- Flavor Enhancers — Ingredients like Disodium Inosinate and Disodium Guanylate are often used alongside MSG (or yeast extract) to trick your brain into thinking the food tastes better than it does.
What to Look For
Green Flags:
- Coconut Aminos Base — A cleaner, soy-free alternative to cheap soy sauce. Is Coconut Aminos Healthier
- Natural Sweeteners — Dates, pineapple juice, or coconut sugar.
- Tapioca or Arrowroot Starch — Clean, whole-food thickeners.
- Glass Bottles — Generally indicates a higher quality product that doesn't rely on plastic leaching.
Red Flags:
- "Sugar" in Top 3 Ingredients — It's a glaze, not a sauce.
- Sodium Benzoate — The hallmark of a dead, shelf-stable product.
- Modified Food Starch — A sign of cheap manufacturing.
- Caramel Color — Cosmetic chemistry for your food.
The Best Options
There is a massive quality gap between the clean brands and the conventional ones.

The Bottom Line
1. Switch to Coconut Aminos. The cleanest sauces (Primal Kitchen, Kevin's) use this as a base because it is naturally sweet and savory without needing additives.
2. Read the Sugar Label. If a sauce has more than 5-6g of added sugar, put it back. You are making dinner, not dessert.
3. Avoid "Modified" Ingredients. If the starch is modified, the sauce is highly processed. Look for tapioca or arrowroot instead.
