What is gluten?
Gluten is a protein found in most wheat products, and acts as the “glue” that helps to hold wheat, barley, kamut, spelt, farro, durum, bulgur, rye, and semolina together to maintain their shape.
You can find gluten in whole grains, but also in many processed foods as well. If you purchase wheat bread, there will be gluten in it, because wheat by nature has gluten.
Many processed foods have hidden gluten in them in the form or gluten or wheat derivatives. These are also in the form of flavorings, binders to keep ingredients together, or other additives.

How to find gluten-free oyster sauce
The best way to find a gluten-free oyster sauce brand is to review ingredients lists and look for gluten-free labels.
Look for the terms “soy sauce” or “wheat flour” on ingredients lists as these are hidden names of gluten. You might also see “caramel color” or “yeast extract” which can sometimes indicate gluten (but not always).
The best way to ensure you’re using an oyster sauce that is safe for your gluten-free diet is to look for a gluten-free label, even if you can sometimes handle trace amounts of gluten.
As per the FDA, any product with a gluten-free label or “certified gluten-free” label can have no more than 20ppm of gluten in the product.
You can trust the brands with these labels. I would likely not trust those without one, but if you wish to, review ingredients lists before buying.
