Gluten is a protein found in wheat, barley and rye, but can be hidden in many products. Many people are gluten intolerant, and a lot of people do not realize that wheat is often used as a filler in supplements. Typically, the inactive ingredients may contain gluten.
If you’re gluten intolerant or sensitive, it’s important to look for supplements that are gluten-free. Eyecheck products contain no gluten.
