Clinical Assessment

Tamari, a Japanese soy sauce variant, is generally made without wheat, making it a popular choice for those seeking gluten-free options. However, production methods can vary, and cross-contamination during manufacturing is a potential risk. Understanding the full ingredient list and manufacturing process is crucial for those with celiac disease or gluten sensitivity.
