Mars does not make a gluten-free Twix, so the brand should be avoided. For a similar caramel-cookie-chocolate experience, look to dedicated gluten-free candy bars.
Gluten-free alternatives include bars from brands like Schär, or GF "twin bar" style treats; many GF chocolate bars (e.g., Hu, Enjoy Life) offer a safe chocolate fix.

Celiac Safety Glossary
- Celiac disease
- Celiac disease is a serious autoimmune disorder in which ingesting gluten — a protein found in wheat, barley, and rye — triggers an immune response that damages the small intestine's villi, affecting approximately 1 in 100 people worldwide according to the Celiac Disease Foundation.
- Gluten
- Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
