Is Three Musketeers gluten-free?

The short answer to this question is no, Three Musketeers is not gluten-free. This popular candy bar is produced by Mars Inc., and although its nougat and chocolate ingredients do not inherently contain gluten, the company states that Three Musketeers may contain trace amounts of gluten due to cross-contamination during production. Therefore, it’s not safe for people with celiac disease or gluten sensitivity.
