Question: is bayer aspirin gluten free?
Answer: We don't add gluten to our products. However, we can't guarantee they are 100% gluten free since our products are produced in a facility that manufactures and packages items that may contain gluten. DOES BAYER® ASPIRIN CONTAIN CAFFEINE, AND IF SO HOW MUCH? Bayer® Back & Body contains 32.5mg caffeine in each pill.
