Updated with notation on whether each ingredient is gluten or dairy.
There are so many everyday household products that contain gluten. So many. Things like price stickers, stamps, envelopes, medicine, vitamins, protein shakes, energy bars, even toothpaste. Although most stamps and envelopes are now gluten free, there are still some older brands that contain gluten (a call to the company can verify this). Soaps, shampoos, cosmetics, lip balms, children’s stickers, mouthwash, detergents, lotions, moisturizers, and sunscreens can also contain gluten. Manufacturers don’t always clearly label their products “gluten free” or “dairy free”, which is why we quickly need to become a label-reading aficionado! We love Acure shampoo, face wash, moisturizer, and scrubs. Himalaya or Epic Dental Toothpaste. Health Food stores carry allergen-free brands, but I find products to sometimes be cheaper on Amazon.com
