Does melatonin have gluten in it?

Melatonin itself is a hormone naturally produced by the body and does not contain gluten. However, melatonin supplements can vary in their formulation, and some may include additional ingredients or fillers that could contain gluten. It's important to check the label or consult the manufacturer to ensure that a specific melatonin product is gluten-free. If you have gluten sensitivities or celiac disease, look for supplements specifically labeled as gluten-free.
