It smells really really bad. And it will stinks on every burps we have and the smell stays in our mouth for awhile. It's not good to smell like that. Feels like vomiting. This is my personal opinion and experience I had with this product. Some may not feel anything. But Kindly product manufacturer, try to give the product with less smell. I can't tolerate the smell. I don't know whether the product is working or not cause just now started using it. I hope many users will feel the same like I do with the smell.
