I wrote the makers of DA and told them that mannitol (a sugar alcohol) was not a good ingredient to be putting in an IBS product since so many IBSers were sensitive to it. Here's the response:
They have considered taking the sweeteners out, and hopefully will be
so very soon. You may purchase our non chewable tablet that is sold online
at rofay.com or drugstore.com, and sold in Costco. This box contains 92
caplets of our non chewable IBS formula. Thank you for your interest in our
product, and have a nice day.
So, if you want DA but can't have the mannitol, you can get a pill to swallow without the sugar alcohol.
