Acid reducer.
I use Prelief because I have a bladder problem (interstial cystitis) and it takes the acid out of foods which contain acid (i.e. tomatoes, lots of fruit, even lots of veggies, also coffee and lots of fruit juices), so without this product, I would not be able to eat much! It is expensive I admit. I wish a U.K. company would look into manufacturing it.
