Excellent!
I've been using this product for more than a year and have found it to be very helpful in controlling my gastro problems.  I am lactose intolerant and also have irritable bowel.  After using it for several months (I've been taking one pill a day, rather than two), my IBS is more in control and the lactose intolerance is less sensitive.  I would recommend giving it a try.  I've found that it's convenient to buy from Amazon and the price is competitive.
