I bought this product because I've been having stomach and digestive problems. I was diagnosed as a celiac with severe malabsorption, meaning that my insides were severely damaged by the gluten over the past decades. There's really very few things that doctors believe can help heal your intestines, or help give them time to heal. L-Glutamine is one, and Slippery Elm is another. Slippery Elm coats the esophagus and digestive tract, allowing it to heal. You can buy it in capsules, which is possibly more convenient for some people. Personally, I'd rather save some money, so the Now Foods brand in the powder form is perfect! I use about 1/2 teaspoon twice a day, and mix it with my coffee, so I don't even taste it. It just thickens it up a bit. I've been using it for about two weeks, and think that food doesn't upet my system as much as it used to. I've read that it helps other people with various stomach problems. Gluten-free.
