Good Fiber Source
Works well without being too harsh. Helps with medications that may cause you to be blocked.

Convenient for travel
Good for travel when you may not have a glass, a spoon and a place to mix the powdered version with water. Make no mistake, you must still drink at least 8- 12 ounces of water with the capsules, and one serving is 5 capsules. But, this is a bulking agent,!so that is to be expected.
