This is the best fiber capsule supplement hands down. Most drugstore brands include things like shellack and other questionable ingredients. Konsyl doesn't have all the additives, which I think is best. If you want to get your fiber in a convenient capsule form then this product will get the job done very nicely. I looked around at several drugstores, but they only carried the powdered mix, which I didn't want. I only purchased one bottle this time from Amazon, but shipping was free due to other items I included in the order.
