Psyllium is a natural dietary fiber made from ground husks of psyllium seed, which has the ability to hold water and form bulk. Psyllium holds water better than bran, so smaller amounts are needed to be effective. Metamucil, Effer-Syllium, Perdieum Fiber and Fiberall powder or wafers are brands of psyllium. Synthetic or man-made bulk forming products such as Citrucel or Fiberall Chewable Tablets are similar to psyllium. They work the same way and may cause less gas.
Many pharmacies sell generic brands of bulk agents which are less costly.
Begin by taking 1 or 2 rounded teaspoonfuls of powder 2 or 3 times a day with meals. These agents are very safe and if you are not getting desired results, you should increase the daily dose. If preferred, fiber wafers may be used. The wafers should also be eaten with 8 ounces of your favorite beverage and, for best results, followed by another glass of liquid. Start with 2 wafers a day and increase to 2 wafers 3 times a day.
