Medical research shows that high fiber intake is important for good digestive health. Fibermax is a combination of Psyllium Husk and Oat Bran - two of nature's safest, lowest calorie sources of dietary fibers. The seed husks of psyllium yield a large amount of insoluble dietary fiber. This bulk producing fiber encourages normal elimination naturally without chemical stimulants and is non-addictive. Oat Bran is included in Fibermax because it has one of the highest levels of soluble fiber found in food and is a gentle bulk laxative for the occasional relief of constipation. For healthy digestion, try Fibermax.
