Chitosan is a soluble fiber composed of chitin, which is a component of the shell of shellfish. Fibers such as chitosan can absorb many times their weight of fat and cholesterol. Since cholesterol is normally secreted with the bile and reabsorbed in the intestine, fibers like chitosan can help maintain healthy cholesterol levels in those already within normal range. Absorbed fat and cholesterol are excreted through the bowel, which may improve bowel function. Moreover, chitosan may facilitate the depletion of excess body fat in humans under free-living conditions. Ascorbic acid (vitamin C) helps activate chitosan in the stomach and intestine. It is important to take pure ascorbic acid to enhance the effects of chitosan. Buffered or mineral ascorbates will not work as well.

Chitosan supplements should not be consumed within two hours of taking fat-soluble or oil-based supplements such as CoQ10, vitamins A, D, E and K, or prescription medication. To avoid the possibility of esophageal obstruction, always drink at least 10 ounces of water with fiber supplements, followed by another glass of water. Do not use if abdominal pain, nausea or vomiting is present, unless directed by your physician. Those allergic to shellfish should not use this product.

To avoid the possibility of esophageal obstruction, always take with at least eight ounces of water. Consume immediately, followed by another glass of water. Fiber may decrease the absorption of minerals such as zinc, copper, iron, calcium, and magnesium if used concomitantly.
