Chitosan is available generically from numerous manufacturers. Branded products include Diet Chitosan (Source Naturals) and Chitosan Support (Natural Treasures).
Chitin is found in fungi, arthropods and marine invertebrates. Commercially, chitin is derived from the exoskeletons of crustaceans (shrimp, crab and other shellfish).
If you have an allergy to shellfish, do not take Chitosan products.
Chitosan itself is the major source of the nutritional supplement glucosamine. When ingested, chitosan can be considered a dietary fiber. This product attracts dietary fats and helps to eliminate some of them from the body before they can be absorbed in the digestive system. Thus, Chitosan is considered a natural fat blocker.
There is some evidence that supplemental chitosan may have favorable effects on lipids and may be of some use in renal failure. There is some suggestion from available research data that it might be helpful in preventing atherosclerosis and could play a role in wound healing, some types of diabetes and liver disease or injury. Claims that it can help reduce weight, fight cancer, heal ulcers, aid digestion and boost immunity are unsubstantiated.
There are several chitosan supplements available. Those who use chitosan for cholesterol-lowering effects typically use 1000 to 1200 milligrams twice a day, taken before or after meals and with a glass of water. Chitosan can be contaminated with such metals as lead, mercury, iron, copper and arsenic.
Chitosan supplements should not be consumed within two hours of taking the fat-soluble vitamins A, D, E and K, carotenoids (e.g., lycopene, lutein), flavonoids (e.g., genistein, quercetin, ipriflavone) or prescription medication.
Suggested Use: Follow the directions provided by the manufacturer. Drink at least 8 glasses of fluid daily. For best results, take chitosan in conjunction with a multi-vitamin.
