One of the most popular products available is the Reduce Chitosan, formulated and developed by Performance Biomedical Laboratories (PBL). What is Reduce Chitosan? As the name implies, PBL's Reduce Chitosan contains the ingredient chitosan, which works to bind to some dietary fat and removes it from the body rather than allowing it to be absorbed. Many other crustaceans may also be used in order to get Chitosan, which is in actual a compound of chitin. Chitin is the fundamental polymer found in the hard outer shells of most of the aquatic arthropods. Chitosan is the designer fiber present in chitosan plus to attract and take hold of fat present in digestive tracts of human beings. If we would observe it considering it as a substance, chitosan then seems chemically resembling the plant fiber. The particular fiber is known as cellulose. The thought of using chitin as a product for reducing weight was emerged from the concept that chitosan weight loss products are capable of considerably connecting with fat molecules as well as adapt them into a type which the human body does not take up. This medicinal product has been advertised heavily as a fat magnet at different forums like television, newspapers and internet etc. It is claimed by makers of Natrol Chitosan that it is one the most excellent supplement for extra weight loss. This product is actually developed by Natrol, Inc. and so is the name given to it. Further studies on chitosan were conducted, but all of them, however, have shown that chitosan didn't block fat. As you may notice, these studies on chitosan have the same findings as the European Journal research. And, even worse, chitosan has been shown to block some vitamins and minerals. Taken into consideration, what the advertisements are saying seem to be media hype, thus the search for a miracle dietary supplement continues. However, if we will look at those animal studies and the first published 1999 clinical trial done on humans, results suggest that chitosan could inhibit the absorption of minerals and fat soluble vitamins. Also, studies have revealed certain adverse side effects of chitosan to pregnant women, particularly on the growth of children and the outcome of pregnancy.
