They do not bother any of the claims brought to light by manufacturers of these medicines. Reason behind this approach of critics is the non-availability of medical evidences supporting that there are no dangers of chitosan. This is why, most of critics and biomedical experts strongly oppose the use of medicines composed of chitosan. Originally, it was utilized in detoxification of water but now its usage has been expanded to a great extent. Today, Chitosan is manufactured artificially in laboratories in two forms. One is flakey type of dry form whereas the second one is liquid Chitosan. Chitosan is known all over the world as a simple substance extracted from chitin present in outer shells of crustaceans. Working mechanism of this supplement is same as that of many other Chitosan containing products but differs in resulting effects. Obese people can get the most favorable and high rated results by making use of chitosan contrasting to its counterparts. Moreover, when overweight individuals take this supplement along with diet having lower calorie then it will surely lower the fat you intakes. One of the most commonly cited studies on chitosan by the marketers and manufacturers of chitosan-based products is the 1994 ARS Medicina (Helsinki) Report. In this study, it was found out that test subjects lost eight percent of body fat and reduced cholesterol by thirty-two percent in four weeks. Secondly, there are various studies on chitosan which revealed that the substance lowers plasma cholesterol and triglycerides and improved the HDL cholesterol level. As said by a number of studies, the frequent effect of this combination proposes that the fusing of polyvinyl and alcohol chitosan ameliorates the tensile power as well as elasticity of films equally in dry as well as wet states. In addition, the joining with the glutaraldehyde improves tensile potency as well as decreases the extension of mixes. They claim that Chitosan is fully capable of binding fats to molecules in the user's digestive tract. As a result it prevents the user's body from fat absorption and ultimately improves the weight loss. Online available Chitosan message boards not only offer discussion opportunities but these also provide all significant information about Chitosan.
