After that, it was in 1878 while Ledderhose recognized chitin to be composed of glucosamine as well as acetic acid; it was not in fact until 1894 that Hoppe-Seyler identified the oriented chitin, chitosan. In the beginning of twentieth century, a number of inquiries and searches considered chitosan as their theme of schoolwork. Looking at these pieces of evidence, one might be suitably convinced that chitosan's claims are in fact true. However, when taking the designs of the studies on chitosan into consideration, the evidence appears in a much different light. In the first place, the 1994 ARS Medicina Report and others that support it appear to be loosely designed. Chitosan used in medicines not only hold and remove harmful fat elements from human body but may also eliminate many other healthy ingredients. Moreover, Experts and critics also stressed over the less or no use of these medicines as there is an immense possibility of adverse dangers of chitosan because of containing impure chitin. There is a possibility in theory that it could block the absorption of the fat-soluble vitamins, such as Vitamins A, D, E and K. Also, chitosan may block the absorption of the essential fatty acids, like omega 3 and 6. Therefore, it necessary to be sure that you take a vitamin supplements at least an hour or so before taking the chitosan. According to some, Reduce Chitosan binds to the intestinal lining where it tightly binds dietary fats and lipids prior to the absorption in the body. As a result, the dietary fat is prevented from entering into the bloodstream because when the dietary fat is bound to the chitosan fiber, it becomes a large mass which cannot be absorbed in the body. 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 helps, certainly, while the product is taken in accordance with what is intended for.
