There is what many people call as "body balance chitosan" which monitors the levels and proportions of circulatory fats, blocking the fats in the digestive tract, thus reducing the bad cholesterol while providing the appropriate effect which may possibly aid the natural production of the body's good cholesterol. This property makes it possible for manufacturers of cholesterol and weight controlling products to use Chitosan as basic ingredient. Chitosan chemistry involves numerous biomedical applications whenever it is going to be discussed. Following are some of the most common biomedical applications involving the use of Chitosan. As far as chitin is considered, it is refined by taking out the cuticles from the shellfish, such as crabs, shrimps as well as lobsters. They are then converted into a powdery form which is deacetylated. It can also be exposed of definite chemical groups, permitting the compound to vigorously absorb fats. Because no extensive safety studies have been done to back up the claimed benefits of chitosan, every people must be careful and must seek for guidance from a health care professional before taking any chitosan product. Aside from those above mentioned chitosan warnings, there are other factors that must be considered before buying chitosan based products. Numerous studies and reports revealed that one of the major problem faced by people of entire world is obesity. However, still there is a hope for people suffering from obesity in the form of chitosan. Moreover, a wide range of natural alternatives for weight controlling and maintaining are under process of development. Individuals consuming chitosan in huge quantities are doing so with no scientific verification that it actually works with high-quality results. Critics are continuously trying to keep people away of using high amount of chitosan based medicines. They do not bother any of the claims brought to light by manufacturers of these medicines.
