It is one of the most popular dietary supplements as the source of natural fiber according to several reviewers. This dietary supplement is quite effective and is much easy to be swallowed. This Natrol Chitosan contains about 95% of deacetylated Chitosan to enhance its solubility capacity. Moreover, it is all-natural product with no wheat, milk, yeasts and glutens etc. 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. He actually was performing search about mushrooms and he isolated something named as chitin after sometime. After about twenty years, another researcher revealed that it is also present in insects and some plants as well. The name chitin is derived from Greek word, i.e. tunic or envelope. The idea was further elaborated in 1843 by Lassaigne. Chitosan is nothing but just the most refined form of natural chitin, which is obtained from shells of crustaceans and shellfish. There are numerous biomedical applications associated with Chitosan. Now-a-days, liquid Chitosan is frequently used by people of different ages in order to lose their excess weight. It is significant to be noticed that soluble vitamins must be taken before/after having LipoSan Ultra during meal times. It has been suggested that LipoSan Ultra Chitosan interferes the intake of vitamins. However, there is no biomedical research which can support this assumption. Moreover, always take plenty of water while using LipoSan Ultra Chitosan to avoid chances of any kind of blockage. 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.
