It is most unfortunate that only one well-designed study on chitosan, involving humans as subject, has been published. That study was conducted in 1999 by the European Journal of Clinical Nutrition, showing that chitosan supplements were no better than a placebo in reducing body weight. 34 overweight subjects were actually involved in the study. The chitosan ingredient used in PBL's Reduce Chitosan is said to be unsurpassed in its quality and purity. It goes through a process called deacetylation, which refers to the removal of the acetyl groups. What's more, Lipase, a digestive enzyme is added to Reduce Chitosan in order to help in emulsifying the fats that you ingest, making it a superior fat absorber. This Ephedra-free product normally takes only five minutes and even less time to eliminate fat present in your stomach. This means you can take LipoSan Ultra Chitosan exact at your mealtime. This contrasts to numerous other weight controlling products, which are normally prescribed to be taken an hour before your meal. As name implies, this type of Chitosan has liquid appearance Liquid Chitosan is mostly available in yellow color plus no smell and taste This Chitosan variety contains about 0.5 percent of protein content Deacetylation degree appears to be more than 90%, which may exceed to 95% percent if colloidal method is used for measurement Viscosity of liquid Chitosan comes out to be 50cps if Brookfield viscometer is used as measuring equipment pH level of liquid Chitosan is less than 5.5 Liquid Chitosan shows 0.5% of insolubility if 20 grams of this substance is dissolved in distilled water of 100ml. 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. 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. Basically, Chitosan is naturally available form of fiber generally found in crustaceans and shellfish species.
