The active ingredient is Chitosan a marine dietary fiber derived from shellfish that is Lipophilic (positively charged and attracted to negatively charged fats and cholesterol). Dietary fiber is an indispensable adjunct to a balanced weight/fat loss program. Chitosan fiber binds to fat and cholesterol in the intestinal tract and encapsulates them preventing them from entering the bloodstream. The large mass of indigestible Chitosan and fat is then cleared from the body naturally. F Block has added cofactors Vitamin C which studies have shown work to enhance the effectiveness of Chitosan by swelling the fibers as well as Lipase a natural Proteolytic enzyme that helps break down fat and vegetable cellulose that help physically dislodge hard to get at fat lipids and bile acids.
