In theory, Chitosan is an ideal solution to those who find themselves “cheating” in their diets. Chitosan is a fiber-like fat blocker that is derived from shells of marine animals such as crab and shrimp and forms a gelatin-like substance when consumed. This substance is thought to bind to fat before it can be absorbed and then travel through the digestive system, ultimately being eliminated from the body.
Suggested usage for this supplement may vary, but should always be taken about 15 minutes prior to a meal.
Side effects may include deficiencies in fat-soluble vitamins (A, D, E, K), diarrhea and gastrointestinal problems. Given the lack of conclusive studies on this supplement, it is highly recommended to consult a physician before taking it
