Chitosan is an indigestable, fibre-like substance, extracted from marine shells, such as crabs and shrimps. It binds to fat molecules during digestion and aids their removal from the gut without being absorbed. Chromium and the powerful Indian herb Gymnaema are added to the formulation for maximum efficacy. HealthAid Chitosan capsules can be taken as part of a calorie controlled diet to help with excess body fat. While taking Chitosan products, certain vitamins and minerals may be bound to the fat and lost from the body. Therefore, it is advisable to take a well-balanced HealthAid multivitamin and mineral supplement to safeguard dietary intake of these important nutrients.
