Absolute Nutrition has created F-Block Xtra which may assist in impeding fat absorption by 'gelling' with fat in the small intestine.Taken before a meal, it may bind to the fats and assist in their elimination.

Each F-Block capsule contains a whopping 500 mg chitosan. Sure there are plenty of chitosan products out there, but ours goes through a process called deacetylation, making it superior in its purity. It also increases the solubility of the chitosan fiber.

F-Block also contains added Vitamin C to boost its potency and the digestive enzyme lipase to help break down the fats for better absorption. Vegetable cellulose is used to dislodge hard to get at fat cells. That's why we added the word "Xtra".
