Chitosan is a marine fiber that really does the job of absorbing fat. There are plenty of chitosan products out there, but only a handful contain the purest of pure chitosan. FBlock by Absolute Nutrition is a superior fat absorber.

Our chitosan ingredient is unsurpassed in it's quality and purity. FBlock's chitosan goes through a process called deacetylation, which referes to the removal of acetyl groups. This is a process that increases the solubility of the chitosan fiber.

But there's more. The digestive enzyme lipase is added to our formula to help in emulsifying the fats that you ingest, making it a superior fat absorber. That's why we call it Fblock xtra. FBlock is also fortified with calcium and vitamin C. The vitamin C aids in boosting the effectiveness of chitosan, vegetable cellulose is added to the formula to dislodge hard to get at fats.
