Have you heard of Chitosan? A well-known fat blocker, it’s a marine fiber that attaches to the fat in the food you eat and prevents it from being stored as body fat.

While there are actually a lot of choices when it comes to a Chitosan product, only a very few contain pure, premium quality Chitosan.

FBlock Xtra by Absolute Nutrition is unmatched in purity and quality. FBlock contains 1 gram of pure Chitosan per serving, and undergoes an exclusive manufacturing process that enhances Chitosan’s effectiveness.

We don’t stop there – we’ve added Lipase, a digestive enzyme that acts as a fat emulsifier, increasing the fat absorption ability of FBlock. We’ve also included Calcium and Vitamin C, which aids in the absorption of Chitosan
