Though most of us do our best to eat the healthiest diet possible, oftentimes—such as when we’re visiting friends or dining out at restaurants—we find ourselves in a situation where there’s just too much fat in the meal. That’s where the triple-nutrient ChitoLean (pronounced: CHIT-uh-lean) formula is ready to go to work.

Chitosan (pronounced: CHIT-uh-san) is an indigestible fiber, meaning it traverses the GI tract without being absorbed. En route, chitosan—with a powerful assist from vitamin C—effectively binds fat and blocks its absorption. N-acetyl-l-carnitine (aka “acetyl l-carnitine”) accompanies the formula to ensure effective fat oxidation (“burning”).

ChitoLean FAQs

Are your supplements 3rd party tested?

Yes, every Hammer Nutrition supplement is 3rd party tested in compliance with the FDA’s regulations, 21 CFR Part 111 – Dietary Supplements. All the raw materials for each supplement we produce are tested for purity, strength, identity, and integrity. In addition to raw material testing, every Hammer Nutrition supplement is also tested in every stage of production—blending, encapsulation / powder-filling, packaging components and finished goods—before being released for distribution.

How to Use

Take 2–3 capsules just before or during a high-fat meal.


Be sure to drink at least 8 oz of water when using ChitoLean.

Wait at least 4 hours before consuming healthy fats or fat-soluble vitamins and medications.


5 Secrets of Success

How To Hammer


Chitosan (pronounced CHIT-uh-san) is a fiber composed of chitin, which is a component of the shell of shellfish. The strong positive charge carried by the chitosan molecule causes it to bind negatively charged substrates such as fat. Chitosan effectively binds fat in the intestine, blocking absorption, and it has also been shown to lower blood cholesterol in animals and humans. As a result, dietary supplementation with chitosan may not only assist with weight loss and normalization of cholesterol levels, it may also help inhibit the formation of atherosclerotic plaque (deposit of fat and other substances that accumulate in the lining of the artery wall).

Strictly regarding weight loss, one study involved 150 overweight men and women. One group was given 3 grams of chitosan daily, while the other was given a placebo. Both groups were provided with the same self-monitored behavior-modification program. After 60 days, the chitosan group lost an average of 2.8 pounds, while the placebo group lost 0.6 pounds. The chitosan group also had greater reductions in fat percentage and fat mass than the placebo group, along with an improvement in body composition.

N-Acetyl-L-Carnitine is an amino acid and, like all forms of l-carnitine, it is THE nutrient that transports fatty acids into cells for the production of energy. Without adequate supplies of l-carnitine, fatty acids cannot be effectively burned as a fuel source. Exercise depletes carnitine levels, as does the aging process.

Vitamin C helps activate chitosan in the stomach and intestine into a fat-absorbing gel, increasing the fat-binding effects of chitosan. Research on pigs using either chitosan, or a chitosan/vitamin C combination concludes, “Vitamin C increased the fecal fat excretion by chitosan in guinea-pigs, thereby reducing body weight gain.”
