What is LipoSan Ultra?

Zy4f6hcaLipoSan Ultra® is a natural dietary supplement for effective weight management. In the digestive system, LipoSan Ultra® complexes and binds with dietary fat in such a way that it is not absorbed by the body.

LipoSan Ultra® is a unique and proprietary dietary fiber formulation, shown to significantly reduce body weight in a human clinical study. The main constituent in LipoSan Ultra® is chitosan, which has been modified and optimized to enhance its
solubility in stomach acid and fat binding performance.

Produced in Iceland by combining fresh and high quality raw materials and years of manufacturing experience, LipoSan Ultra® is a patented product that also contains succinic acid, a GRAS approved food additive.

LipoSan Ultra® is available in a wide range of formats for every type of customer. Please check our products page for more information.

How does LipoSan Ultra work?

Patented Primex technology makes LipoSan Ultra® bind with dietary fat in the stomach and separate it from the digesting food. This results in an emulsion that forms a gel around the dietary fat and prevents it from being absorbed in the body.


A clinical study assessing LipoSan Ultra® showed very positive results. In a double blind placebo-controlled study a significant weight loss was observed in the group taking regular doses of LipoSan Ultra®. Read the details and look at the data in our scientific documentation section.
