Liposomes are colloidal dispersions in bioactive molecules transport systems that have the transport capacity, improving their effectiveness. The size of the liposomes according to their method of preparation and the physicochemical characteristics of the structural units is of the order of nanometers to the order of a few micrometers.

Historically, in the early 1960s, there was a trend study of the biophysical properties of colloidal systems which have a recommendation lipid and phospholipid, in order to understand the biophysical functions of the cells. The biophysicist A.D. Bangham studied lipid colloidal dispersions, to simulate the cell membranes and to study their function.

Liposomes where prepared from structural materials such as those of our cells have advantages related to the 'friendly' to the human tissues. They have the ability to carry lipophilic bioactive molecules which are not readily soluble in aqueous media and therefore have absorption and bioavailability problems, e.g., vitamins, curcumin, etc. and the water-soluble amphiphilic molecules, improved on the dissolution rate and the absorption through the GI lumen.

The liposomes and can carry bioactive substances and improve the penetration of the barriers of the gastrointestinal tract and are effectively 'vehicles' transport of bioactive molecules.

Liposomal technology and especially the novel technology of supramolecular complexes of phospholipid in the lipid bilayer structure can improve the therapeutic efficacy of dietary supplements and are an innovation in the art, yielding a high added value to the final dosage form.
