Bangham, a biophysicist, studied colloidal lipid dispersions in order to mimic the structure and functionality of cell membranes and study their functionality.Īs long as the liposomes are constructed from similar materials to human cells they benefit over other delivery carriers due to their structural similarity to human membranes. In the early 1960s, there existed a trend for the study of the biophysical properties of colloidal systems that were composed of lipids and phospholipids with the goal of understanding the biophysical functions of cells. Depending on the preparation method, in combination with the physicochemical characteristics of their structural units, the dimensions of the liposomes range from nanometers to a few micrometers. Liposomes belong to the colloidal delivery systems of bioactive substances which possess the ability to transfer them and hence improve their effectiveness.
increase the absorption and the bioavailability in comparison to free and to other conventional pharmaceutical carriers (i.e.protect the active substance from oxidation and degradation in the acidic pH of the stomach,.Liposomes exhibit several advantages for the delivery of vitamin and food supplements:
The liposomal formulation allows for the higher absorption of its active substances and vitamins. VITAMIN D3 2500IU & K2 200mcg is a dietary supplement that contains vitamins D3 and K2 (as menaquinone-7).īoth of these vitamins in conjunction helps to maintain:
