Doctor's Formulas Vitamin D3 2500iu - Liposomal Formula Vitamin D3 Dietary Supplement, 150ml

Liposomal Formula VITAMIN D3 2500IU is a dietary supplement containing 2500 units of vitamin D3 (as cholecalciferol) which contributes to the maintenance of normal calcium levels in the blood and the normal state of bones. Liposomal formulation technology results in greater absorption and bioavailability of active substances and vitamins. Liposomes Liposomes belong to the colloidal dispersions of bioactive molecule transport systems which have the ability to transport them, improving their effectiveness. The dimensions of liposomes, depending on their preparation method and the physicochemical characteristics of their structural units, are in the order of nanometers to a few micrometers. Historically, in the early 1960s, there was a tendency to study the biophysical properties of colloidal systems that had a lipid and phospholipid composition, with the aim of understanding the biophysical functions of cells. The biophysicist AD Bangham studied lipid colloidal dispersions, to simulate cell membranes and study their functionality. Since liposomes are prepared from structural materials like those of our cells, they have advantages related to their 'friendliness' towards human tissues. They have the ability to transport lipophilic bioactive molecules that do not dissolve easily in aqueous media and therefore have absorption and bioavailability problems, e.g. vitamins, curcumin, etc., as well as water-soluble or amphiphilic molecules, are improved in terms of their dissolution rate and absorption through the gastrointestinal lumen. Liposomes can also transport bioactive substances and improve their penetration through the barriers of the gastrointestinal tract and are effective 'vehicles' for transporting bioactive molecules. Liposomal technology and especially the innovative technology of supramolecular phospholipid complexes with a lipid bilayer structure can improve the therapeutic efficacy of dietary supplements and are an innovation in this field, giving high added value to the final dosage form.
