Liposomes are produced in a liquid atmosphere. When liposomal formulations are dried, the structure of the liposomes can no longer be maintained, and the liposomes dissociate.  We conducted a bioavailability study that compared liquid and powder forms of vitamin C. This study proved that the bioavailability of the powdered liposomal form was as poor as a non-liposomal powder product. In comparison, the liquid liposomal vit. C had a very high bioavailability.  Our Business Development Team will be happy to explain this process in detail. Contact us
