Empirical Labs has mastered liposomal technology using natural Phosphatidylcholine liposomes as a delivery method for Vitamin C. We believe that each and every component of our products must be as health building as possible. Current literature has shown that hydrogenated liposomes strongly increase LDL (bad) cholesterol levels while natural non-hydrogenated phosphatidylcholine was shown not to alter cholesterol levels in primates. Our choice was easy. We are currently the only company to use all natural non-hydrogenated phosphatidylcholine for our delivery system with a claim put right on the label! We take great care to process our liposomes properly in order to generate properly structured spherical liposomes in our product. If the structure is not there, they are not liposomes.
