A dietary supplement composition having a dispersion including a plurality of liposomal vesicles, includes an active ingredient, phospholipid contained in the liposomal vesicles, and a coating material. The active ingredient is incorporated within the liposomal vesicles having a barrier coating of the coating material including one of a biopolymer, polyethylene glycol, chitosan and a combination thereof. The coating material is free flowing in the dispersion such that the liposomal vesicles are surrounded by the coating material without being attached to the liposomal vesicles and without forming part of the liposomal vesicles and without affecting weight of the liposomal vesicles. The dispersion is filtered using a tangential flow technique, which washes out outer periphery of liposomal vesicles for removing inactive ingredients contained outside the liposomal vesicles without washing out the coating material surrounding the liposomal vesicles. The dietary supplement composition may be incorporated in gummies, chocolates, atomizers or powders.
