Liposomes are extremely tiny, spherical particles, which allows for fast absorption, starting in the mouth and continuing throughout the GI tract. Liposomes are made of phospholipids—the primary building blocks of cell membranes. Owing to this structure, liposomes bond easily with cell membranes to facilitate intracellular delivery of their nutrient cargo. Thanks to this enhanced delivery and absorption, nutrients delivered in liposomal form offer superior bioavailability and efficacy.
