What is liposomal curcumin?

Liposomes are spherical vesicles composed of 2 layers of phospholipids that can carry both hydrophobic (water-insoluble) and hydrophilic (water-soluble) compounds. They are typically used in formulations where the active ingredient is insatiable or has low bioavailability, such as curcumin. Animal studies have shown that liposomal curcumin may be more effective compared to standard curcumin formulations.^[1] These formulations are typically more expensive and although results seem promising, data on humans is not available.
