What are liposomes?
Liposomes are: “spherical-shaped vesicle that is composed of one or more phospholipid bilayers, which closely resembles the structure of cell membranes. The ability of liposomes to encapsulate hydrophilic or lipophilic drugs have allowed these vesicles to become useful drug delivery systems.”
The payload is entirely protected and makes it intact to the bloodstream. Sublingual can only deliver up to 30% to blood, with the rest being digested same as other products.
So, Liposomes are 3x more effective than sublingual. They are costly to manufacture, but are being used more in more in supplements.
