Liposomes for food supplements are made from lecithin-extracts rich in phospholipids.
When mixed with water, phospholipids form microscopic tiny vesicles with a central void encapsulating water and active ingredients dissolved in the water. Examples of such actives can be Vitamin C or Vitamin B12 which we would like to be absorbed more easily into the body. Whilst hydrophilic molecules can be held within the encapsulated water, hydrophobic chemicals can be dissolved into the membrane itself and in this way liposomes have the ability to carry both hydrophobic and hydrophilic molecules. Due to their unique properties liposomes are used for the formulation of drugs, food supplements and cosmetics.
