The attraction of using liposomes to deliver nutrients, supplements and drugs into the body is that they are easily absorbed by the gastro intestinal tract and in so doing the additional encapsulated molecules are absorbed at the same time.
This overcomes the barrier that many products face, by effectively being absorbed into the body. The body will often break down many complex molecules before they are absorbed or will just not readily absorb them and so absorption levels are reduced.
Liposomes are easily absorbed so the products encapsulated by liposomes achieve much higher blood dosage levels than found in non-encapsulated products such as traditional tablets or oils. This is one of the many benefits that is shown in our liposome research.
Our knowledge is our power
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.
