Liposome Encapsulated Nutrients
What are Liposomes?
Liposomes are bilayer (double-layer), liquid-filled bubbles made from phospholipids. Over 50 years ago, researchers discovered that liposome-encapsulated nutrients were protected and could be used to deliver these agents into the body and even into specific cells of the body.
The bilayer structure of liposomes is nearly identical to the bilayer construction of the cell membranes surrounding each of the human body cells. This occurs because of the unique composition of phospholipids. The phosphate (source of "phospho" in phospholipid) head of phospholipids is hydrophilic — it loves water — whereas the fatty-acid tails (lipids) are hydrophobic — they hate water.
When phospholipids find themselves in a water-based solution, the hydrophobic tails quickly move to distance themselves from the liquid just like oil separates from vinegar. So, as all the tails turn inward and all the heads turn toward the liquid, they form a double-layered membrane.
The picture represents a phospholipid molecule showing a phosphate head (blue) and the fatty acid tails (yellow).
This liposome cutaway diagram shows how phospholipids' tails turn inward to form a bilayer membrane and encapsulate a nutrient.
Although research has not clearly shown how the nutrients in a liposome are released, there are many theories. One theory suggests that the phospholipids are processed in the liver as fats and that this process releases the nutrient. Another theory proposes that cells all over the body, hungry for phospholipid materials to repair cell membranes and other cellular structures, "steal" these materials from the liposome allowing their contents to leak out.
Quite possibly, both processes occur. In any case, the therapeutic value and greatly increased delivery of liposome-encapsulated nutrients and drugs have been scientifically confirmed countless times. At present, liposomes are the most bioavailable
oral way to deliver nutrients.
