Liposomal vitamin C
Liposomal Vitamin C is a phospholipid that carries a bioactive component at its core. You can think of it as a “Trojan horse” that takes a completely different path compared to normal vitamin C which you get from food and/or supplements.
Vitamin C transport
Vitamin C or ascorbic acid is a water-soluble molecule and is found in vegetables (such as bell peppers and broccoli) and fruits (such as berries and citrus fruits).
It can also be absorbed through supplements such as pure ascorbic acid.
In the small intestine, this ascorbic acid is absorbed by the intestinal villi. Once the villi are saturated in vitamin C, the excess vitamin C leaves the body along the large intestine.
Once ascorbic acid is absorbed by the villi, it uses the ‘Sodium depended Vitamin C CoTransporters’ (SVCT1, SVCT2) during its active form (ascorbic acid) and the Glucose Transporters (GLUT 1,2,4) when in its oxidized form (dehydroascorbate )  .
The kidneys strictly and closely monitor the concentration of ascorbic acid plasma in the blood. All other absorbed vitamin C will be filtered out of the blood by the kidneys and will leave the body through the urine.
At this time, liposomal vitamin C benefits.
What is a Liposome?
A liposome is a phospholipid, a unique molecule that is partially fat-soluble and partially water-soluble.
Liposomes are actually like our cells and have a cell membrane that lets nutrients in and out of the cell.
The cell membrane consists of a double layer of phospholipids (phospholipid bilayer). The fat molecules are both on the outside and inside of the cell membrane.
The water part is located in the middle of these 2 layers of fat molecules.
One could say that the cell membrane consists of a “fat circle” (outside), followed by a “water circle” in the middle, followed by a “fat circle” (inside).
All this then surrounds the cell nucleus and is the structure for every cell in our body.
The same phospholipids are used as the outer wall of a liposome vitamin C supplement. This double layered phospholipid creates a sphere around water
containing component (also called the aqueus): dissolved vitamin C. 
The Trojan horse
Because their outer walls mimic our cell membranes, liposomes can fuse with our cells when in contact with each other.
In this way they supply the vitamin C, which is the water-dissolved bioactive molecule in this structure, from their nucleus to the cell.
This unique delivery system provides a targeted method of getting nutrients into the bloodstream without being destroyed by the acids or digestive enzymes inside the stomach or digestive system.
Liposomal vitamin C does not depend on the slow SVCT-1 transporters like normal vitamin C, but is directly absorbed by the intestinal cells that allow them to enter the bloodstream directly.
As a result, liposomal vitamin C is absorbed much better compared to conventional vitamin C.
The best way to absorb vitamin C (apart from intravenous through the veins) is therefore via liposomal vitamin C.
