Liposome dosage forms began to be used as drug carriers in 1971 by Rymen and others, and are gradually being widely used in current pharmaceutical dosage forms. According to the different structures of liposomes, Joyous divided liposomes into three categories.
The first type of liposome, Unilamellar or Single Compartment Liposomes, has a spherical diameter of ≤25 μm. Generally, this liposome is used for water-soluble single components. It will be encapsulated by the lipid bilayer, while the fat-soluble component is dispersed in the bilayer. In the molecular layer, general unilamellar liposomes are produced by ultrasonic machines.
The second type of liposomes, Multilamellar or Multiple Compartment Liposomes, have a spherical diameter of ≤10 μm. They are separated by a multi-layered lipid bilayer and a water film containing water-soluble active ingredients, forming a heterogeneous polymer. The fat-soluble active ingredients are Still dispersed in several bilayers.
The third type of liposome, Macrovesicle, has a spherical diameter of about 0.13±0.06 μm and is unilamellar. It can encapsulate 10 times more active ingredients than single-chamber liposomes.
The wrapping principle of liposomes is actually very simple. The simplest liposomes use the bilayer structure formed when phospholipids are naturally dispersed in water for liposome wrapping. Depending on the active ingredients, the structure is matched with different proportions of cholesterol and Phospholipids and some stabilizers that fix the structure encapsulate the active ingredients into the bilayer. The structure will be similar to the surface structure of human cells, so it will be more convenient for penetration. The structural shape can be adjusted by the final extrusion step during liposome production to adjust the particle size to correspond to the targeting of different cells and the specificity of the human body. A network of exclusion. (The phospholipid can be soy phospholipid or sunflower phospholipid. Generally, Joyous will use soy phospholipid with 20% phosphatidylcholine. If the customer is concerned about allergens, we will also use sunflower source, but of course the price is more expensive)
At present, the structure of liposomes is slowly beginning to diversify, but it remains the same. We only need to choose the appropriate direction to select and distinguish.
In addition, liposomes mostly appear as pharmaceutical dosage forms. The liquid form when used in food is not very suitable for the environment of supplements. The adhesion of the liquid during processing will greatly increase the loss, and whether it is stored, transported or combined with other ingredients It is extremely inconvenient at times. Joyous has made a powder dosage form in this regard. Although the encapsulation rate and actual effect will be smaller than the liquid liposome structure, it is still better than using the most original raw materials, and the price is cheaper. Our current price is FOB Shanghai 14 USD/kg, hope this will be helpful to your company.

Product information
What is Liposomal Vitamin C powder?
Liposomal Vitamin C is an enhanced form of the vitamin designed for better nutrient absorption and utilization in the body. Liposomes are small spherical cells with an outer layer composed of fatty acids called phospholipids derived from sunflower or soybeans. Liposomes also have an inner compartment composed of water and water-soluble active ingredients. Water-soluble ingredients such as vitamin C are protected within internal compartments through the liposome structure.
The main advantage of liposomal vitamin C is improved absorption. There is a threshold for the ability of our intestinal cells to take in higher doses of vitamin C. This is why taking higher doses of vitamin C can lead to excessive gas and/or diarrhea. The bioavailability of liposomal vitamin C is significantly higher than that of regular vitamin C, almost twice as much. Oral liposomal vitamin C is often recommended as an alternative to intravenous (IV) vitamin C.

Why do we choose Joyous liposomes among the liposome series products?
The first liposomes we made were liquid liposomes with trace elements iron, and later we started researching vitamin C. When we started getting many customers to buy them, we found that liquid liposomes were too viscous because of the high viscosity of phospholipids. It causes a lot of losses during production and use, and when liquid liposomes are used in final products, they are in a single form, so we started research on liposome powders. Currently, we have three directions. The first is price. The cheapest crude liposomes, the second is a lyophilized form of liquid liposomes, and the third is a reconstituted liposome powder that changes back into liposomes when it is in water.
