Vitamin C plays an important role in immune, skin, gum and brain health. When the diet is not satisfying enough, or the body's oxidative stress increases, additional vitamin C supplements can help us better maintain health. What many people don't realize about vitamin C supplements is that they are not well absorbed-most people excrete them from their bodies after ingestion. In order to improve the absorption rate, there is an important strategy, which is to use liposomes to construct "liposome vitamin C".
What is liposomal vitamin C?
Liposomes are small lipid vacuoles similar to cell membranes; their exterior is composed of a double-layered phospholipid layer, and their interior cavity can be used to transport substances. When liposomes carry vitamin C, liposome vitamin C is formed. Therefore, liposome vitamin C is nothing more than a film on the outside of vitamin C. So what's the use of putting this film on? The answer is: to increase absorption.
Liposomal vitamin C is an alternative to the standard form of vitamin C tablets (also known as ascorbic acid). This type of vitamin C is not in the typical tablet, pill or powder form, but delivers the vitamin inside tiny fat droplets. The goal of taking liposomal vitamin C is to increase levels more effectively than other "standard" supplements. Even if someone takes a concentrated amount of vitamin C in supplement form, plasma (blood) vitamin C levels usually remain relatively low because only a small portion is actually absorbed.
Liposomes refer to a drug or supplement formulation that contains the active drug inside tiny, fat-like particles called phospholipid bilayers. This form is generally more easily absorbed by the body and allows more of the supplement/drug to reach specific cells or areas of the body.
The fats/lipids used in liposomal supplements are synthesized from cholesterol and other forms of fats. These are the same fats that form cell membranes (the outside of cells that "seal them"). Several scientific studies have found that liposomal vitamin delivery systems help get more of the vitamin into the bloodstream than "unencapsulated vitamin C supplements" (more traditional fat-free supplements). Liposomal vitamins offer many advantages over most other oral forms of supplements, including increased intracellular delivery and high bioavailability and absorption.
The difference between VC liposomes and non-VC liposomes
Theoretically speaking, the absorption rate of liposomal vitamin C will be better than that of ordinary vitamin C. But what is the actual effect? We still have to look at clinical studies.
In order to verify the effect of liposomal vitamin C, the researchers recruited 24 healthy subjects for the trial. The subjects were randomly divided into two groups and tested two different forms of vitamin C before and after. All tests were performed under fasting conditions, using a dose of 1 g of vitamin C per test. Before and after the test, the researchers conducted a total of 21 blood draws to determine the vitamin C content in the blood.
Experimental results show that at the same dose, liposomal vitamin C can reach a peak blood drug level that is 2.4 times that of ordinary vitamin C. In terms of overall bioavailability, the utilization rate of liposomal vitamin C is approximately 1.77 times that of ordinary vitamin C.
So the conclusion is that liposomal vitamin C has a higher absorption rate than ordinary vitamin C. At a dose of 1g, the bioavailability of liposomal vitamin C is approximately 1.77 times that of ordinary vitamin C.
Other advantages of Vc liposomes
1. High bioavailability
Some research suggests that encapsulated nutrients (or drugs) are often better protected from the damaging effects of stomach acid and the harsh environment of the gastrointestinal tract, which can destroy nutrients before they are actually absorbed. Micronized encapsulation may increase transmucosal (oral) uptake and intracellular delivery better than some other formats.
2. Non-invasive and easy to use
Taking liposomal vitamin C to boost blood levels is a convenient option compared to injections, which can be costly, painful and sometimes risky due to the risk of contamination. This type of vitamin C can also be stirred into a liquid, making it a good option for those who have difficulty swallowing supplements. Two other advantages include that it can be adjusted in incremental doses and can be taken in low doses, which may limit side effects.
3. Reduce acid damage to the stomach
Regular forms of vitamin C are acidic, which is not so friendly to people with sensitive stomachs.
In this case, non-acidic esterified vitamin C can be an option. The main component of liposomes, phospholipids, can protect and shield the active ingredients, avoid the body's powerful filtration system and safely transport them into the blood. It can also reduce the osmotic side effects of certain high-dose vitamins and minerals.
