Vitamin C: Understanding its different forms and its assimilation
Therevitamin Cis an essential nutrient, involved in many biological processes. Its absorption and effectiveness in the body may depend on several factors, including its chemical form and method of administration.
Certain forms of vitamin C are more commonly used in supplementation, and each has unique characteristics that influence how the body processes it.
Characteristics of water-soluble vitamin C
Conventional vitamin C (ascorbic acid or ascorbate) is water-soluble, meaning it dissolves in water and circulates freely in the body.
It is absorbed in the small intestine and the body naturally regulates its levels: when needs are met, the excess is eliminated through urine.
This regulation involves:
- A daily intake requirement, because vitamin C is not stored sustainably in the body.
- Variable absorption, influenced by the amount ingested and individual needs.
Food is the main source of vitamin C, but specific situations may justify supplementation, particularly in cases of needs linked to lifestyle, oxidative stress (e.g. pollution) or a diet low in fruits and vegetables.
Liposomal vitamin C: an encapsulation technology
Liposomal vitamin C is an innovative form that encapsulates vitamin C in liposomes, structures composed of phospholipids. This technique is studied for its specific properties:
- Lipid encapsulation: Helps protect vitamin C during its transport in the body.
- Facilitating cell passage: Liposomes have a structure similar to cell membranes, which allows them to interact more effectively with certain cells.
- Tolerance studied: The lipid coating could limit direct contact with gastric acidity, which interests researchers on the digestive tolerance of this form.
Scientific studies suggest that the liposomal form plays a role in the body's ability to assimilate it.
