1. Liposome Vitamin C

In addition to its water-soluble nature, vitamin C's formulation with fats, creating a liposomal formulation, enhances its absorption and utilization within the body. The typical breakdown of vitamin C in the stomach, where it may be influenced by the highly acidic environment of hydrochloric acid, poses a challenge for its effective absorption. To address this, the water-soluble vitamin C molecule is encapsulated within a liposome, creating a protective shield against stomach acid. This encapsulation ensures the safe passage of vitamin C to the small intestine, bypassing potential degradation in the stomach.

The release of vitamin C occurs in the small intestine, a location where most fat digestion takes place. Enzymes from the gallbladder and pancreas facilitate the breakdown of lipids, allowing for the controlled release of vitamin C. This strategic delivery system helps maximize the absorption of the nutrient and enhances its bioavailability.

Scientific research has demonstrated that liposomal vitamin C leads to higher circulating concentrations compared to other oral forms that lack the liposomal protection. The liposomal encapsulation method proves instrumental in preserving the integrity of vitamin C during its journey through the digestive system.

Liposomal vitamin C formulations may incorporate phospholipids derived from various sources, such as sunflower oil, palm oil, or soybean oil.
