LIPOSOMAL VITAMIN C
Vitamin C is an antioxidant frequently used for the common cold due to its positive immunological response to help fight bacteria and viruses alike. It has the ability to neutralize free radicals that results from foreign invaders during illness, as well as stress. Vitamin C also supports adrenal function and plays a role in the production of the adrenal hormone epinephrine and norepinephrine, both of which are crucial for the body’s ability to handle infections and stressors.
Typically vitamin C is purchased in supplement form as ascorbic acid. This is very different than when consumed through food because ascorbic acid is the antioxidant wrapper that comprises a mere 5 percent of the total vitamin C complex when found naturally.
Vitamin C is typically found in citrus and is water-soluble, meaning it’s found in bodily compartments that are water-based such as the blood and within cells. It’s absorbed through the gut lining, and therefore re-emphasizes the importance of gut health to support the immune system.
When it comes to vitamin C absorption, bioavailability, and absorption matter. Ascorbic acid is filtered by the kidneys, and studies show that actual absorption levels range from approximately 70–90 percent of vitamin C is absorbed in moderate intakes of 30–180 mg/day. However, at doses above 1 g/day, absorption falls to less than 50 percent with the absorbed, unmetabolized ascorbic acid being excreted in the urine.
Liposomal vitamin C, on the other hand, is cleared from the blood and shuttled directly to cells. It is wrapped in essential phospholipids and is therefore absorbed in a manner similar to dietary fats. It is taken up by the lymphatic system with an estimated 98 percent efficiency. Once there, it moves from the lymphatic system into the bloodstream. As a result, liposomes deliver more vitamin C into circulation compared to traditional vitamin C supplements.
