Why is Vitamin C Bio availability important?
Infusion of vitamin C, via arteries or veins, has been reported to decrease oxidative stress 1–3 and, in many instances, improve physiological function in adult humans.
Reported benefits of Liposomal Vitamin C
Reported beneficial effects include, but are not limited to, increased baroreflex sensitivity, improved endothelial function and vascular conductance,augmented inotropic and thermogenic response to beta-adrenergic stimulation, decreased systemic inflammation and reduced fluid requirements during recovery from thermal injury, fatigue resistance in clinical populations, and cancer cell-specific toxicity.
Liposomal Vitamin C compared to Current Vitamin C
Compared with vitamin C infusion, oral vitamin C administration is typically less effective, in part due to inferior vitamin C bio-availability
Following ingestion, subsequent vitamin C bioavailability is largely determined by rates of intestinal absorption and further influenced by renal reabsorption and excretion.Sodium-dependent vitamin C transporters 1 and 2 are the primary mediators of intestinal absorption and renal re-absorption.
Sodium-dependent vitamin C transporter 2 also facilitates entry of vitamin C into most metabolically active cells and tissues.
Direct infusion of vitamin C bypasses the dependency on intestinal absorption; thus, high circulating concentrations are achieved soon after administration.13 Infusion of vitamin C is an impractical mode of administration for most of the general public and also carries a risk of infection, discomfort, and phlebitis. Accordingly, an alternative mode of effective vitamin C delivery is of obvious interest. In this regard, oral consumption of vitamin C encapsulated in liposomes may hold promise
