liposomal vitamin C (AronPharma)

Liposomal vitamin C is a formulation of ascorbic acid (vitamin C) encapsulated within lipid-based vesicles known as liposomes. This delivery system is designed to enhance the bioavailability and stability of vitamin C compared to conventional oral forms, as the liposomal structure protects the nutrient from degradation in the digestive tract and facilitates absorption across cell membranes. It is primarily used as a nutraceutical for antioxidant support, immune function, and addressing vitamin C deficiency. In clinical research, it is being investigated for its potential to enhance the efficacy of chemotherapy (e.g., in combination with ATR inhibitors like ceralasertib) by increasing intracellular concentrations and promoting oxidative stress-induced cell death, specifically through the activation of ferroptotic pathways in cancer cells.
