Immune Boost IV Therapy in Myeongdong Seoul — High-Dose Vitamin & Antioxidant Infusion

High-Dose Intravenous Vitamin C and Immune Function

Vitamin C (ascorbic acid) is a water-soluble essential nutrient that plays critical roles in both innate and adaptive immune responses. At physiological concentrations, Vitamin C enhances neutrophil chemotaxis, phagocytosis, and microbial killing through reactive oxygen species generation. It also supports lymphocyte proliferation and natural killer (NK) cell activity. Oral supplementation is limited by saturable intestinal absorption via sodium-dependent vitamin C transporters (SVCT1), which cap plasma levels at approximately 220 µmol/L even with high oral doses. Intravenous administration bypasses this bottleneck entirely, achieving plasma concentrations of 1,000–5,000 µmol/L — levels that exert direct pharmacological effects on immune cells. Padayatty et al. demonstrated that IV Vitamin C achieves plasma concentrations 30–70 times higher than maximum oral doses, and these supraphysiological concentrations enhance hydrogen peroxide-mediated antimicrobial activity in extracellular fluid. Clinical studies at RE:BERRY Myeongdong use immune boost IV doses calibrated to each patient’s body weight and health status.

Glutathione: The Master Antioxidant in Immune Defense

Glutathione (GSH) is a tripeptide (γ-glutamyl-cysteinyl-glycine) that serves as the body’s primary intracellular antioxidant and a critical cofactor in immune cell function. Lymphocytes, macrophages, and dendritic cells all require adequate GSH levels to mount effective immune responses. Depleted glutathione impairs T-cell proliferation, reduces NK cell cytotoxicity, and diminishes macrophage phagocytic capacity. Intravenous glutathione supplementation rapidly restores intracellular GSH pools, particularly in patients experiencing oxidative stress from travel, poor sleep, or environmental exposures. The combination of IV glutathione with high-dose Vitamin C creates a synergistic antioxidant network — Vitamin C regenerates oxidized glutathione (GSSG) back to its reduced active form (GSH), while glutathione recycles oxidized Vitamin C (dehydroascorbate) back to ascorbic acid. This redox cycling amplifies the antioxidant and immune-supportive effects of both compounds beyond what either achieves alone. RE:BERRY Myeongdong’s immune boost IV protocol leverages this biochemical synergy.

Zinc and B-Vitamins in Immune Modulation

Zinc is an essential trace mineral required for the development and function of over 300 enzymes and transcription factors involved in immune regulation. Zinc deficiency — common in travelers due to poor nutrition, stress, and alcohol consumption — impairs thymic function, reduces T-cell numbers, and weakens mucosal barrier integrity. IV zinc supplementation at physiological doses (5–10 mg elemental zinc) rapidly restores zinc-dependent immune pathways. B-complex vitamins (B1, B6, B12) serve as essential cofactors in energy metabolism and immune cell synthesis. Vitamin B6 (pyridoxine) is particularly important for lymphocyte maturation and antibody production. The comprehensive immune boost IV formula at RE:BERRY Myeongdong combines these micronutrients with Vitamin C and glutathione for multi-pathway immune activation that addresses the complex nutritional deficits common in international travelers.
