Immunity Boost Max IV

A 60-minute high-dose immune support infusion combining vitamin C, zinc, glutathione, and B vitamins at concentrations designed to support the immune system during periods of increased demand or recovery.

The immune system depends on adequate micronutrient status to mount effective responses against pathogens and manage inflammatory processes. Several key nutrients — particularly vitamin C, zinc, and glutathione — play direct roles in immune cell function, and their requirements increase during periods of infection, stress, or recovery. The Immunity Boost Max IV delivers these nutrients at therapeutic concentrations via intravenous administration. High-dose vitamin C supports multiple aspects of immune function, including the production and activity of white blood cells, the maintenance of epithelial barriers, and antioxidant protection against the oxidative burst generated during immune responses. Zinc is essential for the development and function of natural killer cells and T lymphocytes. Glutathione — the body's most abundant intracellular antioxidant — protects immune cells from oxidative damage and supports their proliferative capacity. B vitamins contribute to the energy metabolism that immune cell activation demands. This is Qualevita's most comprehensive immune-support infusion, positioned above the standard Immunity Boost IV for individuals seeking maximum support during cold and flu season, while recovering from illness, or when travelling frequently and exposed to elevated pathogen loads. The treatment is administered at any of the three Amsterdam locations and pairs well with the Vitamin D and Vitamin C add-on shots for additional immune support.
