Immune Boost IV

A high-dose immune support IV infusion combining vitamin C, zinc, B-vitamins, and immune-modulating nutrients — delivered by a registered nurse at your hotel, home, or office in the Lisbon area.

The Immune Boost IV is formulated to support immune function during periods of increased demand — travel, seasonal illness exposure, post-illness recovery, or general immune system maintenance. The infusion delivers immune-relevant nutrients at concentrations that would be difficult to achieve through oral supplementation alone. High-dose vitamin C is the centrepiece of the formula. At intravenous concentrations, vitamin C reaches plasma levels 30-70 times higher than the maximum achievable through oral intake, providing antioxidant and immune-modulating effects that oral supplementation cannot replicate. Zinc supports multiple aspects of immune cell function and is commonly depleted during infection. B-vitamins support the metabolic processes that immune cells depend on for rapid proliferation during an immune response. This treatment is frequently requested by travellers arriving in or departing from Lisbon who want proactive immune support, patients in the early stages of cold or flu symptoms, and those recovering from illness who want to accelerate their return to baseline. It can be combined with the Athletic Recovery or The Works infusions for patients who want both immune and physical recovery support. All treatments are delivered at the patient's location by a registered nurse from the Drip IV Portugal team, operating under ERS registration E172088 and the medical direction of Dr. Rita Marques.
