Immune Support IV Therapy — Find Clinics Near You

Immune support IV therapy delivers a concentrated combination of immune-modulating nutrients directly into the bloodstream — most notably high-dose vitamin C, zinc, B vitamins, and the master antioxidant glutathione. Oral supplementation of vitamin C is capped at roughly 200mg of absorption per dose due to intestinal transport limits, but IV administration can deliver several thousand milligrams in a single session, achieving plasma concentrations impossible to reach through diet or pills alone.

The protocol is commonly used in three contexts: preventatively during cold-and-flu season or before high-risk travel, at the first sign of an oncoming illness to shorten its duration and severity, and during chronic stress or recovery from prolonged illness. Athletes use it ahead of competition, frequent travellers use it before long-haul flights, and many wellness clients schedule it monthly as part of a broader immunity-focused protocol.

While robust clinical evidence varies by indication, the underlying nutrients have well-established roles in immune cell function — vitamin C supports neutrophil and lymphocyte activity, zinc is required for T-cell maturation, and glutathione protects immune cells from oxidative stress. A typical immune drip combines all of these in one infusion.
