Immunity IV

A 45- to 60-minute intravenous infusion formulated to support immune function, combining high-dose vitamin C at 12 grams, zinc, B-complex vitamins, calcium, and magnesium with a 1,000 mg glutathione push at the end of the session. This protocol is designed to deliver immune-relevant micronutrients at concentrations above what oral supplementation typically achieves.

The Immunity IV at Biohackr Health delivers a concentrated combination of micronutrients selected for their roles in immune system function. The infusion runs for approximately 45 to 60 minutes and concludes with a separate glutathione push. The centrepiece of the formula is 12 grams of vitamin C — a dose well above the tolerable upper limit for oral intake, achievable only through intravenous delivery. At these concentrations, vitamin C may function as a pro-oxidant within specific cellular contexts while maintaining its broader antioxidant properties in plasma. Research has explored high-dose intravenous vitamin C in the context of immune support, though clinical applications vary and individual responses depend on baseline nutrient status. Zinc is included for its well-established role in immune cell development and function. Even mild zinc deficiency can impair immune response, making supplementation relevant for individuals with suboptimal dietary intake or increased physiological demand. B-complex vitamins support energy metabolism and red blood cell production — both relevant to immune function during periods of stress or illness recovery. Calcium and magnesium provide electrolyte balance and support neuromuscular function. Magnesium in particular is involved in hundreds of enzymatic reactions and is frequently depleted during periods of physical or psychological stress. The session concludes with a 1,000 mg glutathione push — a separate short injection of the body's primary intracellular antioxidant. Glutathione is synthesised naturally but can become depleted under oxidative stress, environmental toxin exposure, or heavy physical training. The push delivery method provides a concentrated bolus over a few minutes. The Immunity IV is popular during cold and flu season, before and after international travel, during periods of high work stress, and as part of recovery from illness. Clients also use it proactively when they feel the early signs of an immune challenge. The infusion is administered in a comfortable lounge chair with clinical supervision throughout. No fasting is required, and there is no downtime afterward. Some clients experience a mild warm sensation from the magnesium component, which is normal and resolves quickly.
