Reactive care matters when you're already sick — but there's also a case for building immune support into your routine ahead of time.
Oral vitamin C absorption has a ceiling — beyond a certain dose, your gut simply can't absorb more, and excess amounts often cause digestive discomfort. IV administration bypasses this limit entirely, allowing for meaningfully higher doses to reach your bloodstream directly.
This is one of the clearest examples of why route of administration matters for certain nutrients.
Zinc is involved in immune cell development and function. It's one of the more researched micronutrients when it comes to immune support, particularly around reducing the duration of upper respiratory symptoms when supplementation starts early.
Rather than waiting until you feel something coming on, some people build a monthly or biweekly immunity drip into their routine starting in early fall, treating it as a proactive habit rather than a reactive treatment.
Many people also come in at the first sign of symptoms, since that's when supportive hydration and nutrients may help you feel more comfortable while your body fights off whatever's going around. This is a different use case than proactive routine-building, but both are common reasons people book an immunity drip.
