Immunity IV Therapy in Seaport, Boston
Immunity IV Therapy delivered to the Seaport by a licensed registered nurse, or booked at either South Boston clinic — $279 — Defense.
Medically directed and founded by Olivia Kelly, NP, NP, RN — Licensed since 2003.
High-dose vitamin C and zinc given intravenously reach blood levels oral supplements cannot approach — which is why people book this at the first scratchy throat rather than after three days of it. The Seaport is conference and corporate territory: booth crews, launch weeks, and Saturday-morning recoveries after a night on Northern Ave. We serve the Seaport two ways: at our South Boston clinics on A Street and L Street, or with a licensed nurse dispatched to your address. The Seaport is our closest coverage area — walk-in at A Street or expect mobile dispatch in 45–75 minutes.

Benefits
Why patients choose Immunity IV Therapy in Seaport
IV-only vitamin C levels

Hydration while you are sick
Fever and poor appetite dehydrate you fast; a liter of fluid is half the benefit of this visit.
