High-Dose Vitamin C IV Infusion

High-dose intravenous vitamin C delivers up to 7.5 g of ascorbic acid directly into the bloodstream — a concentration unreachable through oral supplementation due to intestinal absorption limits. Administered by medical personnel over 45 minutes at K+Clinic's Prague 5-Smíchov site, IV vitamin C may support immune function, accelerate recovery from illness or intensive training, and provide antioxidant protection during periods of high physical or psychological stress. Single sessions cost 1,100 Kč (discounted); 3-infusion courses 2,900 Kč; 5-infusion courses 4,500 Kč.

Vitamin C is an essential water-soluble antioxidant involved in collagen synthesis, immune cell function, iron absorption, and protection against oxidative stress. While the upper tolerable intake level for oral supplementation is approximately 2 g/day (limited by gastrointestinal absorption), intravenous administration bypasses the gut entirely — allowing plasma concentrations 30 to 70 times higher than can be achieved orally. At K+Clinic, high-dose IV vitamin C is administered by medically trained staff using a standardised protocol: up to 7.5 g of pharmaceutical-grade ascorbic acid in a saline or glucose carrier solution, infused over 45 minutes via a peripheral cannula. The slow infusion rate is important for tolerability and maintaining stable plasma levels throughout the session. In the context of wellness and recovery medicine, high-dose vitamin C is most commonly sought by people experiencing frequent illness, fatigue following viral infection, intensive athletic training loads, high work-related stress, or poor dietary intake. Athletes undergoing heavy competition schedules use IV vitamin C to support recovery speed and reduce oxidative damage from exertion. Post-viral fatigue — including after respiratory infections — is another common indication, as high-dose vitamin C may help restore depleted tissue stores more rapidly than oral supplementation. The clinic offers three formats: a single infusion (1,100 Kč, discounted from 1,300 Kč), a 3-infusion course (2,900 Kč), and a 5-infusion course (4,500 Kč). The standard recommended protocol for immune support or recovery is 3–5 infusions at weekly intervals. Contraindications include glucose-6-phosphate dehydrogenase (G6PD) deficiency, active kidney stones (particularly calcium oxalate), and known hypersensitivity to the formulation. The clinic's medical staff screen for these before commencing treatment.
