B-Complex Vitamin Infusion (Revita)

An intravenous B-complex infusion using the Revita preparation — a pharmaceutical combination of B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B12 (cobalamin), and amino acids — delivered over 60–90 minutes at Doktor Brno's clinic in central Brno. IV delivery eliminates the GI absorption variability that limits oral B-vitamin supplementation, making it particularly relevant for patients with compromised absorption (thyroid conditions, liver disease, diabetes, post-antibiotic dysbiosis) or those presenting with fatigue, neurological symptoms, or dermatological signs of B-vitamin insufficiency. Sessions are conducted under physician supervision in a clinical setting on Masarykova.

B-complex IV infusion at Doktor Brno uses the Revita preparation, which delivers the full spectrum of water-soluble B vitamins — B1, B2, B3, B5, B6, and B12 — alongside amino acids as a co-infusion. Each of these vitamins plays a distinct and essential role in human metabolism: thiamine (B1) is critical for carbohydrate-derived energy production and nerve impulse transmission; riboflavin (B2) is a cofactor for FAD-dependent oxidation reactions; niacin (B3) participates in over 400 enzymatic reactions via NAD/NADH cycling; pantothenate (B5) is essential for coenzyme A synthesis; pyridoxine (B6) is required for amino acid metabolism, neurotransmitter synthesis (dopamine, serotonin, GABA), and haemoglobin production; cobalamin (B12) is indispensable for myelin sheath maintenance and red blood cell formation. The intravenous route is particularly valuable here because each of these vitamins depends on active transport mechanisms in the gut that can be compromised by a wide range of conditions: thyroid disorders alter gut motility and B12 absorption; liver disease impairs B-vitamin storage and activation; diabetes causes accelerated B1 and B6 excretion; prolonged antibiotic use disrupts the microbiome that contributes to B-vitamin synthesis; autoimmune gastritis (pernicious anaemia) blocks B12 absorption entirely. For patients in these groups, oral supplementation — even at high doses — may fail to correct deficiency, while IV delivery guarantees systemic delivery. At Doktor Brno, the infusion is prepared and administered by the clinical team over 60–90 minutes with medical supervision throughout. The physician reviews the patient's clinical context at the initial consultation to confirm the indication and assess for contraindications. Common presentations that benefit from this protocol include: peripheral neuropathy symptoms (tingling, numbness, weakness), chronic fatigue unresponsive to lifestyle interventions, stress-related depletion (B vitamins are consumed faster under psychological and physiological stress), skin and mucosal conditions with a nutritional component, and post-illness recovery where oral intake has been compromised. The Revita formulation's amino acid component provides additional support for protein metabolism and tissue repair, making it broader in scope than a pure B-vitamin preparation. Sessions can be booked individually at 1,000 CZK or as part of a package course. The clinic can advise on course structure and spacing at the initial consultation.
