Mega C Antiviral

Mega-C Anti-Viral IV Therapy is a high-dose vitamin C infusion designed to support the body's response to viral illness, immune challenges, and chronic infection. Delivered intravenously — bypassing the gut absorption limit — Mega-C reaches blood concentrations far above what's possible from oral supplementation.

Why high-dose vitamin C?

Oral vitamin C is limited by gastrointestinal absorption — most people can absorb at most 500–1,000 mg in a sitting. IV administration bypasses this limit, allowing therapeutic doses (often 25–75 grams or higher under medical supervision) to circulate at concentrations that simply aren't achievable orally.

At these levels, vitamin C acts not just as an antioxidant but as a pro-oxidant in pathological cells, generating hydrogen peroxide that targets viruses, bacteria, and damaged cells while sparing healthy tissue.

What we use Mega-C for

We use Mega-C IV as part of integrative care plans for:

Acute viral illness — flu-like illness, post-COVID recovery, herpes flare-ups, mononucleosis
Chronic viral burden — Epstein-Barr, CMV, chronic Lyme co-infections
Immune support during high-stress periods — travel, sleep deprivation, post-exposure
Adjunctive integrative cancer care (in coordination with oncologist)
Acute respiratory infection support

The Benefits

A typical Mega-C session runs 60–90 minutes. We start with a baseline G6PD test (a blood draw) before your first high-dose IV — this enzyme deficiency is the main contraindication for high-dose vitamin C. Once cleared, doses are scaled up gradually session-by-session based on your response.

The IV is delivered through a soft catheter in the arm; most patients read, work, or rest during the infusion. Side effects are uncommon at properly dosed protocols — mild thirst is the most common observation.

Why Choose Upper Room Clinic for Mega-C IV

Mega-C is more than a high-dose vitamin C drip — it requires baseline screening, careful dose titration, and integration with the rest of your care. At Upper Room Clinic in Toronto:

Mandatory G6PD screening before your first high-dose IV — this enzyme deficiency is the main contraindication
Physician-led titration — doses are scaled gradually session-by-session based on your response
Integrated infusion suite — Mega-C is delivered alongside other IV protocols, regenerative therapies, and integrative oncology programs
Patient-centred care — protocols match your reason for receiving it (acute illness, chronic infection, post-cancer support)
Whole-person approach — vitamin C IV is one tool, not the whole plan; we look at sleep, nutrition, infection burden, and immune signalling together
Convenient Toronto location at 1849 Yonge Street, with Oakville coming soon, serving the GTA

Patients choose us because we combine evidence-based dosing with a deeply personalized approach to immune support.

What to Expect

Every IV at Upper Room is physician-guided. Here's how getting started works.

1. Book your consultation

Your first step is a 15-minute Wellness IV Consultation ($175). The fee is waived if you go ahead with your drip within a week. If you're being treated for a complex condition such as autoimmunity, cancer or MCAS, you may be asked to complete our 30- or 60-minute Functional Medicine Consult ($350 / $600) instead.

2. Bloodwork, if needed

Vitamin C drips of 25g or more, IV ozone therapy and EBOO all require a G6PD blood test first. Our doctor may also request bloodwork before any other IV at her discretion. Your safety and wellbeing are our top priority.

3. Your infusion

Once you're cleared, we book your drip at our Toronto or Oakville clinic.
