High-Dose IV Vitamin C in Frisco, TX

High-dose intravenous vitamin C is one of the most studied and most misrepresented services in this field. We offer it as complementary supportive care, alongside — never instead of — conventional medical care, and only after labs and a physician or nurse practitioner consultation. Here is what the research actually says.

Featured ingredients

Ascorbic Acid, 15g to 100g

Available at 15g ($199), 25g ($239), 50g ($289), 75g ($319) and 100g ($339). Laboratory work and a doctor or nurse practitioner consultation are required before your first infusion — this is not optional and it is for your safety.

At a glance

What this session offers

A plain description of what is in the bag and what happens while you are here.

Pharmacologic rather than nutritional dosing

The IV route reaches plasma concentrations that oral dosing physically cannot.

Full screening protocol

G6PD status, renal function and stone history are checked before your first infusion.

Physician or NP consultation included

Required before you begin, and the right place to discuss coordination with your oncology team.

A range of dose levels

So the program can start conservatively and be adjusted clinically.

The science

What the research actually shows

We would rather tell you where the evidence is strong, where it is thin, and where it simply does not exist yet.

Why the IV route changes everything here

Oral vitamin C is tightly regulated by intestinal absorption and renal excretion, with plasma concentrations capped below roughly 300 micromol/L; above 1 g/day oral absorption falls below 50%. Intravenous administration bypasses this. The National Cancer Institute's PDQ summary reports concentrations up to 20 mmol/L — roughly a 60-fold difference, sustained for several hours.

What happens at those concentrations

At pharmacologic rather than nutritional levels, ascorbate acts as a pro-oxidant, generating extracellular hydrogen peroxide. Preclinical work implicates labile iron and hydrogen peroxide in selective effects on some cell types. This is a laboratory mechanism.

The state of the clinical evidence, stated plainly

Clinical work is confined to small phase I and phase II trials. NCI PDQ explicitly states these studies have several limitations due to lack of rigour in trial design. Some reported improved quality of life and reduced chemotherapy-related toxicity. No phase III efficacy has been established, and IV vitamin C is not FDA-approved for any oncology indication. It is not a cancer treatment, and we will not present it as one.

The safety data

A scoping review of 74 studies covering 2,801 patients at a median 22.5 g/day found adverse event rates comparable to placebo across nine double-blind randomised trials, while cataloguing rare serious events — which is precisely why we screen.

Who commonly considers this: People exploring complementary supportive options, most often in coordination with an oncology team, and anyone interested in high-dose vitamin C who is willing to complete the screening protocol.

Safety, screening & contraindications

G6PD deficiency screening before the first infusion is mandatory. Pharmacologic ascorbate can cause acute haemolysis in G6PD-deficient individuals.
Renal function and kidney stone history are checked. Ascorbate is metabolised to oxalate, and oxalate nephropathy has been reported. Baseline creatinine and eGFR are required with ongoing monitoring.
GLUCOMETER INTERFERENCE — high plasma ascorbate interferes with glucose-oxidase meters and produces falsely elevated capillary glucose readings. If you use insulin, this is dangerous: you could dose against a false high. Use laboratory plasma glucose during and for several hours after infusion, and tell us you are diabetic.
Coordinate with your oncologist. NIH ODS advises patients on chemotherapy to consult their oncologist before high-dose vitamin C, and preclinical data show oxidised vitamin C reduced the cytotoxicity of several chemotherapy agents in cell studies. Also caution with heart failure (fluid volume) and hemochromatosis.
