High-concentration intravenous nutrient therapy used as a supportive, integrative part of your cancer care, coordinated by your naturopathic doctor in Ontario.
When vitamin C is taken orally, its absorption is strictly limited by the digestive tract, capping the concentrations that can actually reach your cells. Intravenous (IV) administration completely bypasses these digestive barriers, safely delivering high-dose vitamin C directly into your bloodstream to achieve levels impossible through oral supplementation alone.
At these elevated, clinical concentrations, vitamin C transitions into a powerful metabolic and systemic support tool for oncology care. It is thought to exert its action through targeted mechanisms, generating oxidative stress that is selectively toxic to cancer cells while remaining non-toxic to healthy cells, lowering systemic inflammation, interfering with tumor blood vessel formation, and supporting immune function by increasing specific white blood cells.
High-dose IV vitamin C is an evidence-based adjunctive therapy designed to work safely alongside conventional oncology timelines, such as chemotherapy and radiation. It can be used as a supportive and integrative protocol to enhance your overall care and resilience, and it is never used in place of the care your oncology team provides.
JOSIE is a virtual naturopathic clinic, so the clinical thinking behind your protocol happens in your online appointments, where your naturopathic doctor reviews your oncology timeline, current medications, and lab results. When an infusion is appropriate, the in-person sessions take place at our partner naturopathic IV lounge in Etobicoke, Toronto.
Clinical research demonstrates that high-dose IVC is generally safe and well-tolerated, with a primary benefit of managing cancer-treatment-related side effects. It helps significantly reduce deep fatigue, pain, nausea, and appetite loss.
Early research suggests that IVC may provide benefit for cancer outcomes, including tumor response and survival, when paired with standard treatments, particularly for advanced pancreatic, ovarian, and certain colorectal and lung cancers.
Starting protocols early helps build up nutritional reserves, manage treatment-induced depletion, and establish baseline cellular resilience before and during your regimen.
A G6PD blood test is required before booking, alongside careful clinical screening of general markers such as kidney function and electrolytes.
Dosing and timelines are tailored to you and your oncology plan. A typical course looks like this:

Thyroid healthThe hypothyroidism symptoms in women that get missed most often are fatigue that sleep doesn't fix, brain fog, low mood, thinning outer eyebrows, constipation, muscle aches and heavier periods. They're easy to miss when only TSH is tested, or when labs are "normal" but not optimal.

Integrative cancer careFor most cancers, no, not in any meaningful way. A biopsy needle can occasionally carry a small number of cells along its path, but true tumor seeding is extremely rare, and biopsies have not been shown to worsen survival in common cancers like breast cancer. The bigger risk, in almost every case, is delaying the diagnosis.

IV therapy & nutrientsIV nutrient therapy isn't a replacement for medical treatment — it's a support tool. Used well, it corrects deficiencies faster than oral supplements can, bypasses a gut that's struggling to absorb nutrients, and helps the body tolerate treatment better. Used badly, it's an expensive drip with no real plan behind it. The difference is whether it's targeted to what your body actually needs.
