Biological treatment

Biological treatments are supportive regimens that can sometimes fall under immunotherapy due to their nature, and work by harnessing the body's natural immune system or targeting precise molecular pathways involved in cancer growth.

01 / How it works

How Biological Treatment works

Vitamin C is one of the biological treatments used at Verita Life. When taken at a physiological dose (orally) it acts as an antioxidant - donating electrons, scavenging for free radicals and supporting normal cell function and collagen/immune biology. When taken at a pharmacological dose (intravenously) it acts as a pro-oxidant, generating sustained hydrogen peroxide that is selectively toxic to tumour cells rather than systemic oxidative stress.

High dose Vitamin C infusions result in high concentrations of this hydrogen peroxide. These high concentrations damage cancer cell’s DNA and mitochondria and have a sort of destabilising effect that helps break down the cells and destroys the cancer. Alongside other cancer-fighting therapies, High Dose Vitamin C injections can significantly reduce the effect of cancerous cells.

When this treatment may be considered

Ask which substance is proposed, its treatment goal, and the evidence relevant to your diagnosis. Kidney function, other medicines, and specific blood conditions may affect whether an infusion is appropriate.
