The Claim

The combination of vitamin C and the ROS-responsive prodrug FAN-NM-CH3 induces significantly greater DNA damage in cancer cells (up to 75% increase in comet tail DNA%) compared to either agent alone, and this damage is reversed by catalase, confirming that hydrogen peroxide-mediated prodrug activation is the primary driver of genotoxicity.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

When vitamin C and the prodrug FAN-NM-CH3 are used together, they cause a measurable increase in DNA damage in cancer cells, up to 75% higher than when either is used alone, and this damage is eliminated when catalase is added, indicating hydrogen peroxide is required for the prodrug to activate.

See the scientific wording

The combination of vitamin C and the ROS-responsive prodrug FAN-NM-CH3 induces significantly greater DNA damage in cancer cells (up to 75% increase in comet tail DNA%) compared to either agent alone, and this damage is reversed by catalase, confirming that hydrogen peroxide-mediated prodrug activation is the primary driver of genotoxicity.

Why this might work

Vitamin C creates hydrogen peroxide outside cancer cells, which enters them because cancer cells cannot break it down well. Inside, the hydrogen peroxide triggers a special drug to release a poison that breaks DNA. At the same time, iron in the cancer cells turns the hydrogen peroxide into an even more destructive force that shreds DNA further. Normal cells break down the hydrogen peroxide and have little iron, so they stay unharmed.

  1. Study: Exploiting vitamin C as a prooxidant to activate ROS-responsive prodrugs for potent and selective tumor killing

    Adding vitamin C to this special drug makes it much better at killing cancer cells by creating more harmful oxidative stress inside them — and it doesn’t hurt healthy cells. When they used both together, tumors disappeared completely and didn’t come back.
