Why This Matters
What you eat during cancer shouldn't be guesswork.
Cancer drugs target specific genes and molecular pathways. Many everyday foods and supplements act on those same targets — sometimes reinforcing your treatment, sometimes working against it.
Most patients are never told this. Most oncologists don't have time to cover it. We built addon so you don't have to guess.
Some foods can interfere
A supplement you take daily might reduce the effectiveness of your chemo — and you'd never know.
Some foods can help
Certain compounds in everyday foods act on the same pathways your treatment targets — reinforcing its effect.
Your nutrition should be informed by the same science that guides your treatment.
That's what addon does.

In remission or recovery and want to eat in a way that supports your long-term health. addon shows you what the research says.
High Risk
