Can Melatonin Help Cancer Treatment?

Dominic Brandy • October 13, 2026

Most people know melatonin as a sleep aid . Researchers have been asking a different question about it.

Melatonin is one of the supplements patients ask me about most often, usually for sleep. What gets far less attention is the body of research looking at what else it may be doing, and why that has drawn interest in the setting of cancer treatment.

In this short video I walk through what that research actually says, where it is strong, where it is early, and the questions worth bringing to your own oncologist.

Questions about your own case?

I do private virtual consultations, and we can talk through your health and your cancer journey together.
