Cancer
Supplements studied for cancer.
Overview
Cancer supplement evidence is broad but condition-specific effects differ sharply. Melatonin has the largest trial base (22 studies) and may improve survival or tumor response when added to chemotherapy in some advanced cancers, though cancer type and regimen matter.
Vitamin D supplementation does not clearly lower overall cancer incidence, though some research suggests a modest effect on advanced or fatal cancers at certain doses. Vitamin E does not appear to reduce cancer risk in most populations. Reishi combined with chemotherapy showed more tumor shrinkage in some Asian trials but not improved survival. See the heatmap and evidence reviews below for outcomes by cancer type and supplement.
