the claim

Melatonin supplements lower cortisol levels.

the verdict
CONTESTED PARTIAL
Recorded sources
3 sources for · 1 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that melatonin supplements lower cortisol levels?

Partly. One small randomized trial in hemodialysis patients found salivary cortisol significantly lower with melatonin, and a supplement bundle containing melatonin lowered cortisol in female athletes, while a 1995 study found melatonin raised daytime cortisol in postmenopausal women and did not change it in young women. The evidence is mixed, narrow in population, and does not settle the general claim.
