Melatonin vs Turmeric for inflammation: which has better evidence?
Melatonin has the stronger evidence for inflammation (Melatonin Grade B vs Turmeric Grade C). For inflammation, Melatonin has the stronger evidence grade.
Platform evidence comparison
These existing platform assessments are separate from the source-reported findings below. They do not represent a direct trial comparing these treatments.
| Melatonin | Turmeric | |
|---|---|---|
| Grade | grade B | grade C |
| Certainty | moderate | low |
| Effect | Meta-analysis of 31 clinical trials (1517 participants): melatonin significantly reduced inflammatory markers IL-1, IL-6, IL-8, and TNF versus placebo, but had no significant effect on C-reactive protein (CRP). After correcting for publication bias, effects on IL-1, IL-6, and IL-8 remained significant — a real anti-inflammatory signal on cytokines specifically, not on CRP. | small anti-inflammatory signal; bioavailability is a major limitation |
| Studied dose | varies across trials | 500–1000 mg curcumin |
| Population | adults | — |
| Safety | 1 modeled interaction(s) | 1 modeled interaction(s) |
Grade B / moderate: probably helps, and new studies are unlikely to reverse this — but could shrink the effect size.
Direct comparison evidence
There are no direct RCTs in our corpus comparing Melatonin and Turmeric head-to-head for inflammation. What we present above is an indirect comparison: each side's own trials, contrasted. This is standard practice for supplement comparisons — dose, population, and outcome-instrument differences between the two evidence bases add uncertainty on top of each side's own grade.
Can you take both?
No modeled interaction between Melatonin and Turmeric in our corpus. Absence of a recorded interaction is not proof of additive benefit — combined-effect trials are usually absent for supplement pairs, so treat "stack" claims skeptically.
Decision guidance
- If certainty matters most — choose whichever side carries the higher certainty rating at a similar grade.
- If you're on medications — check each side's interaction pages before deciding; safety differences dominate small evidence-grade gaps.
- If your population is under-studied — the smaller-effect side with better population evidence often wins over the higher-grade side studied in a different demographic.
- If cost matters — form and dose page differences (Melatonin vs Turmeric) can invert the practical winner.

Frequently asked
Which has stronger evidence: Melatonin or Turmeric for inflammation?
Melatonin carries Grade B at moderate certainty; Turmeric carries Grade C at low. The stronger evidence points to Melatonin, subject to the caveat that direct head-to-head trials are usually absent for supplement pairings.
Can I take Melatonin and Turmeric together?
No modeled interaction between Melatonin and Turmeric; combining is not documented to be problematic, but combined-effect trials are also absent, so treat additive benefit claims skeptically.
Have Melatonin and Turmeric been compared head-to-head?
Direct RCTs comparing the two for inflammation are uncommon. This page contrasts each side's own trial evidence — that is an indirect comparison, which introduces confounds from population and dose differences. See the direct-comparison block above.
