Does turmeric help with anxiety? What the research does and doesn't show

The evidence doesn't support turmeric or curcumin, at any dose, as a treatment for anxiety. A 2024 meta-analysis pooling 8 trials found a significant effect on anxiety scores overall, but the trials disagreed with each other so much — a heterogeneity statistic of 95.6% — that the pooled number isn't a reliable single estimate, and most of the supporting trials studied people with a diagnosed diabetes complication, not everyday anxiety in a general population.

What the evidence doesn't support

It doesn't support curcumin as a treatment for anxiety, panic disorder or generalized anxiety disorder. It doesn't support turmeric powder at a culinary or typical capsule amount, since none of the trials below used it — they used a concentrated curcumin extract, sometimes engineered for better absorption (nano-curcumin, or curcumin combined with piperine). And it doesn't support extending results from people with a diagnosed diabetes complication to someone without one; that's a different, narrower population than a general anxious adult.

What the trials found

The largest body of evidence is a 2024 systematic review and meta-analysis that pooled 8 randomized controlled trials, 567 people total, searching four databases through August 2023. The pooled result found a statistically significant reduction in anxiety symptoms with curcumin versus placebo. But the heterogeneity between trials was extremely high (I2=95.6%), which means the individual trials disagreed with each other substantially rather than converging on a consistent effect size. The abstract doesn't report one dose across the 8 trials, and the authors themselves called for more high-quality studies given the limited number and inconsistency of the trials included.

Two of the more detailed trials illustrate why that inconsistency matters. An 8-week trial of 80 people with diabetes and diagnosed peripheral nerve damage gave 80 mg/day of nano-curcumin and found a significantly greater reduction in anxiety and depression scores than placebo, though stress scores didn't differ significantly between groups. A separate 12-week trial of 60 people with diabetic retinopathy gave 1,010 mg/day of curcumin combined with piperine and found significant improvements in sleep quality, depression, anxiety and stress scores versus placebo. Both are real, positive results — and both were run in small samples of people with a specific diagnosed diabetes complication, using different curcumin formulations and doses from each other, which is part of why a meta-analysis combining trials like these produces such an inconsistent pooled result.

No trial in this literature tested a general population without a diagnosed condition, and none tested turmeric powder as opposed to a concentrated, often specially formulated curcumin extract.

Trial	Population	Dose	Result
2024 meta-analysis, 8 RCTs	567 people, mixed populations	Varied; not given as one figure	Significant pooled effect, but 95.6% heterogeneity
Nano-curcumin RCT	80 adults, diabetic peripheral neuropathy	80 mg/day, 8 weeks	Significant reduction in anxiety and depression scores; no effect on stress
Curcumin + piperine RCT	60 adults, diabetic retinopathy	1,010 mg/day, 12 weeks	Significant improvement in sleep, depression, anxiety and stress scores

Questions people ask

Is turmeric good for anxiety?

The research doesn't answer that for a general population. The two most detailed supporting trials recruited people already diagnosed with a diabetes complication, and the overall pooled evidence is inconsistent enough that a systematic review's own authors called for more high-quality studies before drawing a firm conclusion.

How much turmeric should I take for anxiety?

There isn't an established dose. The trials above used different curcumin formulations (nano-curcumin, curcumin plus piperine) at different amounts, in different diagnosed populations, so no single number transfers to turmeric powder or a general anxious adult.

Can turmeric make anxiety worse?

None of the trials reviewed here reported anxiety or a related psychological symptom as a side effect of curcumin. The documented side effects of turmeric and curcumin supplements are gastrointestinal and, less commonly, liver-related.

Is curcumin better than turmeric for anxiety?

The trials above used concentrated curcumin extracts, not turmeric root powder, so there's no comparable research on turmeric powder for anxiety to set against it. That's a difference in what's been studied, not a statement that one works and the other doesn't.

When to talk to a doctor

Anxiety that interferes with daily life, work or sleep is worth raising with a doctor. Turmeric and curcumin are not a treatment for anxiety, panic disorder or generalized anxiety disorder, and nothing in the evidence above supports using either as a substitute for an evaluation, therapy or medication a doctor might recommend. If you take medication for anxiety or any other condition, or are pregnant or nursing, talk to a doctor before adding any supplement.
