Key takeaways
- Meta-analyses find saffron beats placebo for depressive symptoms, with effects similar to some antidepressants in mild-to-moderate cases.
- The usual dose is 30 mg a day, often taken as 15 mg twice daily, or 28 mg of affron®.
- Expect to wait 4–8 weeks for results.
- Never combine saffron with antidepressants without medical supervision.
What the Research Shows
Saffron's effect on mood has been tested in more randomized controlled trials than almost any other herb except St John's wort. Three meta-analyses stand out:
- Hausenblas et al. (2013) pooled five trials and found saffron significantly reduced depression scores compared with placebo, with effects comparable to antidepressants.
- Toth et al. (2019) reviewed trials in mild-to-moderate depression and concluded saffron improved symptoms, while noting the studies were small and mostly from one country.
- Marx et al. (2019) analysed 23 studies and found large effects on depression and anxiety versus placebo, and no significant difference from antidepressants.
Saffron has also been tested in people who don't have a depression diagnosis. In a 4-week trial of healthy adults with subclinical low mood, 28 mg/day of affron® improved mood and reduced tension and anxiety (Kell 2017).
Saffron vs Antidepressants
Several small head-to-head trials compared 30 mg/day of saffron with standard medication:
| Comparison | Length | Result |
|---|---|---|
| Saffron 30 mg vs fluoxetine 20 mg | 6 weeks | Similar improvement (Noorbala 2005) |
| Saffron 30 mg vs imipramine 100 mg | 6 weeks | Similar improvement, fewer side effects with saffron (Akhondzadeh 2004) |
| Saffron + curcumin vs placebo | 12 weeks | Improved depression scores (Lopresti 2017) |
These results are encouraging, but the trials were small (often 30–40 people). Don't stop or switch any medication based on them. Talk to your prescriber about whether saffron fits your plan.
Saffron for Anxiety
The same Marx meta-analysis found saffron reduced anxiety symptoms, and an adolescent trial of affron® found improvements in self-reported anxiety (Lopresti 2018). If stress and worry are your main concern, a 28 mg affron® product is a reasonable choice. Pairing it with magnesium glycinate is a common evening stack.

How to Take Saffron for Mood
- Dose: 30 mg of standardized extract a day, as 15 mg morning and evening or 28–30 mg once.
- With food: taking it with a meal reduces the chance of mild nausea.
- Consistency: take it daily. Saffron builds up over weeks rather than working within hours.
- Track it: use our free mood tracker so you can see real trends.

What to Expect, Week by Week
- Week 1–2: Most people notice little. A few report feeling slightly calmer or sleeping better.
- Week 3–4: In the affron® trial, mood improvements were measurable by week 4.
- Week 6–8: Most depression trials measured their main result here. This is the fair point to judge it.
- Week 8+: If you've noticed no benefit, saffron may not be for you. Talk to your doctor about other options.
Who Should Not Take Saffron for Mood
- People with bipolar disorder: anything with antidepressant-like activity could trigger mania.
- Anyone on SSRIs, SNRIs, MAOIs, tricyclics or triptans, unless a doctor supervises, because of the theoretical risk of serotonin excess.
- Pregnant women: high doses of saffron may stimulate the uterus.
- Anyone with severe depression or suicidal thoughts, who needs professional care first.

Frequently Asked Questions
How much saffron should I take for depression?
Most trials used 30 mg of saffron extract a day, usually 15 mg twice daily. affron® trials used 28 mg. Higher doses have not been shown to work better.
How quickly does saffron work for mood?
Some people notice changes within 2–4 weeks, but most clinical trials measured results at 6–8 weeks.
Can saffron replace my antidepressant?
No. Never stop or reduce prescribed medication without your doctor. Saffron has been studied mainly in mild-to-moderate depression, and stopping antidepressants suddenly can cause withdrawal and relapse.
Is saffron or St John's wort better for mood?
Both have evidence. St John's wort has more drug interactions, including with birth control, blood thinners and many other medications. Saffron appears to interact less but still needs care with serotonergic drugs.
Does saffron make you happy right away?
No. Saffron is not a stimulant or euphoric. Benefits build gradually over weeks.
