The evidence in words

What it is

Saffron is the spice from Crocus sativus stigmas, standardized to crocin and safranal for supplements. Its mood evidence outstrips most botanicals.

How it works

Its carotenoids appear to have serotonergic and antioxidant/anti-inflammatory actions relevant to depression.

What the evidence shows

Multiple small-to-moderate RCTs and meta-analyses find ~30 mg/day standardized saffron reduces mild-to-moderate depressive symptoms, sometimes comparably to low-dose antidepressants, with signals for anxiety and PMS. Trials are small and often from a few groups, so confidence is moderate, but it is one of the better-supported mood botanicals.

How to use it

30 mg/day of a standardized extract (e.g., 15 mg twice daily).

Safety & interactions

Well tolerated at supplemental doses; culinary-scale amounts are safe, but very high doses are toxic. As a serotonergic agent, combining with antidepressants warrants caution. ssri — Serotonergic — additive load; clear with prescriber.

Bottom line

The mood botanical with the most convincing small-trial evidence: 30 mg/day standardized for mild-to-moderate low mood. Clear it with a prescriber if you're on serotonergic drugs.

How it is used

As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.

Standard
30 mg/day standardized (15 mg ×2).
