Saffron Extract (affron®)
Crocus sativus stigma
The world's most expensive spice is also a surprisingly well-studied mood-support botanical, with several trials using standardized extracts showing meaningful effects.
Our pick, and why
Choosing a saffron extract (affron®) on iHerb
Unusually, all three products pass — each contains a named standardized extract with genuine trial evidence. Sports Research and California Gold Nutrition both use affron® at the 28–30 mg studied dose; they're effectively interchangeable on the criterion. Sports Research is our pick by a slim margin: the softgel format offers slightly better bioavailability than a dry capsule for botanical extracts. Life Extension's Satiereal® at 78 mg is a different branded extract with its own valid trial record — it's dosed higher because Satiereal is less concentrated per mg. This is the rare table where any of the three is a genuinely good choice; we're highlighting a preference, not a clear winner.
How we judge these
Named branded extract (affron® or Satiereal®), HPLC-standardized, dosed at trial-matched level.

Saffron is an unlikely entry on a supplement shelf, but standardized extracts have accumulated a genuinely interesting body of randomized trials for mood support — some comparing favorably to reference treatments in mild cases. The active compounds, crocin and safranal, are thought to influence serotonin handling.
As always, the studied population matters: most trials look at mild-to-moderate low mood, and saffron is best understood as a gentle, evidence-aware option to discuss with a professional — not a standalone fix.
What to look for
- A standardized extract (affron® is the most-studied) with stated crocin/safranal content
- Doses around 28–30 mg/day matching the trial protocols
- Reputable brands — real saffron is costly, so suspiciously cheap products are a red flag
