Saffron Extract (affron®)
Crocus sativus stigma
Last reviewed
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®): how the options compare
Unusually, all three products pass — each contains a named, standardized extract with genuine trial evidence behind it. Sports Research is our pick: affron® at the 30 mg studied dose, HPLC-standardized to ≥3.5% lepticrosalides, in an easily-absorbed softgel. Solaray also uses affron® (marketed under its Lepticrosalides® marker compound), standardized to the same ≥3.5% level — a close second. 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 than affron®. All three are genuinely good choices; we're highlighting a preference, not a clear winner. (We previously listed a California Gold Nutrition affron® product here; we couldn't confirm an active Amazon.com listing for it, so we replaced it with the verified Solaray option.)
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
