Key takeaways
- affron® at 14 mg twice daily (28 mg/day) improved sleep quality in a 28-day trial.
- Saffron is not a sedative. It seems to make sleep more restorative rather than making you drowsy.
- It may suit people whose sleep problems come with stress or low mood.
- Give it 2–4 weeks of nightly use before judging it.
What the Sleep Research Shows
The best-known study gave 63 adults with self-reported poor sleep either 14 mg of affron® twice daily or a placebo for 28 days (Lopresti 2020). The saffron group saw greater improvements in:
- Insomnia severity and overall sleep quality scores
- Restorative sleep, meaning they felt more refreshed on waking
- Mood on waking
A follow-up trial by the same group tested a single evening dose and also found improved sleep quality. Several depression trials noted better sleep as a secondary benefit. These are still small studies from a handful of research teams, so treat the results as promising rather than settled.
How Might Saffron Improve Sleep?
Researchers think it works through several pathways:
- Mood and stress: worry and low mood are among the biggest causes of poor sleep, and saffron's best-documented effect is on mood.
- Melatonin: some data suggest saffron may raise evening melatonin levels.
- Crocin: animal studies show crocin increases non-REM sleep.

Saffron vs Melatonin
| Saffron | Melatonin | |
|---|---|---|
| How it works | Supports mood, stress and sleep depth over weeks | Signals "night" to the body clock within hours |
| Best for | Stress-related, unrefreshing sleep | Jet lag, shift work, delayed sleep timing |
| Time to effect | 2–4 weeks | Same night |
| Morning grogginess | Not reported in trials | Possible at higher doses |
They work differently, so some people use both. Check with a pharmacist first if you take any other medicines.

Frequently Asked Questions
Does saffron make you sleepy?
Not in the way a sleeping pill does. Trials found better sleep quality and feeling more refreshed, without daytime drowsiness.
When should I take saffron for sleep?
Either split the dose (morning and about an hour before bed) as in the main trial, or take the full 28 mg about an hour before bed.
Can I take saffron and melatonin together?
There are no known interactions between them, but they haven't been studied together. Ask your pharmacist, especially if you take other medicines.
How long does saffron take to improve sleep?
The main trial ran for 28 days, with improvements by the end of that period. Give it at least 2–4 weeks.
