When to take Saffron
Also known as Crocus sativus, saffron extract
Saffron can be taken at any time of day, because no study has compared morning and evening use. What matters more is taking it every day, since studies ran for about 2 to 8 weeks.

Timing
| Best time | Any time of day |
|---|---|
| Food | With or without food |
| Fat-soluble | No |
- Any time; consistency matters more than timing.
- In one 8-week trial, people took one capsule in the morning and one in the evening, at least 30 minutes after a meal.
- Sleep studies lasted 2 to 8 weeks and did not report a best time of day to take it.
Check with your doctor first if…
- Pregnancy or breastfeeding: there is little safety data, so reviewers list pregnant and breastfeeding women as a high-risk group. Ask your doctor first.
- Blood thinners: saffron may affect how platelets work, and one case of bleeding was reported in a person taking a blood thinner with saffron. Ask your doctor first.
- Mood or mental health medicine: reviewers advise extra care for people with mental health conditions. Talk to your doctor before adding saffron.
- Side effects: the most common are stomach upset (nausea, appetite changes, constipation), headache, dry mouth and dizziness. They are usually mild and go away.
- Large amounts: a safe upper limit for high doses has not been set. Stay within the amounts used in studies.
Amounts studied
Trials commonly studied 15–100 mg/day of saffron or saffron extract; one 8-week mood trial used 30 mg/day. Sleep studies mostly used 7.5–100 mg/day for 2–8 weeks.
Follow the serving size on your product’s label.
What the research says
| Area | Evidence | Summary |
|---|---|---|
| Mood | Moderate | A review of 23 trials found saffron improved mood scores more than placebo. The authors warn that some results may be overstated and most trials came from one region.[1] |
| Sleep quality | Limited | A review of 8 small trials found better sleep quality and longer sleep with saffron. The certainty of the evidence was very low to moderate.[2] |
| Stress | Limited | In an 8-week trial of adults with everyday low mood or stress, 30 mg/day of saffron extract did not change anxiety scores. Heart rate patterns during a stress test held steadier than with placebo.[3] |
Questions
Should I take saffron at night?
You can, but no study has shown night is better than morning. One trial split the dose between morning and evening after meals. Taking it daily matters more than the hour.
How long does saffron take to work?
Studies lasted about 2 to 8 weeks. There is no proven day when effects start, so give it several weeks of daily use.
Can I take saffron every day?
Yes, studies gave it daily for up to about 8 weeks and side effects were usually mild. Less is known about use for many months, so check in with your doctor if you plan long-term use.
Can I take saffron with antidepressants?
Some trials gave saffron together with antidepressant medicine, but under a doctor's care. Talk to your doctor before combining them.
Is saffron safe during pregnancy?
There is not enough safety data for pregnant or breastfeeding women. Reviewers list them as a high-risk group, so ask your doctor first.
