Saffron & Wellness
What does the science say?
Saffron contains naturally occurring compounds including
crocin, crocetin, picrocrocin, and safranal. Researchers have
investigated saffron and saffron extracts in a variety of
areas of human health.
Below are selected peer-reviewed clinical studies and
systematic reviews. We encourage you to read the original
research and evaluate the evidence for yourself.
A Growing Body Of Research
From traditional spice to modern research.
Modern clinical research has investigated saffron in areas
including mood, anxiety, premenstrual symptoms, vision, and
cognitive function. The strength of evidence varies by topic,
study design, dose, preparation, and population.

RESEARCH 01
Mood & Emotional Well-Being
Effect of saffron on depression, anxiety and mood disorder:
A GRADE assessed systematic review and meta-analysis
A 2026 systematic review and meta-analysis evaluated
34 randomized controlled trials involving 1,769
participants. The authors reported improvements in
some self-reported depression and anxiety measures,
while noting that results were not consistent across
all clinician-rated outcomes.
What the evidence suggests
Saffron is being actively investigated as a possible
complementary approach for mood-related symptoms.
This research does not establish saffron as a
treatment for depression or anxiety.

RESEARCH 02
Depression & Anxiety
Effect of saffron supplementation on symptoms of
depression and anxiety: A systematic review and
meta-analysis
A 2019 systematic review and meta-analysis examined
23 randomized controlled studies. The authors found
positive effects on depressive and anxiety symptoms
compared with placebo, while also identifying
publication-bias concerns and the need for additional
research.
What the evidence suggests
Multiple clinical trials have reported promising
findings, but the evidence should be interpreted
cautiously and does not mean saffron replaces
professional medical treatment.

RESEARCH 03
Premenstrual Symptoms
Saffron and premenstrual syndrome: randomized,
double-blind, placebo-controlled clinical research
Clinical research has investigated saffron for symptoms
associated with premenstrual syndrome. A double-blind,
randomized, placebo-controlled trial reported improvements
in PMS symptom measures among the participants studied.
Additional evidence
A more recent systematic review and meta-analysis of
randomized clinical trials also reported beneficial
effects on PMS symptoms and dysmenorrhea, while
emphasizing the limitations of the available evidence.

RESEARCH 04
Vision & Retinal Function
Saffron therapy for mild/moderate age-related
macular degeneration
Randomized, double-blind, placebo-controlled research
has investigated oral saffron supplementation in people
with mild to moderate age-related macular degeneration.
Other controlled research has also examined retinal
function following saffron supplementation.
What the evidence suggests
Saffron is an area of ongoing ophthalmic research.
These studies do not establish saffron as a treatment
or cure for eye disease.

RESEARCH 05
Cognitive Function
Effects of saffron on cognitive function:
A systematic review of randomized controlled trials
Researchers have conducted randomized controlled trials
examining saffron and cognitive function in people with
mild cognitive impairment and Alzheimer's disease.
Important context
A systematic review found promising results but
specifically noted that some included studies had
potentially high risk of bias. Larger, higher-quality
trials are needed before firm conclusions can be made.
Understanding The Evidence
Research is not the same as a promise.
Many saffron studies use standardized saffron extracts,
specific doses, and controlled supplementation protocols.
Those preparations are not necessarily equivalent to culinary
saffron threads or every saffron product on the market.
For that reason, Imperial Saffron does not use these studies
to promise that consuming our saffron will prevent, treat,
or cure a disease. Instead, we believe customers should have
access to the underlying research and be able to make their
own informed decisions.
Educational Information
The information presented on this page is for educational
purposes only and is not intended to diagnose, treat, cure,
or prevent any disease. The studies linked above investigate
saffron or saffron extracts under specific research conditions
and should not be interpreted as proof that Imperial Saffron
products produce the same effects. Always consult a qualified
healthcare professional regarding medical conditions,
medications, pregnancy, or supplementation decisions.
