A new Australian trial has just added to one of the most interesting stories in mood research: saffron. Here is what the study actually found, who it was done in, and how much weight it can really carry.
Saffron has been studied for mood for close to two decades, and most of that work has used a branded extract called affron®. In 2026, a team in Perth published a trial run only in women, using the same 28mg daily dose you find in supplements on the shelf. It is encouraging. It is also easy to misquote. So let's read it the way a pharmacist would.
In short: Saffron is one of the most researched natural ingredients for mood. In a 2026 Australian trial, women taking 28mg of affron® saffron extract a day were nearly twice as likely to reach a meaningful improvement in mood after 12 weeks as women on placebo (48.8% vs 25.6%). Research also suggests saffron may support self-esteem, sleep quality and premenstrual symptoms. The research dose is 28mg of affron® a day.
What is affron®, and why is saffron studied for mood?
Saffron is the dried stigma of the Crocus sativus flower, the same spice that turns paella gold. affron® is a specific extract of it: a dry concentrate made by extracting saffron in water at a 3:1 ratio, so 28mg of extract is equivalent to 84mg of dry saffron stigma. That consistency matters, because it means trials using affron® are testing the same thing each time.
The wider saffron research has been promising for years. A 2019 meta-analysis in Nutrition Reviews pooled 23 randomised trials and found that saffron improved mood scores more than placebo, with large effects on paper. But the authors also flagged publication bias and a narrow spread of study locations, and a 2021 review mapping all of saffron's health research concluded that bigger, better and more diverse trials were still needed.
In other words, the early signal was strong, but built on a lot of small studies. That is exactly why each well-run new trial is worth paying attention to.
Research note: In a 2026 randomised, double-blind trial, 48.8% of women taking 28mg of affron® a day had a clinically meaningful improvement in mood scores after 12 weeks, compared with 25.6% on placebo (Lopresti and Smith, Frontiers in Nutrition).
The 2026 affron® study: real results for women
Researchers at Clinical Research Australia in Perth recruited 86 women who were experiencing low mood and poor sleep. Half took 28mg of affron® a day and half took an identical-looking placebo, for 12 weeks. Neither the women nor the researchers knew who was getting which.
The results showed that women taking saffron saw their mood scores improve more than those on placebo. Nearly half of them reached a clinically meaningful improvement, almost twice the rate of the placebo group.
The benefits went beyond mood. Self-esteem improved more in the saffron group, and so did sleep-related impairment, a measure of how much poor sleep gets in the way of your day: feeling foggy, flat or less able to get things done. Saffron was also well tolerated, with no serious side effects reported.
The women in this trial were aged 50 to 70, and research in younger women is still growing. But it adds to a consistent picture: there is promising evidence for affron® having a positive effect on mood.

Saffron and sleep quality
Mood and sleep are closely linked, and saffron research has started to explore both. A 2023 systematic review of five randomised trials, 379 people in total, found that saffron may improve sleep quality.
The 2026 affron® trial fits that picture too. Women taking saffron reported that they were less affected by sleep-related impairment.
What can saffron be used for?
Put together, the clinical research on saffron now spans a wide range of outcomes that matter to women. These are the areas where studies have reported encouraging results.
How much saffron is the research dose?
Most saffron mood studies have used 28 to 30mg of extract a day, taken for 4 to 12 weeks. For affron® specifically, the research dose is 28mg a day, equivalent to 84mg of dry saffron stigma.
As a pharmacist, the thing I always look at next is dose, as a supplement is only effective if the dose matches the evidence. Many products list saffron on the label at a fraction of that, or hide it inside a proprietary blend, so it is worth checking.
Saffron FAQs
What is affron®?
affron® is a branded saffron extract made from the stigma of the Crocus sativus flower. It is a 3:1 water-extracted dry concentrate, so 28mg of affron® is equivalent to 84mg of dry saffron stigma. It is the saffron extract used in many of the clinical trials on saffron and mood.
Does saffron help with mood?
Research suggests it may. A 2019 meta-analysis of 23 randomised trials found saffron improved mood scores more than placebo, and a 2026 trial found women taking 28mg of affron® a day were nearly twice as likely to reach a meaningful mood improvement as those on placebo.
How long does saffron take to work?
Saffron is not an instant fix. Clinical trials have typically run for 4 to 12 weeks, and the 2026 affron® trial measured its results after 12 weeks of daily use.
Can saffron help with PMS?
A 2026 meta-analysis of seven randomised trials, including 612 women, found saffron produced a moderate improvement in premenstrual symptoms and period pain compared with control.
Is saffron safe to take?
In the 2026 trial, saffron was well tolerated with no serious side effects reported. Saffron supplements are not recommended during pregnancy or breastfeeding, and if you take prescription medication for your mood, check with your GP or pharmacist first.
Where saffron fits in MAG+ Mood & Focus
This research is exactly why we chose affron® for MAG+ Mood & Focus. Every serve contains 28mg of affron®, the same extract at the same daily dose used in the 2026 trial.
Saffron works alongside other carefully chosen ingredients. Each 5g serve also delivers 320mg of elemental magnesium from magnesium glycinate, 200mg of AlphaWave® L-theanine, and 300mg each of tyrosine, glutamine, taurine and glycine. Together, they are designed to support a balanced mood and a clearer head: calm with focus, without feeling sedated.
Saffron has earned its place. If you have been looking for mood support that is backed by real research and transparent about what is inside, this is where I would start.
