Saffron vs Ashwagandha: Which Is Better for Mood and Stress?

Saffron and ashwagandha are both studied for a calmer, steadier day, but they lean in different directions. Saffron's trials mostly measured mood, using about 15 to 30 mg a day of a standardized extract. Ashwagandha's trials mostly measured stress and cortisol, usually with 250 to 600 mg a day of root extract. If a steadier mood is your main goal, saffron is the closer match; if everyday stress is, ashwagandha is, and many people take both.

Key Takeaways

• A 2026 systematic review of 31 randomized trials found saffron's benefits centered on mood and sleep at 15 to 30 mg a day, and ashwagandha's on stress, sleep and cortisol, with both generally well tolerated (Alyami, 2026).
• In 128 adults with everyday low mood, 28 mg a day of saffron extract for 4 weeks improved mood scores compared with placebo (Kell et al., 2017).
• In 64 adults with a history of chronic stress, 300 mg of ashwagandha root extract twice a day for 60 days lowered stress scores and serum cortisol compared with placebo (Chandrasekhar et al., 2012).
• Both have sleep research behind them, so the real difference is the main goal: mood for saffron, stress for ashwagandha.
• They work in different ways and were each tested on their own; taking both at their studied amounts is a common approach.

Saffron vs Ashwagandha at a Glance

The amounts and timings below come from the trials described further down.

	Saffron extract	Ashwagandha
What it is	An extract of saffron, the spice from the Crocus sativus flower	The root of Withania somnifera, an evergreen shrub
Main focus in trials	Mood, plus sleep	Stress and cortisol, plus sleep
Amount studied	15 to 30 mg a day of standardized extract	Mostly 250 to 600 mg a day of root extract
Trial length	4 to 6 weeks in the trials below	8 weeks or 60 days in the trials below
How it is taken	Daily, at a time you will remember	Daily, often split into two doses
Most common side effect	Mild, short-lived stomach upset	Mild stomach upset, loose stools or drowsiness

The clearest single comparison so far is a 2026 systematic review that pulled together 31 randomized trials of the two plants. Saffron showed benefits on mood and sleep measures at 15 to 30 mg a day of standardized extract. Ashwagandha showed benefits on stress and sleep measures at 30 to 600 mg a day of standardized extract, along with a pooled drop in cortisol. Both had generally favorable safety profiles (Alyami, 2026).

What Saffron Is Studied For

A steadier mood

Mood is where saffron has the most research. In a double-blind trial, 128 adults who reported low mood, but had no diagnosis, took 28 mg or 22 mg of saffron extract a day, or a placebo, for 4 weeks. The 28 mg dose lowered negative mood scores and stress-related symptom scores compared with placebo; the 22 mg dose did not (Kell et al., 2017). So when you compare labels, the amount matters.

Sleep quality

In a randomized, double-blind trial, 66 adults with mild to moderate sleep complaints took 15.5 mg of saffron extract or a placebo every day for 6 weeks. Saffron increased time in bed measured by a wrist tracker, made it easier to get to sleep, and improved questionnaire scores for sleep quality and sleep duration. The placebo group did not change (Pachikian et al., 2021).

A single stressful moment

Saffron has also been tested in a lab stress challenge. In a small crossover study, 19 healthy young men took a single 30 mg dose of saffron extract or a placebo before a standard stress test. After saffron they rated their stress lower, and the peak in their cortisol came later than on placebo (Pouchieu et al., 2023). It was an early, single-dose study, but it shows saffron touches the stress response too. Our full guide to saffron supplement benefits covers more of its research, including women in perimenopause.

What Ashwagandha Is Studied For

Everyday stress and cortisol

Ashwagandha is an evergreen shrub, and most supplements use extracts of its root, which is rich in compounds called withanolides (NIH Office of Dietary Supplements). Stress is its best-studied use. In a double-blind trial, 64 adults with a history of chronic stress took 300 mg of root extract or a placebo twice a day for 60 days. The ashwagandha group scored lower on every stress scale used, and their serum cortisol fell compared with placebo (Chandrasekhar et al., 2012).

A review of 12 randomized trials with 1,002 adults aged 25 to 48 found lower stress scores with ashwagandha than with placebo, and the dose analysis favored 300 to 600 mg a day (Akhgarjand et al., 2022). For other ingredients studied for the stress hormone, see supplements to lower cortisol.

Restful sleep

In an 8-week trial, 60 healthy adults with high stress scores took 250 mg or 600 mg a day of root extract or a placebo. Both doses lowered perceived stress and serum cortisol, and the ashwagandha groups rated their sleep better than the placebo group (Salve et al., 2019). A review of 5 trials with 400 adults found a small but significant improvement in overall sleep, larger at 600 mg a day or more and after 8 weeks or more (Cheah et al., 2021). Our guide to ashwagandha benefits goes through every one of these trials in more depth.

Who Might Choose Which

Both plants support a calmer day, so the better pick depends on what you notice most.

• Saffron may suit you if everyday low mood is your main concern and you want a steadier mood day to day. It also suits people who prefer a small daily amount: the trials used 15 to 30 mg.
• Ashwagandha may suit you if you feel stretched by everyday stress and want an ingredient whose trials measured stress scores and cortisol over 8 weeks or more.
• If you want both mood and stress support, taking the two together is a common approach, covered next.

If you are weighing other calming ingredients too, our guide to the best supplements for stress and mood puts the options side by side. If rhodiola is also on your list, our guide to rhodiola vs saffron compares it with saffron for stress, mood and fatigue.

Taking Saffron and Ashwagandha Together

Saffron and ashwagandha were each tested on their own, and many people take them side by side because they are studied for different things: saffron for mood, ashwagandha for stress and cortisol. The simple approach is to keep each at the amount its trials used and take both daily.

• Timing. The trials gave both daily. Breakfast is easy to remember; move ashwagandha to the evening if it makes you sleepy.
• With food. Mild stomach upset is the most common side effect of each, so taking them with a meal helps.
• Prescription medicine. If you take any prescription medicine, especially for mood, check with your clinician before adding either one.

Benefits build with consistent daily use: months 1 to 2 can bring early changes, and 3 months and beyond is where the full benefit builds.

Safety: Saffron vs Ashwagandha

Both are well tolerated by most people at the amounts used in studies.

Saffron. A 2026 review of 102 clinical trials found that the side effects reported with saffron were mostly minor, with stomach upset the most common (Hasheminasab et al., 2026). Sticking to the 15 to 30 mg a day used in trials is the simplest rule.

Ashwagandha. A 2026 review of 23 randomized trials with 2,317 healthy adults, using standardized root extract at 125 to 600 mg a day for up to 180 days, found liver, kidney, blood and hormone markers within normal ranges and no serious side effects linked to ashwagandha. Mild ones, such as stomach discomfort, headache and short-lived drowsiness, showed up in the comparison groups too (Coope et al., 2026). Case reports have linked ashwagandha to liver reactions, mostly with non-standardized or multi-ingredient products, and it might affect thyroid function, so people who are pregnant or breastfeeding, have liver problems or take thyroid medication should ask a clinician first (NIH Office of Dietary Supplements). Our guide to ashwagandha side effects has the details. For the saffron side, see our guide to saffron side effects.

Where Our Saffron Capsules and Forage Fit

Saffron Mood and Calm Capsules (coming soon). Our Saffron Mood and Calm Capsules pair 28 mg of saffron extract with 200 mg of L-theanine per serving in the planned formula. That saffron amount matches the 28 mg dose that improved mood scores in the 4-week trial above, and 200 mg a day is the L-theanine amount that, in a 4-week placebo-controlled trial of 30 healthy adults, lowered stress-related symptom scores and improved sleep quality scores (Hidese et al., 2019). They are coming soon: join the waitlist on the product page to hear when they launch, and no payment is taken. Our saffron extract ingredient page covers the ingredient itself.

Forage. If ashwagandha is the side you lean toward, our Forage capsules include 100 mg of ashwagandha root extract per 2-capsule serving, alongside 8:1 fruiting body extracts of lion's mane, cordyceps and reishi (200 mg each) and chaga, maitake, turkey tail and shiitake (150 mg each), plus 100 mg of Himalayan shilajit extract, with ginger extract in vegan capsules. Take 2 capsules daily in the morning, with or without food. Forage is built as a daily adaptogen blend, so ashwagandha works beside the mushrooms rather than at the single-ingredient amounts used in the trials above. It is made with third-party tested ingredients. For daily habits that support a calmer nervous system, see our stress, mood and nervous system guide.
