Saffron Extract and medications.
Saffron Extract is in the Distil supplement database, evidence Grade B. The page below lists every medication we have explicitly assessed it against.
Saffron extract is a concentrated preparation from the Crocus sativus flower, most often standardised as Affron or Satiereal. The active compounds appear to influence serotonin signalling, which is the likely mechanism behind its effect on mood. The Grade B evidence supports a mild antidepressant action, with some trials placing it close to low-dose antidepressant medication, plus modest appetite reduction and anxiety relief. The honest limit is that only the standardised extracts have been trialled. Generic saffron powder does not carry the same evidence, and the studies are relatively small. The interaction that matters most is with SSRIs: saffron adds to serotonergic activity, so combining the two needs GP review rather than a casual pairing. It is also best avoided in bipolar disorder unless a psychiatrist is guiding it, because saffron acts like a mild antidepressant, and antidepressant-acting treatments can occasionally tip mood toward mania or hypomania in bipolar disorder. It also has mild blood-thinning activity, so caution applies with anticoagulants. Typical doses run from 28 to 88mg. If you are on a serotonergic medication, treat saffron as a clinical decision, not a self-managed add-on.
Below are the 33 documented pairs we have explicitly assessed for Saffron Extract: 7 red and 26 amber. The pairs cluster around 2 mechanisms: Additive serotonergic activity and Additive glucose lowering. Every call is cited to either a clinical reference (PMID) or the British National Formulary. Anything not listed here is either still to be assessed or beyond our database scope. The checker beneath surfaces assessments by medication, and the missing-item form at the bottom of the page routes any uncatalogued medication into our next curation pass.
Documented interactions
Last reviewed 30 June 2026. Each interaction below lists the evidence its assessment drew on: some rest on studies of the exact pair, others on mechanism evidence, where a citation may support one part of the reasoning rather than the exact combination. The evidence line on each entry says which.
Additive serotonergic activity
Red Does interact with Isocarboxazid?
Saffron has its own antidepressant effect that appears to act on serotonin, and isocarboxazid is an MAOI that blocks serotonin breakdown. Stacking the two could push serotonin too high, risking serotonin syndrome. We treat this as a do-not-combine pair without specialist sign-off.
Evidence: Based on an established mechanism, with no direct study of this exact combination yet.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Red Does interact with Linezolid?
Saffron has its own antidepressant effect that appears to act on serotonin, and linezolid is an antibiotic that also acts as an MAOI, blocking serotonin breakdown. Stacking the two could push serotonin too high, risking serotonin syndrome. We treat this as a do-not-combine pair without specialist sign-off.
Evidence: Based on an established mechanism, with no direct study of this exact combination yet.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Red Does interact with Moclobemide?
Saffron has its own antidepressant effect that appears to act on serotonin, and moclobemide is an MAOI (the reversible kind) that blocks serotonin breakdown. Stacking the two could push serotonin too high, risking serotonin syndrome. We treat this as a do-not-combine pair without specialist sign-off.
Evidence: Based on an established mechanism, with no direct study of this exact combination yet.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Red Does interact with Phenelzine?
Saffron has its own antidepressant effect that appears to act on serotonin, and phenelzine is an MAOI that blocks serotonin breakdown. Stacking the two could push serotonin too high, risking serotonin syndrome. We treat this as a do-not-combine pair without specialist sign-off.
Evidence: Based on an established mechanism, with no direct study of this exact combination yet.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Red Does interact with Rasagiline?
Rasagiline is an MAO-B inhibitor used for Parkinson's, and saffron has its own antidepressant effect that appears to act on serotonin. Combined, serotonin can rise too high because there is less of the enzyme available to break it down, risking serotonin syndrome. We treat this as a do-not-combine pair without specialist sign-off.
Evidence: Based on an established mechanism, with no direct study of this exact combination yet.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Red Does interact with Selegiline?
Selegiline is an MAO-B inhibitor used for Parkinson's, and saffron has its own antidepressant effect that appears to act on serotonin. Combined, serotonin can rise too high because there is less of the enzyme available to break it down, risking serotonin syndrome. We treat this as a do-not-combine pair without specialist sign-off.
Evidence: Based on an established mechanism, with no direct study of this exact combination yet.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Red Does interact with Tranylcypromine?
Saffron has its own antidepressant effect that appears to act on serotonin, and tranylcypromine is an MAOI that blocks serotonin breakdown. Stacking the two could push serotonin too high, risking serotonin syndrome. We treat this as a do-not-combine pair without specialist sign-off.

Reviewer-flagged: awaiting clinical-reviewer sign-off.
Amber Does interact with Amitriptyline?
Saffron has its own mild antidepressant effect that appears to act on serotonin, and amitriptyline raises serotonin too. Taking them together may add up. Most people tolerate it, but discuss it with your GP before stacking, especially if your dose has recently changed.
Evidence: Limited human data, based on case reports and a known mechanism.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Amber Does interact with Buspirone?
Saffron has its own antidepressant effect, possibly through serotonin-related pathways, and buspirone acts on serotonin receptors. Combining them may add to the serotonergic effect.

Additive glucose lowering
Amber Does interact with Gliclazide?
Saffron can modestly lower blood sugar. Gliclazide already lowers blood sugar, so taking them together may add up and could push your glucose too low. If you take both, monitor your blood glucose, especially in the first few weeks, and your doctor may need to adjust the gliclazide.
Evidence: Limited human data, based on case reports and a known mechanism.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Amber Does interact with Insulin glargine?
Saffron can modestly lower blood sugar on top of the insulin you inject, which may increase the chance of glucose going too low. If you take saffron with insulin, monitor your blood glucose closely, especially early on, and your doctor may need to adjust your insulin dose.
Evidence: Limited human data, based on case reports and a known mechanism.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Amber Does interact with Metformin?
Saffron can modestly lower blood sugar, and metformin lowers blood sugar too, so the two may add up. The combination is generally manageable, but monitor your blood glucose when you start saffron or change the dose, and your doctor may adjust the metformin if needed.
Evidence: Limited human data, based on case reports and a known mechanism.

Read the full methodologyA full supplement review, built around you, not a generic stack.
The free checker answers one interaction question at a time. A Distil report reviews the bigger picture: your goals, diet, medications, current supplements and any blood results you provide, then shows what appears worth keeping, changing, adding or leaving out.
- what your diet already covers, so you are not adding a capsule for something food is already handling
- which evidence-graded compounds are worth considering for your goals, and which were considered but left out
- what to keep, change or stop from what you already take, plus the order to introduce anything new
- how your medications and complete supplement stack fit together, with daily timing and a clear point for reassessment
The interaction check is one section of the full report. You also get the reasoning behind each recommendation and the evidence references used.
