How to take it
- Standard dosage: 30 mg of standardised saffron extract per day (standardised to 2% safranal or 3.5% lepticrosalides)
- Clinical range: 15-30 mg twice daily was used in most clinical depression trials
- Onset: Mood benefits typically emerge within 1-2 weeks, with full effects by 4-6 weeks
- Quality matters: Saffron is heavily adulterated in the supplement market - choose products standardised to safranal or crocin content from reputable...
- Culinary saffron: Cooking-grade saffron threads can provide benefits but dosing is imprecise and expensive compared to standardised extracts
Watch out for
- Well tolerated at standard doses: Side effects are rare at 30 mg/day and typically limited to mild nausea, dizziness, or dry mouth
- High-dose toxicity: Doses above 200 mg/day may cause adverse effects. Doses above 5 g are potentially toxic - but this is over 150 times the therapeutic dose
- Pregnancy: High doses of saffron may stimulate uterine contractions. Avoid therapeutic-dose supplementation during pregnancy. Culinary amounts are safe
- Serotonergic interactions: Use caution when combining with SSRIs, SNRIs, or other serotonergic compounds due to theoretical risk of serotonin excess
- Bipolar disorder: As with any mood-elevating compound, use caution and medical supervision in bipolar disorder
The science, if you're curious.
- Crocin and safranal inhibit serotonin reuptake in synapses, increasing serotonin availability - similar to SSRI antidepressants but with a gentler mechanism
- Crocetin acts as a non-competitive NMDA receptor antagonist, potentially reducing excitotoxicity
- Crocin suppresses NF-kB activation and reduces pro-inflammatory cytokines (TNF-alpha, IL-6) in brain tissue
- Saffron extracts increase brain-derived neurotrophic factor expression, supporting neuroplasticity and neurogenesis
Where to find it
- Standardised extracts: Affron (affron 3.5% lepticrosalides) and Saffr'Activ are the most clinically studied branded extracts
- Capsules: Available from nootropic and supplement retailers, typically in 15-30 mg capsules
- Saffron threads: Whole stigmas from Iranian, Spanish, or Kashmiri sources - look for ISO 3632 grading
