Ashwagandha
Withania somnifera, the most clinically validated herbal adaptogen for stress and anxiety. Reduces serum cortisol by roughly 28% at 600 mg/day over 8 weeks. Modest evidence for sleep quality and testosterone in men. Choose the KSM-66 extract for the best-studied form.
Saffron
Crocus stigma — most expensive spice. Increasingly evidence-based antidepressant comparable to SSRIs at low doses.

Choose Ashwagandha if
Ashwagandha is the better fit when your goal aligns with its mechanism (Withanolides modulate GABA-A receptors and blunt the HPA-axis cortisol response) and the dose range (300–600mg) suits your protocol. Half-life is 6h.
Choose Saffron if
Saffron is the better fit when your goal aligns with its mechanism (Crocin (carotenoid responsible for the red colour) and safranal (volatile compound responsible for the aroma) both inhibit serotonin and dopamine reuptake at neurochemically meaningful concentrations) and the dose range (28–30mg) suits your protocol. Half-life is —h.
