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.
Choose Astragalus if
Astragalus is the better fit when your goal aligns with its mechanism (Polysaccharides activate innate immunity through TLR-4 and other receptors) and the dose range (500–3000mg) suits your protocol. Half-life is —h.
