Comparison
Ashwagandha vs Honokiol (Magnolia Bark)
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.
Honokiol (Magnolia Bark)
Bioactive lignan from Magnolia bark. Anxiolytic via GABA-A modulation; also studied for sleep, mood, and neuroprotection.

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 Honokiol (Magnolia Bark) if
Honokiol (Magnolia Bark) is the better fit when your goal aligns with its mechanism (Honokiol and magnolol are positive allosteric modulators of GABA-A receptors at sites distinct from benzodiazepines) and the dose range (250–1000mg) suits your protocol. Half-life is —h.
