Best for chronic generalized anxiety
Amazon →
Thorne Ashwagandha (Shoden®)
Shoden® extract — 120 mg, root + leaf
Shoden® extract standardized to 35% withanolide glycosides — the most concentrated ashwagandha form clinically. Best evidence for cortisol reduction and HPA-axis modulation in chronic stress patterns. Effects build over 4-8 weeks of daily use — suitable for ongoing background anxiety, not acute situations. Thorne is the most-trusted clinical brand.
Best for acute situational stress
Amazon →
Thorne L-Theanine
Pure L-theanine — 200 mg
L-Theanine takes effect within 30-40 minutes — making it ideal for situational anxiety before public speaking, important meetings, exams, or social events. Promotes alpha brain wave activity for calm focus without sedation or drowsiness. 200 mg matches the clinical trial dose. NSF Certified for Sport (tested for 200+ banned substances).
Best for 'wired but tired' / HPA exhaustion
Amazon →
Organics Ocean Magnesium Glycinate (ChelaMax)
Fully-reacted Magnesium Bisglycinate Chelate
Magnesium glycinate is foundational for the 'wired but tired' anxiety pattern — overstimulated nervous system combined with depleted energy reserves. Uses fully-reacted magnesium bisglycinate chelate (most commercial 'glycinate' is actually buffered oxide). Calming without sedation. Best taken daily over several weeks for HPA-axis recovery.
Best for sleep-disrupting anxiety
Amazon →
Sports Research Pure Saffron (affron®)
affron® saffron extract — 30 mg
affron® saffron extract has growing clinical evidence specifically for mood + sleep onset when anxiety interferes with falling asleep. Different mechanism than ashwagandha — saffron acts on serotonin and dopamine pathways. The 30 mg dose matches clinical research. Particularly useful for users whose anxiety is most disruptive at night or who experience anxiety-driven insomnia.
