Personally I would go with valerian root. Just make sure it is standardized to 0,8% of valerenic acid... For me 900 mg do wonders for anxiety and muscle spasm, I would compare it to 0,5 mg of klonopin (for me). Your mileage may vary.
Other anxiolytic supplements include hops, passiflora (make sure it is standardised fot vitexin), relora (make sure it is standardized for magnolol and honokiol) and kava kava (make sure it is standardized for at least 30% of kavalactones). That's what comes to mind right now... take care!
Bipolar II, social anxiety, assorted brain cooties.
What keeps me at bay:
Quetiapine 200 mg
Lamotrigine 200 mg
Venlafaxine 150 mg
Propranolol 80 mg
Non-mental issues: Hypertension, inoperable pilonidal cyst, IBS, seasonal allergy.
PRN: Pregabalin 300 mg, clonazepam 0.5 mg, tramadol 50 mg, dextropropoxyphene/ibuprofen 100/400 mg, antihistamines in spring and autumn (diphenhydramine, cyproheptadine, clopheniramine).
