Yes — both are calming and there's no known interaction; L-theanine works within the hour, ashwagandha builds over weeks. Ashwagandha is typically taken for stress, cortisol, perceived anxiety, while L-Theanine is used for calm focus, takes the edge off caffeine — different jobs, so people often end up with both in the cabinet.
For context: a typical daily amount of Ashwagandha is 300–600 mg, and Ashwagandha has no formal upper limit (not established). A typical daily amount of L-Theanine is 100–200 mg, and L-Theanine has no formal upper limit (well tolerated).
