Yes — no known interaction; L-theanine promotes relaxation while melatonin times your sleep, and they're often combined.
🕑 How to time them

Yes — no known interaction; L-theanine promotes relaxation while melatonin times your sleep, and they're often combined. L-Theanine is typically taken for calm focus, takes the edge off caffeine, while Melatonin is used for sleep onset, jet lag, shift-work schedules — different jobs, so people often end up with both in the cabinet.
For context: a typical daily amount of L-Theanine is 100–200 mg, and L-Theanine has no formal upper limit (well tolerated). A typical daily amount of Melatonin is 0.5–5 mg, and Melatonin has no formal upper limit (no formal ul).
