Can you take 5-HTP and Ashwagandha together?

Additive sedation — care with meds

Combining two mood-active supplements is possible but adds drowsiness, and 5-HTP is dangerous with antidepressants — check with a doctor if you take any psychiatric medication.

🕑 How to time them

Evening only, low doses, never with alcohol or sedatives. On SSRIs or similar medication, skip 5-HTP entirely.

Combining two mood-active supplements is possible but adds drowsiness, and 5-HTP is dangerous with antidepressants — check with a doctor if you take any psychiatric medication. 5-HTP is typically taken for mood and sleep (serotonin precursor), while Ashwagandha is used for stress, cortisol, perceived anxiety — different jobs, so people often end up with both in the cabinet.

For context: a typical daily amount of 5-HTP is 50–200 mg, and 5-HTP has no formal upper limit (use with care). A typical daily amount of Ashwagandha is 300–600 mg, and Ashwagandha has no formal upper limit (not established).
