5-HTP

5-HTP from Griffonia seed. The direct serotonin precursor for mood + sleep onset.

Clinical-dose precision. No taste, no mixing, no fuss.

Dialed-inOur verdict · for short-term mood + sleep-onset protocols

5-HTP is the direct precursor to serotonin; 200mg lands in the effective trial range for mild mood and sleep-onset support. Do not stack with SSRIs or MAOIs (serotonin syndrome risk). Short-term use only. Long-term 5-HTP can deplete other neurotransmitters.
