Tryptophan
Amino AcidsKey Benefits
How It Works
L-Tryptophan is the precursor to serotonin (via 5-HTP) and subsequently melatonin. It competes with BCAAs for brain entry, so lower-protein meals enhance brain tryptophan levels. Also produces niacin (B3) and kynurenine (immune regulation). The rarest essential amino acid in food.

Recommended Dosage
500-2,000 mg daily
Best Time to Take
Evening on empty stomach (or away from protein) for sleep and mood
Recommended Form
L-Tryptophan (pharmaceutical grade)
Side Effects
Drowsiness, nausea, headache. Historical EMS contamination issue (1989) was manufacturing defect, resolved.
Drug Interactions
CRITICAL: Do NOT combine with SSRIs, SNRIs, MAOIs (serotonin syndrome risk). May interact with sedatives.
What Does The Research Say?
Research supports sleep onset and quality, mood enhancement, and cognitive function. Safer than 5-HTP for long-term use (slower, more regulated serotonin conversion). Must compete with BCAAs for brain entry.
