What is L-Tryptophan?
L-Tryptophan is an essential amino acid--your body cannot make it, so it must come from food or supplements. It is the starting material for producing serotonin (the "feel-good" neurotransmitter) and melatonin (the sleep hormone).
The Serotonin Pathway
Tryptophan converts to 5-HTP, which then becomes serotonin, which finally converts to melatonin. By providing the initial building block, tryptophan supports this entire cascade naturally.
Why Choose Tryptophan Over 5-HTP?
Tryptophan is gentler and more physiological than 5-HTP. It allows your body to regulate conversion rates naturally. Some practitioners prefer it for long-term mood support, reserving 5-HTP for acute situations.
Sleep Support
Through its conversion to serotonin and then melatonin, tryptophan promotes healthy sleep onset and quality. Taking it in the evening can support natural sleep-wake cycles.
Competition for Absorption
Tryptophan competes with other amino acids to cross the blood-brain barrier. Taking it away from protein-rich meals, or with a small amount of carbohydrate, improves brain uptake.
