5-HTP vs L-Tryptophan
Both are commonly considered for mood, sleep, and stress. Here is how they compare and how to choose.
How to choose
Choose 5-HTP if your focus is mood, sleep, and stress. Choose L-Tryptophan if you care more about mood, sleep, and stress. Both are reasonable options for mood, sleep, and stress.
Can you take them together?
Synergy: 5-HTP is the metabolite tryptophan is converted into. It skips the rate-limiting step for a more direct serotonin boost, but stacking the two (or either with SSRIs) raises serotonin-excess risk.
