5-HTP is an amino acid derivative from tryptophan acting as the direct precursor for the neurotransmitter serotonin (5-HT) and hence of melatonin in mammals.
It is found in different foods in insignificant amount but in some particular foods in a significant amount for extraction, as in Griffonia simplicifolia.
It is available as a dietary supplement.
Is there a convention about how it is best for humans to take 5-HTP?
For example, at what time of day, drug interactions to avoid, etc, to increase serotonin levels in an otherwise healthy person, in cases of indication (perhaps emotional eating or recovering from some form of depression).
