"Personally I take both 5-HTP and L-tryptophan because every amino acid profile I have done has shown that I was deficient in tryptophan. The body converts tryptophan to numerous substances including serotonin. 5-HTP is the most efficient means of doing this but will not substitute for tryptophan in all of the body's metabolic pathways."
