Ame, found this product on the net...called Serotain, it contains 5htp...note what it says re: 5htp VS. tryptophan (and also SJW)....I don't know if those claims are true or not....:
How Does Serotain™ Compare to Tryptophan?
The natural 5-HTP in Serotain™ is readily absorbed from an oral dose with approximately 70% bioavailability and easily crosses the blood brain barrier(2). The absorption of tryptophan from the intestine is significantly less than 5-HTP from the intestine and much of the absorbed portion is metabolized by enzymes found in the liver(3).In a double-blind comparative study, tryptophan was not as effective as an antidepressant as was 5-HTP(4).
Why Use Serotain™ Instead of St. John's Wort?
Because there are many potentially active compounds in St. John's wort it is very difficult to determine its precise mechanism of action(1).Independent bioassay results indicate that Serotain™ appears to be safer and significantly more effective than St. John's wort 0.3% extract in increasing serotonin levels.
